Antenna International shaped museum audio guides. For three decades, their hardware devices and scripted content model defined how institutions thought about visitor experiences. If you're on Antenna, you've lived with that model: annual contracts, proprietary devices, long production timelines, and high per-unit costs.
You're probably not here because you love it.
This article is for museums ready to migrate. Whether you're finishing a contract cycle, frustrated with costs, or simply tired of managing hardware—switching from Antenna to a modern platform is possible, but it requires understanding what you're actually moving away from.
Understanding Antenna's Contract Model
Antenna International's business is built around three interlocking commitments: hardware devices, long-term contracts, and scripted content production.
Most museums sign multi-year agreements—typically 3 to 5 years—with the device costs front-loaded and annual software/support fees for the remainder. The contract specifies the number of devices, upgrade schedules, and support terms. You're not just buying technology; you're locking into a partnership with specific people, timelines, and constraints.
The hardware piece is the keystone. Antenna's business model depends on museums owning the devices, which creates ongoing dependency: if you want to use Antenna's guides, you need Antenna's hardware. If you want to switch away, you need to figure out what to do with devices you've owned and invested in for five years.
The scripting process is equally locked-in. Antenna has a specific workflow: museum teams (or Antenna staff) write scripts, Antenna reviews and edits, professional voice actors record, and you get final audio files and metadata. This process is thorough but slow. A typical guide takes 4–8 weeks from script approval to delivery. Changes during production are possible but costly. The scripts are yours, but they're optimized for Antenna's system and playback model.
The real cost of Antenna isn't just the annual fee. It's the staff time locked into their process, the equipment and infrastructure you've built around their devices, and the expectation that managing hardware is simply part of running an audio guide program.
Switching requires breaking all three of these interlocks at the same time.
Contract Obligations and Exit Strategy
Before you can move, you need to understand what your contract actually says.
Antenna agreements typically include:
- Term lock: A fixed contract period (usually 3-5 years) with penalties for early termination or reduced scope. Some contracts allow mid-term exit if you accept a penalty. Others don't.
- Device ownership: Usually the museum owns the hardware once purchased, but there's often a restocking clause if you want to return them.
- Content ownership: Your scripts are yours; the recordings and metadata in their system are licensed, not owned.
- Support terms: Typically include hardware replacement (damaged devices), software updates, and technical support. This ends when your contract ends.
- Data and analytics: Limited or nonexistent in older Antenna contracts. Newer agreements may include basic visitor counts, but detailed behavioral data isn't a strong point.
The exit decision usually comes at renewal time. If your contract is up or coming up, the path is simple: don't renew. If you're mid-contract, you need to check whether early termination is allowed and what the penalty is. Some museums find that the early exit fee is cheaper than another year of fees and hardware management—do the math.
Document everything in writing. Send a formal notice of non-renewal 90–180 days before the contract ends. Clarify in writing what happens to hardware, whether data export is possible, and what support continues after the contract ends. Antenna will likely push back on generous exit terms (this is standard vendor behavior), so be explicit about what you need.
Content and IP During Transition
The content question is the sticky one. Your Antenna system probably contains hundreds of scripts, recordings, and metadata about thousands of museum objects.
Here's what you own and what you don't:
Scripts: You own them. They're your intellectual property. You wrote them (or paid Antenna to write them, in which case they transferred ownership to you). You can reuse them on any other platform.
Audio recordings: You probably don't own them. Antenna's standard agreement licenses you to use their recordings within their system. If you want to use them elsewhere—another platform, a podcast, printed materials—you need explicit permission or a new licensing agreement. This is the hardest piece to renegotiate because Antenna treats audio masters as a revenue stream.
Metadata and structure: The way content is organized in Antenna's system—stops, groupings, interactivity markers—is likely yours to use, though the specific formatting might be proprietary. You can export the structure, but you might need to reformat it for a new platform.
Brand assets: Any museum-specific branding, logos, or marketing materials created for your Antenna system are yours.
In practice, most museums don't try to transfer the audio. Instead, they:
-
Re-record with your new vendor. If the new platform is an AI audio guide with voice synthesis (like Musa), you only need the scripts. Re-recording takes weeks instead of months. New languages become possible at fraction of the traditional cost.
-
Refresh content alongside the platform change. Use the migration as an excuse to update outdated information, reorganize stops logically, and remove content that doesn't serve visitors anymore. Museum collections evolve; so should guides.
-
Negotiate a limited license. Some museums successfully negotiate with Antenna to maintain a read-only license to their recordings for a defined period—say, 12 months—while they transition content. This gives visitors continuity while you build new content.
-
Hybrid approach. Use existing scripts but regenerate audio through a new system. This gives you new production speed and language support without starting from scratch.
The migration isn't really a content problem; it's a production problem. Your knowledge is in the scripts and the museum expertise behind them. The recordings are just the delivery mechanism.
Hardware Return and Repurposing
Antenna devices are specialized equipment. They're not universal tablets; they're designed to run Antenna's proprietary software.
When your contract ends, here's what usually happens:
Return logistics: Antenna typically expects hardware returns within 30–60 days of contract expiration. They provide return labels or arrange pickup. You're responsible for data wipe and factory reset (Antenna's security requirement). Some contracts waive return shipping; others charge a fee.
Restocking fees: Expect to pay 15–30% of the original device cost to return used hardware. If you bought 300 devices at €400 each five years ago, returning them costs €18,000–36,000. This is painful but worth budgeting for.
Repurposing the hardware: Some museums try to keep devices and repurpose them. A tablet is a tablet—you can load Android or iOS apps onto Antenna hardware and use them for other purposes (wayfinding, gift shop checkout, educational content outside the core guide). This requires IT effort to remove Antenna's software and reconfigure the devices, but it's possible. Check your contract for clauses that prohibit this.
Donation: Some museums have negotiated to donate returned devices to educational institutions or nonprofit museums. Antenna's legal teams sometimes allow this for goodwill but rarely advertise it.
Plan for hardware return as a line item in your migration budget. Don't assume you'll recover value. Do assume you'll pay to return them or invest effort to repurpose them.
If your new platform uses AI-generated audio (most do now), you'll want to optimize your scripts. AI voice systems work differently from professional actors:
Length matters. Professional voice recording can handle 500+ word scripts per stop. AI systems work better with 150–300 words. Longer scripts are possible but sound less natural. Use the migration as a reason to tighten your writing—museum visitors prefer conciseness anyway.
Metadata and structure. New platforms often want more semantic structure: object title, category, key themes, related objects. Antenna's metadata might be flat or formatted for display. You'll spend 1–2 weeks restructuring scripts into a format your new vendor can process efficiently.
Interactivity: Antenna's branching logic and interactive features might not map directly to your new platform. Some platforms excel at interactive questions and polls. Others are simpler. Plan for 1–2 weeks to redesign interactive sequences.
Multilinguality: If you used Antenna in one language, migrating to a platform with AI-generated multilingual support opens new possibilities. Translating scripts is cheap. Professional human translation plus AI generation takes 3–4 weeks for major languages.
Tone and voice: Antenna often enforced a particular narrative voice across stops. If you're moving to AI, you might shift from formal voiceover to conversational tone. This is an opportunity, not a problem—but it requires deliberate choice and rewriting about 20% of content.
Most museums use the migration window to do this work—usually weeks 4–8 of the project timeline. Don't treat it as just conversion; treat it as an opportunity to make your guides better.
Timeline and Parallel Operation
A typical migration looks like this:
Weeks 1–2: Setup and assessment. You sign the contract with your new vendor. You conduct an audit of existing content, devices, and staff workflows. You document everything in Antenna's system that you'll need to migrate. You plan infrastructure changes (QR codes, printing, staff training).
Weeks 3–4: Content extraction and planning. You export scripts and metadata from Antenna. You work with your new vendor to map your content structure to their system. You identify which content needs rewriting, translation, or removal.
Weeks 5–8: Content adaptation and new platform setup. You rewrite and optimize scripts. Your new vendor builds the guide framework and begins processing content. You create QR codes or distribution mechanisms. You set up analytics tracking. You train staff.
Weeks 9–10: Testing and launch prep. You run internal testing on the new platform. You validate that visitor flows work as expected. You prepare parallel operation: both systems active, visitors choose which they use (or are randomly assigned for A/B testing). You prepare rollback plans if the new system has issues.
Weeks 11–12: Parallel operation. Both systems run live. Antenna still works for visitors who choose it; new system is available for others. You gather feedback, monitor data, fix issues in real-time. Most visitor problems emerge here.
Weeks 13–14: Cutover and cleanup. Once confidence is high, you sunset the Antenna system. You stop supporting the old devices. You return hardware. You begin monitoring the new system for stability.
Weeks 15–16: Post-migration. You analyze data, gather staff feedback, document lessons learned. You plan content updates and enhancements based on real visitor data.
The timeline is flexible. Small museums with simple guides might compress this to 8 weeks. Large museums with complex content and high visitation might take 16–20 weeks. The key constraint is usually content adaptation, not technology.
Parallel operation is strongly recommended. It adds temporary cost—you're paying two vendors for 2–3 months—but it eliminates the risk of a failed launch. If the new system has problems, visitors can still use the old one while you fix things. The cost is worth it.
What Changes (And What Doesn't)
Here's what you'll notice after switching from Antenna to a modern platform:
What changes dramatically:
- Production speed. Scripts go from 4–8 weeks to live in 1–2 weeks (or instant with AI generation).
- Language support. Adding a language goes from 3–4 months and significant cost to 2–3 weeks with AI, or instant for AI-generated audio.
- Hardware management. Gone. You're not checking devices in and out, managing batteries, replacing broken screens, or storing equipment anymore.
- Update speed. Changing a single sentence now takes minutes instead of scheduling a new production cycle.
- Device costs. Without hardware to buy, your annual costs are typically 60–80% lower.
- Data access. Real analytics about visitor behavior—which stops they visit, how long they spend, what they engage with—instead of vague usage statistics.
What stays familiar:
- Content creation. You still write scripts based on your collections and interpretation goals. The core intellectual work doesn't change.
- Visitor experience. The audio guide experience is similar—visitors scan or click, they hear audio, they move to the next stop.
- Staff workflows. Your museum staff still owns the content and interpretation. You're not outsourcing curatorial decisions.
- Measurement and assessment. You still care about visitor engagement, educational impact, and whether the guide serves your institution's goals.
What improves:
- Operations integration. Most modern platforms integrate with ticketing, retail, and email systems. Antenna typically doesn't. This is a major shift if you use ticketing data.
- Accessibility. Newer platforms have better subtitle/caption support, adjustable playback speeds, and accessibility features. Antenna's accessibility is functional but basic.
- Support model. Most modern vendors offer faster, more responsive support. Antenna's support is competent but can feel bureaucratic for small changes.
The biggest change is philosophical: you're moving from hardware-as-infrastructure to software-as-service. You stop owning and managing equipment. You start accessing a platform. This feels like a constraint loss until you realize it's actually a freedom gain—your team can focus on content and visitor experience instead of device logistics.
If you're evaluating where to go, here are the key differences:
Cost structure: Antenna is typically €8,000–15,000 annually per 100 visitors in peak season, plus hardware costs. A modern QR-code-plus-cloud platform is €300–800 monthly (€3,600–9,600 annually) with zero hardware. AI-powered platforms like Musa are typically €600–1,500 monthly depending on usage, but include unlimited multilingual content generation.
Content production: Antenna owns the process and timeline. Modern platforms mostly get out of the way—you own the timeline. AI platforms accelerate it further.
Data and analytics: Antenna provides basic usage counts. Modern platforms provide visitor journey mapping, stop-level engagement, dwell times, and conversion correlations. This data is actually useful for exhibition design and operations.
Flexibility: Antenna hardware is fixed—if you want new features, you wait for a device release. Software platforms iterate constantly. You can test new ideas in weeks.
Vendor dependency: Antenna is proprietary and expensive to leave. Most modern vendors use open standards (QR codes, web standards, cloud infrastructure), making future switching cheaper.
Staff time: Antenna requires ongoing device management and administrative overhead. Modern platforms require content management only.
Moving Forward
Switching from Antenna is a legitimate change. Most museums who make this move report higher satisfaction, lower costs, and faster content workflows within 6 months of cutover.
The migration itself is a project—8–16 weeks depending on complexity. It requires planning, clear contract management, and realistic content adaptation. But it's not a technical problem. It's a project management problem, and museums solve these all the time.
At Musa, we've worked with Antenna customers specifically because we understand what you're migrating from. We've built the platform to make the transition easier: instant audio generation so you're not re-recording content, QR code distribution that requires no hardware, built-in multilingual support, and analytics that actually inform exhibition decisions. We handle parallel operation, content mapping, and staff training as part of the migration project.
