For industrial UAVs and long-endurance fixed-wing platforms, the wireless link is often the weakest part of the whole system. Airframes, engines and payloads have improved very quickly, but if the video and data link drops, the mission is over. This is exactly the problem that Verolink was created to solve.
On AIRMOBI’s side, we integrate Verolink systems into long-range VTOL and fixed-wing UAVs every day. This article is a practical guide to help you pick the right Verolink model for your range, aircraft size and mission profile.
1. Verolink in a Nutshell
Verolink is a focused product line of long-range wireless video and data links for industrial UAVs and unmanned systems. The main family runs on the 1.4 GHz band with different RF power levels from 2 W up to 40 W, covering typical air-to-ground
line-of-sight distances from 60 km to around 300 km.
Instead of trying to cover every frequency and every application, Verolink keeps the lineup simple:
- Verolink P33 – 2 W, 1.4 GHz, up to ~60 km
- Verolink P37 – 5 W, 1.4 GHz, up to ~100 km
- Verolink P40 – 10 W, 1.4 GHz, up to ~150 km
- Verolink P43 – 20 W, 1.4 GHz, up to ~200 km
- Verolink P46 – 40 W, 1.4 GHz, up to ~300 km with repeater options
- Verolink T900 – 10 W, 900 MHz telemetry radio, up to ~200 km
All models share a common design philosophy: long-range TDD link, adaptive modulation, automatic retransmission, intelligent channel selection and
industrial-grade RF design.
You can find the official, always-up-to-date specs on Verolink’s Video Links page or download the Verolink Product Catalogue (PDF).
2. Start with Three Simple Questions
When we help customers select a Verolink system, we always start with three basic questions:
- What is your realistic mission range? (Not just “theoretical maximum”, but what you truly need.)
- How big is your aircraft and power budget? (Small VTOL vs. 5 m fixed-wing makes a big difference.)
- What is more critical for you: video, telemetry or both over one link?
Once these three points are clear, choosing a model from the Verolink lineup becomes much easier.
3. Quick Overview: Which Verolink for Which Mission?
Here is a simple “at a glance” guide that fits most use cases we see at AIRMOBI:
- Up to 60 km, light VTOL / small fixed-wing → Verolink P33
- Up to 100 km, everyday industrial flights → Verolink P37
- Up to 150 km, corridor & coastal missions → Verolink P40
- Up to 200 km, large VTOL & fixed-wing → Verolink P43
- Up to 300 km, extreme-range and repeater setups → Verolink P46
- Long-range telemetry / SCADA without video → Verolink T900 900 MHz telemetry radio
The sections below go into more detail on each model and where it fits best.
4. Verolink P33 – Compact Link for up to 60 km
Verolink P33 is the entry point into the Verolink family. It is a 2 W, 1.4 GHz TDD video/data link designed for missions up to roughly 60 km air-to-ground line of sight when paired with appropriate antennas.
When we recommend P33:
- Small and mid-size VTOL UAVs where weight and power are tight.
- Survey, mapping or inspection missions within a 20–40 km radius.
- Users moving up from hobby-grade links who want something industrial but still compact.
Typical pairing on AIRMOBI platforms:
- Entry-level long-endurance VTOL and small fixed-wing aircraft.
- Single HD video feed plus telemetry over one link.
If most of your flights are well below 60 km and your aircraft is not very large, P33 usually gives a good balance between performance, weight and cost.
5. Verolink P37 – The 100 km Workhorse
Verolink P37 steps up to 5 W RF power and is rated for around 100 km air-to-ground LOS with proper antenna setups. This is the “daily work” link for many industrial users.
Where P37 fits best:
- Powerline, pipeline, road and railway inspection along long corridors.
- Medium-size fixed-wing and VTOL aircraft with enough power budget for a 5 W system.
- Security patrol, perimeter surveillance and similar routine missions.
If your typical requirement is “we need a stable HD link somewhere between 40–80 km, but sometimes up to ~100 km”, P37 is usually the first model to look at.
6. Verolink P40 – 150 km for Long Corridor & Coastal Work
Verolink P40 is a 10 W, 1.4 GHz system targeted at missions up to roughly 150 km LOS. It keeps the same general architecture as P33/P37 but
adds more RF power and link margin for demanding corridors and coastal routes.
P40 is a strong candidate for:
- Long corridor inspection where the aircraft follows a powerline, pipeline or coastline for tens of kilometres.
- Coastal surveillance where ground stations may be limited and sea reflections can challenge the link.
- Larger VTOL platforms or 3–5 m fixed-wing UAVs that already carry heavier payloads.
Compared with P37, P40 gives more margin for difficult RF environments, higher link stability at long distances, and more comfort if your “100 km mission” sometimes becomes 130–140 km in practice.
7. Verolink P43 – Heavy-Duty Link for Large UAVs up to 200 km
Verolink P43 is a 20 W, 1.4 GHz system designed for large VTOL and fixed-wing UAVs operating out to about 200 km LOS. It uses industrial-grade FPGA and transceiver technology and supports high code rates with robust error correction and automatic retransmission.
Where we typically see P43:
- 5 m class fixed-wing UAVs with heavy payloads and long endurance.
- Gasoline or hybrid VTOL aircraft flying long inspection or patrol routes.
- Projects where link loss is unacceptable and extra RF margin is required by design.
If you are already in the “big aircraft, serious mission” category, P43 gives a realistic 150–200 km operational window with the right antenna system and installation.
8. Verolink P46 – 300 km & Repeater Topologies
For the most demanding long-range work, Verolink offers Verolink P46, a 40 W, 1.4 GHz link aimed at missions out to roughly 300 km LOS with suitable high-gain and tracking antennas.
P46 is usually considered when:
- Mission planners are working with very long coastal or desert corridors.
- There is a requirement for repeater or relay topologies between aircraft or ground sites.
- Large, fuel-powered platforms are already available and can support the higher power consumption.
In these projects, we always recommend direct discussion with Verolink engineers, as P46 installations often involve customised antennas, tracking systems and link planning. You can reach the Verolink team via Verolink.com.
9. Verolink T900 – 900 MHz Telemetry for Command & SCADA
While the P-series focuses on 1.4 GHz video and data, Verolink also offers the T900 – a 10 W, 900 MHz long-range telemetry radio for command, control and SCADA-style data. It is designed for up to around 200 km LOS in harsh environments where a robust, lower-frequency link is preferred.
Typical use cases:
- Redundant control link in parallel with a 1.4 GHz video link.
- Remote pump stations, sensors and infrastructure where wired connectivity is not realistic.
- Projects where video is less important than a reliable telemetry and control link.
For many large UAV projects, a P-series video/data link plus a T900 telemetry radio gives a very robust overall communication architecture.
10. Other Practical Points to Consider
Aircraft Size & Power Budget
Higher power links like P43 and P46 offer more range and link margin, but they also require more space, cooling and electrical power. Smaller VTOL aircraft usually pair better with P33 or P37; large fixed-wing or gasoline VTOL platforms can support P40 or P43 more easily.
Regulations & Licensing
All distances quoted for Verolink systems are typical line-of-sight values under good conditions and with suitable antennas. Actual performance always depends on local regulations, allowed power limits, terrain, antenna quality and installation. Before making a final decision, check what is permitted in your operating country.
Integration with Autopilots & Payloads
Verolink systems offer Ethernet and serial interfaces (such as RS-232, TTL, SBUS and others, model-dependent), so they can be integrated with Pixhawk-class autopilots, CUAV systems, gimbals and onboard computers. If you already use one of AIRMOBI’s VTOL or fixed-wing platforms, we can provide recommended wiring diagrams and tested configurations on request.
11. How AIRMOBI Can Help
AIRMOBI is not only a reseller of Verolink systems; we actually integrate these links into our own VTOL and fixed-wing UAV platforms, run flight tests and ship complete PNP/RTF solutions to customers worldwide. This gives us practical experience with antenna placement, power supply design, cooling and RF behaviour on different aircraft.
If you are unsure which Verolink model fits your project, you are welcome to contact us with a short description of:
- Your aircraft type (size, power system, VTOL or fixed-wing).
- Required mission range and typical flight profile.
- Video resolution and number of video streams.
- Any special requirements such as encryption, repeater operation or redundant links.
Based on that, we can recommend a suitable Verolink system and, if needed, a complete UAV platform and ground solution around it.
