Extend the range of your Proxima wireless system with the WA-AS1 external antenna.
Wireless base stations are often mounted inside steel control cabinets, which block radio signals and weaken coverage across a Proxima mesh network. The Produal WA-AS1 is an external antenna and extension cable for the WBU base station, rated -40 to 85 °C, that moves the antenna outside the cabinet to restore signal strength.

What the WA-AS1 antenna is used for
A steel control cabinet acts as a shield against radio signals, which is exactly the problem when a WBU base station has to be mounted inside one for protection or convenience. The WA-AS1 connects to the WBU with an extension cable and sits outside the cabinet, giving the base station's 2.4 GHz signal a clear path to the surrounding Proxima mesh transmitters.
When to add the WA-AS1
- The WBU base station is mounted inside a metal panel or plant room enclosure.
- Signal strength readings to some WTR transmitters on the mesh are weak or intermittent.
- The base station has to be sited away from the best radio position for other practical reasons, such as cable routing.
- The installation is outdoors or in a location exposed to a wide temperature swing, within the antenna's -40 to 85 °C rating.
It's compatible with the Produal Proxima MESH wireless network as used across the Proxima 2.4 GHz wireless mesh components. For the transmitters and base station it connects to, see that page; for the wider wireless retrofit picture, see wireless HVAC transmitters.
FAQ
Common questions
Why do I need an external antenna for a wireless HVAC base station?
A steel control cabinet blocks or badly attenuates the 2.4 GHz radio signal a WBU base station needs to reach its mesh transmitters. The WA-AS1 moves the antenna outside the cabinet on an extension cable, restoring the coverage the metal enclosure would otherwise block.
Is the WA-AS1 compatible with any Proxima wireless system?
Yes, it's designed specifically for the Produal Proxima WBU base unit and the wider Proxima MESH network, so it works with any WTR or WTR-IM transmitters already installed on that mesh without further configuration.
Can the WA-AS1 antenna be used outdoors?
It's rated for -40 to 85 °C, which covers most outdoor exposure, but the mounting and cable routing should suit the specific location. Tell us the installation environment, indoor plant room or outdoor wall, and we'll confirm the right mounting accessories.
How do I know if I need the WA-AS1 antenna extension?
If the WBU base station sits inside a steel cabinet or plant room and nearby WTR transmitters show weak or dropping signal, that's the typical sign. Since the base station location is often fixed by other constraints, the antenna extension is usually simpler than relocating the whole unit.
