Posted: Wed May 09, 2007 7:11 am Post subject: Zanon XRX antenna position |
|
|
I just purchased the Zaon XRX Portable Collision Avoidance System (PCAS) to add traffic awareness to my cockpit. With it connected to my Garmin 396 I want to move it (with its built in antenna) away from the recommended glareshield mounting. For those of you with experience my question is will the antenna work with it located other places such as below the glare shield or behind my tip-up roll bar or on my lap (as long as it is 6" from any obstacle)? It is a hard thing to test because it does not activate until you have climbed 200 feet and there must be another airplane nearby. I tried Zaon. They just moved their operation and, consequently, their technical service is down for a while.

My low end MRX with its swivel antenna needs a clear view around the
aircraft. It seems to be easy to blank the antenna or fool the range if
it gets a weak signal. Similarly it works better if the antenna is
vertical rather than almost vertical. Since it doesn't give azimuth
info, the MRX only needs the one antenna and a remote antenna cable
extension is available. I think the external antenna was as much money
as the MRX but I suspect it would enhance performance quite a bit.
Anyone try a homemade antenna?? My manual also says it needs a 200 foot
altitude change to be fully operational (I forget the details) but it
displays traffic in the circuit just fine even if I turn it on in my car
or in the open hangar. I always check it before pulling onto the runway.
For $400. I consider it almost essential for safe flight now. I'd be
interested in hearing how useful the azimuth info is on the XRX.

I own the MRX as well and agree that it's essential for safe flight in high traffic areas.
I am building the MRX into the panel with the Zaon installation kit (couldn't be bothered bending the aluminum myself for the $30 they're asking).
The external antenna can be any transponder antenna like the $12 TED antennas that are for sale on eBay. Don't install the PCAS antenna too close to the transponder antenna, otherwise you'll need an expensive attenuator.
I don't know if the XRX has the capabilities for external antennas, but that would be the way to go.

The XRX antenna is much larger (diameter) as it is a special directional
antenna. A remote option is supposedly in the works from Vaon, but the
prototype (at) SNF looked pretty ugly. There are no (visible) remote antenna
ports on a XRX.
