Topic: Multipath distortion with WS-2902, GW-1000 etc

Most people will never have this problem, but I'm putting this out there for some poor soul in the future.

The path between my 2902 array and my GW-1000 goes through my carport. Well, it turns out that there are some "magic" spots that if I park my car there then my signal and wx data goes away. It's because the radio reflection off of the car can be out of phase and cancel the main signal.

Just tonight I returned from the store, and checking WU I saw my signal and data went away. Rebooting the GW-1000 did no good. But when I moved the GW-1000 just three inches everything started working again.

I may have to install an external antenna on the array to solve this for good. But at least I know what it is.

I have noticed through experimentation that there is definitely a degree of polarisation also at play in the transmitted signal as well no doubt complicated by reflections.
Future consoles/GW1000 would do extremely well if they added a small aerial connector to the back to allow an external antenna to be added to resolve these 'sensitivity' issues!
