Tom,
I installed a WX950 on an IVP and it works fine. The antenna is located 
roughly between the gear legs, and the base of the antenna bolted to the bare 
carbon (no paint under the antenna). The only quirk is that we get some noise 
(a streak of false lighting indications) when the hydraulic pump runs. There 
is a "suppression" input on the stormscope (I'm not sure if the -500 has it, 
as I don't have the manual handy.) which, when grounded, causes the system to 
ignore any signals. It was intended to be connected to a transmitter key-line 
supress interferance during transmit. My plan was to put a small control 
relay in the hydraulic pump circuit to ground the suppression input during 
pump operation. The owner wasn't concerned about it, however, so we never 
installed it.
