All this guesswork can now be eliminated by using a Weatronics Dual receiver. This unit records the values of the signals received from its two antennae and that data can be downloaded onto the PC or laptop after the flight . So, the answer is simple; try your various aerials as, say, no 2 in the DR and see what the receiver records for each aerial type. This device is an incredibly valuable and powerful tool for REALLY finding out what is going on in our radio systems.

The Weatronics looks pretty awesome, solves many problems in one shot, but it's $600 or so, and I don't THINK it comes on 72mhz yet...but I think there are a lot of guys who don't want to throw another $600 into their jet, or their credit card companies won't LET them throw another $600 into their jet!
I have a question about the shortly 7" deans base-loaded antenna. It's very convenient, but I have been unwilling to try it in a larger plane, because of fears about the range. Valid fears, or no?
