RE: Whip Antenna
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.
