Got to get into this before everyone finally agrees on something. Not really an expert on antennas and such but I was designing them for mobile phones when Seattle had only two channels and the phone just fit in a Sampsonite briefcase with the aluminum trim shunt fed as the antenna. I still use my Boonton 250A RX meter to to trim antennas.
About all I fly now are DLGs with carbon booms. No big deal if the pod is Kevlar or glass or a combination of both. The RX and Bat pack and servos in the pod form the counterpoise portion of the antenna and the RX antenna goes through the carbon boom and is secured as it exits the end of the boom. The boom is capacitively coupled to the antenna and you end up with an acceptable but low Q antenna system. It might not work at super long range on a X-country model but is good enough to get you to the top of any of the hills around the Poway IHLGF site. If the Pod were a carbon weave or one of the combination carbon and glass or carbon and Kevlar It gets iffy for anything other than indoor or other really close in flying models. -- Dick Barker Port Angeles, WA - Turning HLG Around - >Larry Taylor KF6JBG >>"Simon Van Leeuwen" <[EMAIL PROTECTED]> >>>"James V.
