As with TR1 I like putting the plastic tube down the fuselage and leaving a small amount sticking outside of the plane!!! I have never had any range checking problem with this!

As with the WSDEANS antenna...I have one, and have tried to use it on two different balsa planes and never could get it to range check!!!! But the helicopter guy's use them and they work great!!!

Big disclaimer here...I am not an antenna expert but in the Old days of CB (1971 to 1973) before the trucker's when CB was alot of fun...the big thing for getting range was the "Ground Plane". The taller the antenna the more ground plane area you had to have!!!!

To put this in perspective maybe the heli guy's have more metal to reflect the signal than the balsa guy's do?

God I am getting old!!!!
