Help,



Anyone have any good info on how far a comm antenna should be from the pilot?



My current antenna in mounted in the rudder, and the coaxial is cracked inside the rudder.



Trying to find another place to mount an antenna without going external and without cutting into the rudder.



This is in a Silent-IN, and there is carbon in the tail from about the back third of the wing all the way back.



The area around the pilot is glass, and also there is a possibility of mounting behind my seat back.



Considering using the Becker flexible antenna that appears to be made from coaxial. Anyone have any experience with this antenna?



Thanks

As Bob says, fix it properly. Other parts of the fuselage that will block emissions in some directions are not RF opaque. A decent glider shop should be able to help you here. The important thing is to make sure you really know the cable/antenna is bad before you start cutting. When you say rudder do you you mean vertical tail fin? If its a rudder hinge mount you (or your A&P) may be able to just take the rudder off to get access.
