If long metal push rod wires are in use keep the antenae as far away from them as is reasonable. Wood plastic and most other push rods won't interfere with the reception. Newer radios are likely less prone to this than older systems but why tempt fate. On fixed wings and wings that contain the radio gear such as profiles the antenae is often routed towards the wing tip sometimes in the wing in a plastic tube. A small button or piece of control horn can be used to "keep" the wire just before it exits the fuse ( as shown previously) thus preventing its being pulled out of the actual reciever. I use a rubber band or slip situation at the antenae's end. search antenae here and I bet you get a lot of tips.
