HI
Yes they are REALLY fiddly I have managed to pull the wire out of the plug on my transponder when trying to switch it over quickly.
I have now just put a small piece of heatshrink over the end of the plastic part of the plug and going onto the wires, so the little bit you can manage to grab of the wire when pulled it is actually pulling the plug and not so much on the wire.
It's great not having an aerial but something had to give
LMAO
