Buried in the Stbd wing are two aerials (VHF Nav & TPX ) and two coax cables exiting into the fuselage. Both have lost their labels and are not connected. The Transponder aerial is now external mounted on the Stbd Servo inspection plate. I would like to re-instigate the internal aerial and need a way of finding out which cable goes to the transponder. Connecting up a transponder and using a signal meter is not an option because my transponder manufacturer is very insistence that a transponder is likely to be fried without the correct aerial being attached. If the Nav aerial has some different properties then I could eliminate and id the transponder aerial cable.
