Cut my antenna in half.....


I accidently cut the antenna of my futaba reciever in half ? Does anyone know of any way to splice the antenna or any other fix? Thanks for any ideas! The receiver is an older one. It is a FP-R127df Dual conversion 7 channel unit.

I fly DLG's and power planes... There is a guy who uses guitar strings for antennas and imbeds them in the wing. This way each wing has its own. There is a connector on the stub protuding from the receiver and one on the wire in the wing.. As long as the length is the same your good.. Here is the link: there are a couple posts (from Buddy Roos) with pics and description / how to: thread.https://www.rcgroups.com/forums/show...504554&page=10

Worth a try since it's already snipped.

Yeah, so when we're about to do the same thing, we can say "Hey, didn't shamrock1990 do this on the forums, and cut his antenna in half? I'd better not do that."

Yes, my mind does work like that. No, they haven't institutionalized me yet.

I'd solder splice it...then I would do a very good range check...
I solder splice by un twisting the wires so it looks like a hand held fan..both ends..then put the two fans together (rounded sides) Or so it looks like inter laced fingers..twist and solder,,,if it's solid core wire make to small hooks and solder together....

If you have all the pieces just solder it back together. You could also replace the whole thing with another piece of stranded wire. As long as the total length is 39 to 41 inches, you should be good to go.

AFAIK you can pretty much make/splice/bodge an rx antenna from anything conductive, a bit of plastic coated copper wire from some domestic flex will do fine, just strip the plastic from the rx antenna and the flex, then twist the ends together. Run thin solder over it and cover the lot with some heat shrink tubing and you're done. Then just cut the other end of the flex off so that the whole thing is about 40" long.

splice it


Don't do anything complicated, strip the wires back a minimal amount on each side, 1/8" should do. Twist the wires tightly, don't fan them out. Tin each side with solder. Make sure the solder melts into all the strands well. There should be no globs of solder. Cut a piece of shrink tubing and slide over one side. Place the tinned wires touching side to side sort of like this ----====____ . Heat with the solder iron till the solder flows in both wires.

Let it cool. Slide the shrink tubing up and shrink it. You are done.

This only shortens the antenna by 1/8" which should be negligible at 72MHz.
