Default Antenna

I think I've read somewhere (perhaps here) that the out-of-the-box length of a receiver antenna for a 72Mhz radio is 31 inches. Is that correct? I think a kitten ate some of mine.

The RX antenna should be 39.4 inches. That is the optimum 1/4 wave leingth for 72 MHZ. Anything shorter than that will hurt your range.

One meter (39.375 in) + or - 1/4 inch and I have NEVER seen two of identical length, so it can't be that critical.

Thanks guys. I thought mine looked short, and after seeing the goofy look on the kitten's face, I thought I better measure it. It is right at 29 inches from receiver case to tip. Guess I will solder a piece of good 22 gauge wire on it to make it the proper length and drown the kitten.
