HT Antenna

(1/3) > >>

Matt285:
So I bought a fake 'Nagoya' HT antenna. It is approx 14.5'' long compared to my stock antenna which is approx 8'' in length. However the shorter stock antenna out performs the new longer one? I decided to dissect it this morning thinking for sure there a broken soldering joint etc. No signs of anything. One thing I noticed is that the ground is used for the radiator. I would have thought the center feed line would be used for this? I just don't understand how something this simple could be screwed up. It would seem to me that you would find a length of wire that is resonant on 2m/440 and attach it.

Matt285:
Correction. After some continuity testing I've found that the center conductor is used. Still don't know why this thing performs so terrible though.

Because it is made in China?

Matt285:
Ha, yes it is made in China, but it's a very simple concept. The construction actually wasn't too bad inside. I'm thinking that it's possible a improper measurement and that High VSWR power fold-back may be a factor.

Matt285:
So, as said I dissected the antenna and broke it down to the soldering points. Everything looked OK. I soldered the connections in a couple of different new points of contact and glued back together. Did a test of 15 repeaters on 2m/440 and the stock antenna still outperformed the knock off longer antenna. Conclusion- Buy name brand from reputable sources.... Still can't quite explain though?
