Genuine Products
Genuine Nagoya antenna from a trusted company like Btech. Everything I buy from Btech is genuine and performs the way it should. I noticed the reception improvement immediately from my Nagoya purchase. Great antenna value and reasonable pricing from an economic perspective, performance value unquestionable! Great design and compatibility with for all my HT needs.

Works on 1.25m, which is awesome!
Haven't used it much on 2m and 70cm yet but it *works* on 1.25m and that's what I was looking for so, score! Worked better on a Baofeng K6 than on a Tidradio TD-H9 but it worked at all on the H9, which even a tri-band adjustable Smiley didn't.

Nice antenna, except for one thing. Screwing it down, does not make contact with the radio.
Love this antenna, except for one thing. Screwing it down, even with the rubber grommet that they provide does not make contact with the radio. You would think they would provide different options or different thicknesses of rubber to ensure clean contact with the radio. It leaves about an 8th to 3/16 gap between the bottom of the antenna and the top of the radio base. While the antenna is secure, it is not a very good fit and looks sloppy. It does help receive signal better than a tactical antenna that I have. So for that, it is still worth the buy. I would hope that the manufacturer would come up with a better way to match different radios. The radio that I'm using this for is a.BAOFENG 5RM.

Amazing!!!
All I can say is, these things are amazing! I already had some 15’ inch whips from various other brands, and didn’t really expect much better performance. I bought 3 of the 17 inch Tri-band, and these things completely blew all my other antennas out of the water. I can’t say enough! I am picking up signals I never picked up inside my house.

nao vou dizer que o modelo nao presta mas sim a que veio pode ter chegado ao destino defeituosa
nao atendeu em nada, coloquei no radio e ele ficou mudo, a que veio no radio é melhor em muito a essa NA 320a que prometia ser bem melhor.
