Not sure if anyone mentioned this, but receiver sensitivity is a big deal as well. If you are blasting out but you can't hear a return call, that might be frustrating to say the least.
Thank you, I am considering the mentioned Nagoya NA-320A, and I also saw the Diamond Antenna Tri-Band HT SRH320A for over twice the price but about 4 inches shorter. I would need an adapter, which is no big deal. I will have to decide how much I want to sink into this purchase.
Any recommendations for a tri-band antenna that you have used on an HT? I have a Baofeng UV-17R Pro GPS and just discovered it will transmit on 1.25m (as well as 2m and 70cm). The original is the standard male SMA to female connection dual band antenna.
