I currently have a couple of BTech GMRS-V1s. I bought them for emergencies but sometimes use them on trips and outings. I'd like to increase the reception and range a little so I'm guessing a better antenna will help somewhat. BaoFeng recomends the Nagoya NA-701C for the GMRS-V1, but I would think the Nagoya NA-771 would be better overall because it's almost twice as long. The specs for each are almost the same, but I'm not really a tech guy, so comparing the numbers doesn't help me. Any thoughts? Any other antennas I should look at? Thanks.
