I have a foldable TwayRdio antenna in camo, I thought it would be a joke as it is long, too long, but I tested the SWR's and they are under 1.5:1 on all FRS/GMRS frequencies! The reception is way better than the 701-C, 771-C, and the stock (I have all of them). I cannot seem to find anyone to talk to for testing in my area, but when I do, I will use all my antennas and report back. I am leery about using the stock one or the 701-C anymore because the SWR is over 3 on both of those across all of the GMRS and FRS frequencies.
I Did by an external antenna and mounted it on my car, just waiting for the SMA connectors to come in. I bought the Browning antenna and mounted it to my fender!! Once that gets hooked up I hope to actually be heard! Also, I cannot access the one repeater in my area because my programming cable does not work, I have a new one coming (should be here tonight). I have no clue what I am doing, but should be hitting repeaters soon.
