I picked a pair of these up from Amazon. I increased my range by over 50%
Stock antenn I was seeing -70 around 600 feet away and at 300 elevation. I just tested these I I got 2200 feet at the same elevation before hitting -70. I did not push it any further but it was teetering back and forth from -70 & -68 db. I think I could have hit 3000.
