Probably the best antenna on the market, I measured an average of 1.25-1.75:1 at 440 & 462 and 1.75-2.0:1 at 140 & 155 on 4 of these out of the 5 I've bought so far!
I had one that was high, 3.5-4.5:1 I trimmed about 1.25" off and recapped it with gorilla glue and a screw cover from home depot, now it's averaging 1.1-1.25:1 at 440 & 462, and 1.5-1.75:1 at 140 & 155
Using these on the following radios; TYT MD2017, TYT MD680, TYT TH-UV8200, Radioddity GD-55+ and a simplex repeater via Retevis RT1. I get anything from 2.5-7mi out of these in Western PA, which has both lots of hills/trees and urban obstructions. Without these antennas, at best I was getting 1-3mi so I've gained more that double in most regards my ability to reach out.
