Works well for my purpose review by Jack on 2/10/2024

I installed this antenna on my balcony using a Melowave NMO mag mount (from BTWR, highly recommended), which is attached to the metal railing of the balcony. The purpose was to reduce the profile relative to a previously installed 5/8 over 5/8 GMRS antenna (also from BTWR), which works great (flat 1.01:1 SWR across GMRS), but is "too large" for someone's liking.

Out of the box, this shorter Tram antenna had an SWR of about 1.05:1 on 462 MHz and about 2:1 on 467 MHz (in my particular install conditions; others may vary). I might consider trimming this antenna a little bit in the future, but it already works well for a small GMRS repeater I own, because SWR is more important for TX (462 MHz) than for RX (467 MHz). So I am already happy with this antenna.

High quality antenna. It works great in my medium sized SUV. Cable length was more than adequate to reach the front seat area. I am very happy with the antenna as well as Buy Two Way Radios as a whole.
