Review on High-Quality Dual Band UV VHF/UHF Walkie Talkie Antennas by LUITON - 15.6-Inch Whip, SMA-F Connector (2 Pack) by Ham Channell

I bought this antenna for my Baofeng HT. I compared it to the included Baofeng rubber ducky and the aforementioned Diamond SRH-77. The equipment was an Agilent E5072A network analyzer and a copper sheet ground plane. The SWR was measured at 146 and 445 MHz: Baofeng was 2.0 and 3.0. Luiton NA-771 was 3.6 and 2.6. Diamond was 1.8 and 1.1. The resonance for the Luiton was at 124 MHz (SWR 1.2) and 429 MHz (SWR 1.3). If you need an antenna to operate on these frequencies and have an RPSMA connector, this is a nicely made antenna at a good price. I cannot confirm durability as I only tested the item electrically. However, this is not an improvement over the standard Baofeng ham radio. Return loss and SWR plots for each 100-500MHz antenna are included.
