Diamond Editorial Review
The Diamond Antenna SRH77CA is a great performer with a +6dB gain on the 2-meter band. It is compatible with many radios including Yaesu, TYT MD-390, VHF/UHF radios such as Yanton T65UV, and Baofeng UV5RA using the SRJ77CA adapter. Unlike other antennas, it is not efficient for scanning the 800-900 MHz range. One reviewer had poor SWR on the 2-meter band resulting in impairment to their equipment. However, overall, the majority of reviewers enjoyed the reception and performance of the antenna, with some claiming a much better range than their previous antennas, and good SWR across the 2m band and 440.
