Review on 💎 Diamond RH77CA Dual-Band High Gain Handheld Antenna - 144/440 MHz. Rx: 120~900 MHz. by Eduardo Reyes

I've had this antenna for a little over a year now and use it primarily with a GRECOM (now Whistler) PSR-800 scanner as a replacement for the serial antenna. Although the antenna receives better than the standard antenna, it has one major disadvantage; That means the BNC connector doesn't have enough "notch" on the end for the antenna to attach to the antenna socket. The antenna detaches without even exerting any force on the connector. Other BNC connectors work better, so this may be a feature of the PSR-800's BNC connector. If it hadn't been for that, it would have been four or five stars.
