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

The RH77CA diamond antenna is essential for your scanner to greatly improve the reception of high frequency VHF transmissions such as: fire brigade/ambulance, public safety, rail transport, civil and military air! I use RH77CA Diamond antennas on both of my scanners to greatly improve high range transmission. You will discover many frequencies around you that you didn't even know existed! Of course I knew, I found a total of fourteen different Houston ARTCC frequencies in my area that I didn't even know were being used!
