The SG-7200 is a high-gain, dual-band mobile antenna designed for VHF (144 MHz) and UHF (430 MHz) amateur radio operation. Delivering 3.0/6.0 dBi gain and capable of handling up to 50W–150W of power, it is a popular, cost-effective choice for improving vehicle and base station range.
Key Features
Dual-Band Utility: Eliminates the need for two separate antennas by covering both popular bands in a single whip.
Radialless Design: Does not require a traditional ground plane setup to function properly, making it very forgiving for a variety of vehicular installations (such as hatchbacks, trunk lids, or lip mounts).
Long-Range Performance: High-dBi gain effectively cuts through signal dropouts caused by terrain or distance, vastly improving transmit/receive clarity to and from repeaters.
