The Antenna has a 2.1dBi gain at VHF frequencies and 4.5dBi gain at UHF frequencies. An antenna with 3dBi gain will have twice the received signal strength when compared to an antenna with 0dBi gain. Received signal strength and therefore range can be increased by raising the transmitter output power or in this case, using a higher gain antenna.
The Antenna Assembly includes an Upper and Lower Antenna section, the Antenna Base, and the Antenna Cable. Physical dimensions of the individual parts are Upper Antenna (17.25”), Lower Antenna (9”), Base height (1.5”), Base diameter (3.5”), and Antenna Cable (39.4” or 1 meter). Total height of the Antenna Assembly is 27.75”.
