DB803M OMNI ANTENNAS 3dBd GAIN, 806-960 MHz |
![]() Broad Response - Three models of each antenna fulfill frequency requirements for conventional, trunked, paging and cellular communications. DB803Q Quad - Consists of four transmit or receive antennas, or in any combination, isolated by at least 25 dB each. Field proven in the US air-to-ground 849-851 and 894- 896 MHz frequencies (three Tx antennas with an Rx on top). Sturdy Construction - In addition to fiberglass radomes, the antennas have weather-resistant masts made of strong 6061-T6 aluminum alloy. Very Rugged - Both antennas resist winds to 200 mph (322 kph) with 0.5" (12.7 mm) , of icing. Engineered to Last - All metals used in radiator, feed and matching systems are copper or brass, which minimizes galvanic reaction and reduces intermodulation. Lightning Resistant - A DC ground is provided. Moisture Resistant - A removable drain plug is located at the top and bottom of each antenna. Ready to Install - DB365-OS Clamps and VAPOR-WRAP" are provided. Ordering Information Use model number for correct frequency. Dual antennas are also available, see table. Clamps are included. Order jumper cables separately, if desired. |
