DUAL EXPOSED DIPOLE ARRAY
The Dual Exposed Dipole Arrays are available in many different configurations. VHF, UHF or 700/800/900 MHz antennas can be combined into one mast. Antennas can be interchanged with our 840, 870, 880, 770 and 790 series antennas. Antennas can be customized to your applications. Antennas can be side or top mounted.
• Low VSWR version with maximum gain over specified frequency. • Ideal for applications where costs are calculated per antenna. • Heavy duty versions are available. • Some versions of antennas have an adjustable pattern for 3 dBd omnidirectional or 6 dBd offset coverage. |
