UHF Offset Dipole Array 400-520 MHz - 9 dBd
The OA40-67 Series arrays feature the same solid construction as the BA and EA series. These arrays utilise an internal phasing harness using PIM rated PTFE based coaxial cable as well as custom dipole design to improve weatherproofing and resist bird attack. The OA Series have approximately 180° horizontal beamwidth, thus everything in front of the antenna is given coverage, providing extra gain in front with coverage at the rear of the antenna at approximately unity gain. As would be expected from a cardioid array, the vertical beamwidth is slightly greater than its BA omnidirectional or EA elliptical pattern counterparts. These antennas are also offered with -3°, -5° or -8° of beamtilt (OA40 only), and all include extensive side lobe suppression, null fill and a power input level of 500 Watts continuous.
Features:
- 4.3-10 high performance connector
- Operate over entire 330-420MHz or 400-520 MHz bands
- Inverted mounting version available
- 5 dBd or 9 dBd gain versions available
- Hermetically sealed internal phasing harness
Industry leading PIM ratings (-150dBc) providing low IM and low noise characteristics for optimum performance (1) Factory pre-set downtilt may be specified on OA40 series antennas using model no. trailer - T3, -T5 or -T8 (2) Ruggedised black powder coated finish (aids in ice shedding for extreme conditions) is available on all aluminium arrays (3) OA20 and OA40 series may be optionally supplied in all welded 316 Marine Grade Stainless steel. Dimensions vary slightly.
