UHF Offset, Dual Dipole Array, 2 x 5dBd, 400-520 MHz

The RFI range of UHF dipole arrays provide expanded bandwidth, high power ratings and unequalled performance in gain, pattern and intermodulation performance.

Ever increasing costs and site density requirements are reducing availability of antenna positions on prime sites. In order to reduce the overall number of antennas the RFI dipole array series provides system engineers and site owners with a flexible solution to reduce antenna numbers.

OA2020-67-P Features:

The UHF Offset arrays feature the same solid construction as the BA and EA series. The array utilizes an internal phasing harness in PTFE based double screened coaxial cable with polyethylene jacket to aid waterproofing and resist bird attack.

The OA Series have slightly more than 170° horizontal beamwidth, thus everything in front of the antenna is given coverage. This eliminates the possibility of fading at the extremities of the target coverage area. The level of radiation at the rear of the antenna is 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 include extensive sidelobe suppression, null fill and a power input level of 500 Watts continuous.

• Operate over entire 400-520 MHz band
• Inverted mounting version available
• Hermetically sealed internal phasing harness
• Industry-leading PIM ratings (-150dBc) providing low IM and low noise characteristics for optimum performance

(1) Ruggedized black powder coated finish (aids in ice shedding for extreme conditions) is available on all aluminum arrays
(2) OA20 and OA40 series may be optionally supplied in all welded 316 Marine Grade Stainless steel. Dimensions vary slightly
