AS-48951 Omnidirectional Antenna

The polarization is 45° slant linear, allowing reception of right-hand circular, left-hand circular, vertically, and horizontally polarized signals from a single connector.

The AS-48951 Antenna is ideally suited to applications where size, weight, and, with an optional heavy-duty radome, rugged construction are needed to provide broad frequency reception.

Features:

Small Physical Size
Lightweight Rugged Constructionn
Full 0.5 to 18 GHz Coverage
Simultaneous Horizontal, Vertical, RHC, LHC Polarization
