| Description: | The
AS-3226B/U VHF Dipole Antenna is a rugged, self-supporting
vertically polarized broadband antenna, covering the frequency range
of 30 to 88 MHz. This general purpose antenna can be used in
the "transmit" or "receive" mode. The antenna is designed for use under server environmental conditions encountered aboard naval ships. The antenna radiating elements are housed in a single-piece fibreglass radome with a fibreglass mounting flange. Over the entire frequency range, the AS-3226B/U antenna can handle the following input power: * 400 Watts average RF Power * 800 Watts Peak Envelope Power It has a VSWR of less than 3.5:1 over the 30-88 MHz band. The antenna has been qualified to MIL-S-901C for shock, MIL-STD-167 Type 1 vibration, and all the service conditions of MIL-E-16400. |
