The SPQ-230 HF spiral antennas are designed for installations where space is at a premium and the communication requirement is for operation on several circuits simultaneously. The antennas are four arm spirals that are fed with a four port hybrid designed specifically to provide two short range and two medium range patterns simultaneously. The relatively small installation area and multifunctional operational capability makes these antennas ideally suited for congested antenna fields or sites where space is severely limited. The antenna is protected under US Patent 5189434.
Features:
The SPQ-230 operates as four (4) Separate antennas integrated into one structure. All inputs are isolated from each other permitting full duplex operations on two separate circuits and a medium range skywave circuit simultaneously or three half duplex and one receive only circuit. The spiral is a four arm equiangular design that is would on a pyramidal structure formed by a central tower and four catenaries. The catenaries are dielectric with prepositioned element attachment clamps. The elements are constructed from jacketed cables that provide protection from the environment. The elements are terminated in resistive loads. The tower is a bolted aluminum structure.
Four independent LPV-1215 antennas arranged in a rosette configuration about a single tower.
