Model 640H

The Model 640H monitoring antenna provides TCI’s 700-series spectrum monitoring systems vertical polarization coverage from 20 MHz to 6 GHz, and horizontal polarization coverage from 20 MHz to 3 GHz. (The 640H utilizes integrated antenna elements to provide broadband coverage.) Reception of vertically-polarized signals between 200 MHz and 6 GHz is provided by a bicone antenna element; and a shunt-fed antenna element provides coverage from 20 MHz to 200 MHz. Reception of horizontally-polarized signals between 500 MHz and 3 GHz is provided by a slot antenna element. A loop antenna element provides coverage from 20 MHz to 500 MHz. Switching between antenna elements is performed automatically by TCI’s 700-series spectrum monitoring systems based on the frequency being scanned.
