DESCRIPTION AND USE ELECTRO-METRICS
MODEL RVR-30M VERTICAL ANTENNA
1.0 Introduction
The Model RVR-30M Vertical Antenna performs electric field measurements from 9 kHz
to 30 MHz. A ten position rotary switch is used to switch in the appropriate matching network
for the frequency selected. Though specifically designed for use with the Electro-Metrics Model
EMC-30 Interference Analyzer, it can be used with any equivalent 50-ohm receiver/analyzer
being designed and calibrated for use in a 50-ohm system.
The Model RVR-30M is designed for use in conjunction with the Model GPA-30
Counterpoise, Model TRI-136 Tripod, and Model CAC-30 Coaxial Cable.
The bottom of the base has a 5/8-20 threaded receptacle for mounting to the Model TRI-
136 Tripod.
