Abstract :
A small-diameter tubular test chamber lined with lossy material (ferrite) has been developed for indoor tuning and testing of the base-isolation and impedance-correcting networks of a VHF whip antenna covering the frequency band from 30 to 76 MHz. Results of experimental evaluation of the chamber which attest to its usefulness in production tuning, power testing, and field maintenance servicing of the antenna assembly are presented.
