758-A

The General Radio 758-A Wavemeter was introduced in Catalog K2 (1942) and remained available through Catalog N (1954).

The Type 758-A is a UHF absorption-type wavemeter with direct reading from 5 MHz to 400 MHz in a single band. This wide range is possible by varying both capacitance and inductance simultaneously.

The 758-A uses a flashlight lamp as a resonance indicator, as little as 2 watts of RF will give an indication. The instrument case is hexagonal so that the wavemeter pickup can be oriented in one of six positions.
