    Radio Shack SWR F/S Meter 3-30 MHz Ham CB 21-533

    This Radio Shack SWR Field Strength Meter PN 21-533 is a classic, tried and true design and has been around for decades. It is designed to handle up to 1000 watts, although I have never passed more than 100 watts through mine. This meter will allow you to measure forward and reflected transmitted RF power. Install the sense antenna and you can also use it to measure field strength. Nice feature. I've used various versions of this Radio Shack SWR F/S meter for decades. Basic, simple, functional. It is well constructed and will take moderate abuse. Every amateur radio operator, and CB'er for that matter should own one.

    Excellent piece of test equipment.

    Perfect meter for testing power output of small portable radios. Especially effective at verifying radio power out and antenna health.
