I ran a test to see what type of meter would give the most accurate SWR readings on my Uniden 980SSB radio running on a Solarcon A-99 antenna with almost 100 feet of coax. For the test, I used a vintage Micronta 3 Range Power / SWR Tester, a NANO VNA, and the built in SWR meter of the ATU-100 antenna tuner.
