    What is the easiest way to check SWR meters.
    I have a RIGEXPERT Model 54 Antenna Analyzer my thought is to take a reading of a dummy load and or various antennas with the same coax length and compare the swr reading of the analyzer against the swr meter.
    Should be about the same, yes/no

    Thank you

    Do you have a UHF Tee (or other Tee) and two dummy loads?

    You can make a 2:1 mismatch by hooking up two loads at the same time with the tee ...

    That might be the better test. See if they both indicate near a 2:1 mismatch.

    I just compared my SWR meter to a RigExpert this morning.
    As a rough comparison, we scanned the antenna's band with the RigExpert and then I tried the SWR meter at some of the peak and trough frequencies and compared to RigExpert spot measurements at the same frequencies.
    My 1978 Heathkit IM-4190 came remarkably close to the rig expert.
    You can see my thread about it here:

    (But, if your SWR meter is a good one, it should have calibration directions in a service manual somewhere.)
