    You have no ground if your swrs are over 3 across the board looks like you need to pull that bracket off and scrap the paint off to get a good ground.

    Copy that still sounds like a ground problem if swr are above 3 and the same on 1&40 also check your coax connections maybe one is bad or coax itself is bad.

    First off stop.

    Second get an external meter and test it.

    Third electrical ground is not rf ground.
