Thread: Stryker Base with HY Gain Super Penatator spt 500

    Default Stryker Base with HY Gain Super Penatator spt 500

    Problem is this When I turn on radio I get not any static or receive anything. I moved my coax around and I can get it to receive. So I thought loose cable or defect at connector. so I tightened it all and now couldn't get anything unless I unscrew the coax ground then I receive. The ground on the antenna is connected to a earth ground copper rod 8' What else can I do. Is it a radio problem or antenna. I did connect my 2 meter antenna to the radio and it acted the same, center lead in I get static and connect outer sleeve and dead. This antenna is working good on my 2 meter radio.
    Thank You

    Sounds like you could have a short somewhere on the coax lead.
    It might be worthwhile opening the radio and inspecting the coax socket too...

    That can happen if the center conductor of the coax is broken somewhere. When you remove the shield connection, the in-tact portion of the center conductor capacitively couples to the jacket which acts as an antenna. Take a continuity tester to the center conductor and see of there is DC conductivity.
