Antennatuner nightmare

How on earth could there be water in the tuner? It is sealed! It's my worst nightmare.....
Strange enough I didn't have any issues till now. It was still working a few days ago. I just dismantled the antenna and heard water in the tuner. I thought I better let it out.
Hopefully there is no damage, although I doubt it...


  1. temperature variation cause a rigid seal to flex and crack?

  2. Had similar issue back in the 90s. Rain water coming in the shack via gravity, due to a loose antenna coaxial connection ...

  3. Hi Bas

    I have also recently found water in my RX active loop box.
    Not as much as you had but it had been there for a while and corroded a couple of components I have change since!

    It is not very how the water pass through.
    Good luck

  4. water commming in from the external coax you will need to replace the coax as it is filled with water. the antenna tuner was adapting the impedance so you did not noticed it.

  5. Hoi Bas. Dat is wel effe schrikken, al dat water in je tuner. Kan een hoop oorzaken zijn. Ik hoop dat hij goed opdroogt en geen defecten heeft ondervonden van deze zwemlessen. Ik ben benieuwd wat de oorzaak is. 73 Hans, PE1BVQ
