Re: SSB Ground

Joerg,

In my experience with SSB, Matt is exactly correct about multiple nearby masts.

Also, I looked closely at your photo. It is my understanding that a marine 4" stand-off" antenna mount must be used to hold the SSB antenna a minimum of 4" from other metal parts. In the Amel SM and 54, Amel used these to "stand-off" from the life rail. I believe I see the stand-off near the top of the Simpson Davits. I also note two things:
  1. The Simpson Davits represent a very large piece of metal. Maybe the stand-off separation should be greater. An HF/SSB expert should comment here.
  2. The separation was not visible in your photo at the base. Is it also 4"?

One other big issue is trying to transmit from a marina. All the masts adversely affect transmission. You’ll have to leave the marina to get an accurate assessment .

Thank you, Herbert.  I will clean the dynaplates next.  I have had the tuner and the transmitter tested twice and I do hear the tuner clicking.  My antenna is installed next to the davits but I asked the manufacturer of the antenna about that and they said it was fine.  I will try to swing the mizzen boom away, though.

Daniel.  I have removed that extra wire as well.  The control wire from the transmitter to the tuner carries ground as well so the additional wire Amel installed is not necessary and may be harmful as you say.

Following the link to the SSB goodies you sent, I see the SSB grounding paint. Someone told me to paint the bottom of the Lazarette with that paint and connect it to the tuner with copper tape.  Theoretically this should work but has anyone tried it?
