GAM SSB Backstay Antenna

We just purchased the SSB backstay antenna from GAM for our iCon 802. Our backstay on our 46 foot sloop is split and runs about 15' from the deck to the fitting that joins the port and starboard lower back stays to the single upper backstay. The GAM is about 30' long. Has anyone attached the GAM to a similar split backstay configuration (upside Y shape) and if so how did you handle attaching the antenna to the fitting that joins the upper and lower backstays. All thoughts appreciated.

Re: GAM SSB Backstay Antenna

If the present configuration does not allow attachment, you can change it to upside V shape.

Re: GAM SSB Backstay Antenna

Doug, I would just run up one side, whichever side is the more direct run, and then up the rest. If you need to use a length of bungee to jump past something, that could work. Or you could go up a shroud instead of the backstay.

The idea is to get a more-or-less straight more-or-less vertical wire going up for the antenna, and the only reason you don't glue it onto the mast is because that would be a ground plane running right alongside it.

Even the ARRL goes on record saying that every boat is a different case, even "identical" twins because of small differences. Try hoisting the GAM in a couple of different ways, making some non-local contacts, checking SWR, and use what actually works best. It may very well not be what "theory" says "should" work best.

Re: GAM SSB Backstay Antenna

On my last boat, I used a GAM on my split backstay and worked fine. I fed the antenna up from one of the legs until it got to the connector plate. I then had to hoist someone up to the plate and they simply continued to feed the antenna around the plate and up the center portion of the stay. We zip tied it in place, making sure te had a zip tie on either side of the plate, and never had an issue with it.

Re: GAM SSB Backstay Antenna

Windward, Hellosailor and Celenoglu - thank you so much for your prompt replies. I will take all in consideration. I'll try Windwards first then fall back on the others. Thank you for taking the time to reply, it's greatly appreciated.
