Dan and Tempest,
I much prefer the radar on a pole. My Furuno 1832 is mounted on a Kato pole some 9' above the deck. I selected this alternative after a great deal of research, and have been very happy with the results.
First, I wanted a radar which would discriminate well on objects relatively close to me (like buoys, dingys, other boats, pilings, etc.). A radar antenna mounted up high does better at longer distances, but sometimes misses things up close. Result: couldn't be happier. The combination of a pole mount and a true CRT green screen with a 24" radome picks up nearby things very well, including lobster pots and crab pots!!
Second, I researched the backstay alternative, but didn't like what I saw at the time. There were lots of reports of failures of the fittings, two of the most prominent manufacturers at the time were either going out of business or had serious problems, and I really didn't like the idea of hanging something on the backstay.
Re: interaction of the SSB and the radar, that's not a problem with the pole mount. I don't know for sure if it would/could be a problem with a backstay mount on a wire used for transmitting at HF frequencies, but it would make me nervous as you might just be too near a high voltage or high current point and cause some damage to the electronics inside the radome, or infuse enough RF into the radar cable to cause problems further downstream.
HAPPY NEW YEAR EVERYONE!
