Just about anything will "work" as the AT130 is capable of tuning a wet noodle.
However, to work well, you need a good antenna and ground system.
A whip will work, of course, but a 23' whip on a 29' LOA
vessel is a bit of the tail wagging the dog. I wouldn't do it. Better would be a traditional insulated backstay or an 'alternate backstay' if you can fit one on your boat. Lots of posts on these antennas. Basically, it's a random length of insulated s/s lifeline hoisted with a spare halyard
(or a dedicated halyard) and tied off to one side of the pushpit. If your boom will clear this, and you don't have too much roach in the mainsail
, then it's a very good, low cost solution which will last thru a hurricane
. Mine has been thru 5 hurricanes over the past 20+ years.
. There are many solutions which will work. The "100 square feet of copper" and "tie everything together" impreachments which have dominated the SSB literature and instructions for over 20 years are just plain bunk. Any experienced ham knows there are lots of other solutions.
I have successfully used -- and often recommended -- a wide variety of RF grounds including, inter alia:
- the pushpit/lifeline/pulpit complex
- s/s rub rails (like on Island Packet
- the steering
- large stainless steel
- tuned 1/4-wave radials
- untuned radials
- wide copper strap to the nearest bronze thru-hull
- wide copper strap to embedded-in-the-hull RF ground systems
- "traditional" and unconventional grounding plates under the hull
and, of course,
- the KISS-SSB system.
All of these can work, and can work very well.
Of these, the KISS-SSB system is probably the easiest to implement and works very well. It costs $145 and while you can build a radial system for less cost in materials, if your time is worth anything IMHO you're further ahead buying
one already built. Unless, of course, your boat has some ready solutions -- like the s/s rub rail on Island Packet
Every boat is different. I'd suggest that whatever you decide upon, you try it out with cheap
materials first, before you build and install a "marinized" antenna and RF ground system.
