With all respect for the company making this "Ropeantenna" but what is the added value of what they offer? That the radiating wire is threaded inside a rope... and what happens when that rope is very wet or wet and freezes up?
It offers nothing extra to a length of strong zincked isolated copper wire or stainless steel
small gauge cable, with HF isolators (easily found in a HAM shop) on both sides, and the top side indeed attached to a spare halyard
, and then run from the mast
to the side of the stern eg. the lower isolator attached to the pullpit. From there GTO-15 wire or the inner conduct wire of a RG-213 coax cable (outer isalation and mesh braid removed) leading to a through-deck isolated lead and from there with the shortest strecth as possible to the automatic antenna tuner.
Your total investment: not more then $60.00 with the through-deck isolator-connector the most expensive part...
With these advantages:
- you can easily and cheaply choose and tune the wire length according to your situation
- strong, simple and cheap
- certainly as effective as the commercial
- a thinner wire will have less windload than a full length rope-like stretch like this Ropeantenna.
I'm sure Bill Trayfors can fill in all the details on making your own, on the do's and don'ts and some practical design.
