Andina is correct.
We used an insulated wire between the tuner and the antenna wire, not coaxial. My apologies.
Andina is also correct about keeping the halyard taut, however once we ran the antenna up and tied off the halyard, we never observed it sagging.
As an aside, we were able to get excellect reception midAtlantic from Herb (Southside 2) even when other boats were experiencing difficulty with transmission/reception.
As a further aside, Herb got the best reception from a cat whose mast had been blown off and was transmitting using a boathook and bits of wire laid out on the deck. The cat's reception wasn't nearly as good though.

Once the RF signal leaves the tuner it should not be going through co-ax
cable - just well insulated plain wire - so I don't understand your
reference to running the coaxial to the halyard supported antenna and
connecting to it unless you are locating the tuner at the junction and the
coaxial cable is supplying signal from the transmitter to that. If you
can't locate the tuner at the antenna base and the route involves proximity
to other cables or personnel then coaxial cable will provide a safety shield
but it is not good practice and to avoid losses should be using coupling
transformers at each end of the coaxial cable to minimize losses.
Otherwise, such an antenna can be an improvement over a wire running
parallel to a grounded stay. It should be kept quite taut to minimize
movement so you don't go out of tune or have the tuner working overtime to
keep it tuned if it is automatic.
Regards,
Andina Marie Foster,

> As an alternative, consider running a halyard up the mast and securing it
to the pulpit or other appropriate place away from any metal shrouds or
metal backstays. Run your coaxial to the halyard, attach the coax to the
antenna wire and run the wire up the halyard tapeing it in place every
couple of feet or so.
