Nick,
I should clarify that it is a steel cable fence. So there were three
cables running parallel to the ground, that do not touch each other and
appeared unbroken. Each steel cable consisted of several twisted smaller
wires (but still heavy gauge).
The cables ran through slots in fence posts - maybe 10 feet apart. The
supports looked non-conductive, but that would need to be tested.
At the time I had a portable Degen 1103 - which I haven't used with an
external antenna on MW (and I'm not sure how to overide the internal MW
antenna - you might have to induce the signal into it with a coil).
I also have a QS1R which I would just connect any antenna directly to
the antenna connector. But my main question is: "How effective is it to
use a pickup coil on a beverage antenna?" I'm guessing there'd be a
loss of sensitivity (though maybe not a huge issue if the antenna is
long enough - as the signal/noise ratio would still be very good).
Would there be any loss of directionality?
I didn't even consider that saltwater conductivity would hurt the
beverage directionality! How far should the beverage antenna be from
saltwater?
Thanks,
Aaron

Some unknowns here, Aaron...is it a single wire on supports? A "wire
fence" is a grid of wires in many people's minds, and that's mostly a
random chunk of metal as far as being a radio antenna. If it is a
single wire on supports, are the supports non-conductive?
Because the bike path is parallel to the salt water, your Beverage
effect may be quite compromised by the water's electrical
conductivity. I suspect you might just get extra signal strength
without much directional effect. As for hooking up to it, that
would depend on what sort of radio you're using. How would you hook
up a random wire to that radio? That might be a good starting point.
Good luck with this,
Nick

Could this work as a pre-made beverage?
Can you tap a beverage with a simple coil around it, or what is the
best approach?
