I have actually used a 1000' wire along a Pacific coast pier in southern California many years ago, and heard TP's but it was a bit of a fly by night (or at least by sunrise) operation, so I wasn't able to compare it with anything else, or do a serious study of its directivity.
As for the "pickup coil" idea, I think you would be better off to use a 9:1 transformer (make it an autotransformer if you can't get an external ground, presumably to the salt water) to connect to the QSR1. With the Degen, you'd need to experiment...maybe coil some wire around the radio, one end to the "Beverage", one end to the ground of the Degen, battery negative terminal or headphone jack sleeve. Pretty hit and miss I'd guess.

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---------------------------------------------------------------------- Message: 1 Date: Fri, 15 May 2015 05:59:41 +0000 From: Nick Hall-Patch <nhp@xxxxxxxx> To: Mailing list for the International Radio Club of America <irca@xxxxxxxxxxxxxxxx> Subject: Re: [IRCA] steel wire fence in Venice, CA (near Los Angeles) Message-ID: <20150515055942.CFFB25D18@xxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="us-ascii"; format=flowed 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.

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? https://www.google.com/maps/place/Venice,+Los+Angeles,+CA/@33.9651082,-118.4505142,17z/data=!4m2!3m1!1s0x80c2bac03052685d:0x8f1101b40d5c8d3c Aaron _______________________________________________ IRCA mailing list IRCA@xxxxxxxxxxxxxxxx http://montreal.kotalampi.com/mailman/listinfo/irca_______________________________________________ IRCA mailing list IRCA@xxxxxxxxxxxxxxxx http://montreal.kotalampi.com/mailman/listinfo/ircaOpinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officersFor more information: http://www.ircaonline.org To Post a message: irca@xxxxxxxxxxxxxxxx
