Re: [IRCA] steel wire fence in Venice, CA (near Los Angeles)

[Aaron Kreider <aaron@xxxxxxxxxxxxxxxxxx>]

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
