Re: [IRCA] Fence antenna

["Ira Elbert New, III" <ien3@xxxxxxxxxxx>]

So it's not a store bought balun? I guess maybe I could build one like that. 
I have a similar fence that I measured before, but I have no idea where I 
wrote it down. I want to put up an antenna like that, but I wanted to see if 
it was worth it first. More details later...

Hello Bert,
 
I have a 6' foot wooden fence along the sides of my house and back yard.  I 
use a balum to connect the antenna to the lead-in 50ohm cable.  The torrid 
core is shaped like a small donut.  The balum is 18 turns on one side and 6 
turns on the other side wound on the torrid core. One end of  the 18-turn 
side is connected to the antenna and the other end is grounded.  On 
the 6-turn winding, one end is connected to the coax inner wire, the other 
end connected to the shield.   The antenna wire is just speaker wire that I 
split down the middle.  I use egg type insulators at the end of the antenna 
and in the corners.  Also every 30' I use TV stand-off insulators to keep 
the wire from sagging.  Just screw them into the fence.   My coax cable is 
short, only about 12'.  I got tired of going out every night and setting up 
the EWE, and taking it down in the morning.  When conditions are goo! d, I 
don't mind.  But lately conditions have not been that good, so I hooked up 
the fence antenna to check frequencies and conditions.  I was very surprised 
that the fence antenna could hear TA's.  I also use a Palstar MW 550P and 
that helps improve the signal.
