> All,
> 
> I connected an audio amplifier  and signal generator the my WA  East/West
> copper pipe loop (50ft X 50ft) via a 10 to 1 matching transformer. I
> resonated the loop with 6 paralleled .47uf polyester capacitors and was
> able to achieve a loop current of >10A at 9k (Q was ~ 50). 
> 
> The field results were very disappointing. The range to my car-top
> E-probe, up-converter, and Lowfer SVM, was less than 1/2 mile!  
> 
> Yesterday, I was able to shoot a fish line over about 280 feet of the 470
> feet of tall tress I own in the woods in back of the house (after loosing
> two arrows, two days previous). The remaining portions should be no
> problem.  I also pulled over a 1/8" nylon line and should be able to
> install a #12 wire today or tomorrow. Hope that this larger loop shows
> more promise. I also came up with the idea of crossing the horizontal legs
> at the midpoint (235ft location), thus putting the currents in the two
> vertical legs in-phase, instead of opposing each other. Has anyone heard
> of this configuration? 
> 
> Will keep you posted.
