Re: [IRCA] ALA 100 and related thoughts
Thanks Chris;
Kevin also thought that the uniform shape of the Crate may indeed work
better than just a random spool of unused wire. The "method behind my
madness" was an article that I had read about 20 years ago where someone
had inserted coils of wires (of equal size) with uniform spacing in a
beverage system and the author stated that it worked as good as a full
length beverage. Kevin noted that the crate's coils should spiral away
from the longwire and not run // to it.

Dave,
The antenna you described will pull in strong signals guaranteed and
maybe
less noise since it will be near/on the ground. I've spooled out BOG
antennas and left probably 200 feet of wire on the attached spool still
coiled up and couldn't tell much difference. Then again, with a much
better
coil form like a Crate Loop it may improve reception. If you do decide
to
give it a go, you may want to compare it with another antenna such as a
100
foot longwire/random wire to see if it truly makes a difference.

>>Chris/Nick: I have emailed Kevin S about using the crate loop, sans
varicap, as a BOG "wire compressor" (for lack of better term). While my
original example would not fit in a 50'x60' backyard, I guess that it
could be scaled down. My original example used 50' feet of wire on the
ground, fed into one end of the crate loop, then another 50' out of the
backside of the crate, attached to another 50' section, hooked to
another crate loop, then another 50' section, which would be terminated.
You would wind up with a 400' "wire equivalent" BOG in the space of
150'. He stated that it might work and he said that he has a slinky
longwire in his attic that works on the same principle. I have also saw
a slinky EWE antenna that looks unique.
