[Milsurplus] BC-131 loop antenna?

[Hue Miller]

Anyone have measurements on the loop antenna for
the Army's BC-131 trans-receiver ?
I am thinking i could have one made by a carpenter,
and then wrap it in copper or aluminum foil. I am 
also thinking it would not have to be foldable, as the
original item was. I suppose i would need thickness
of the element, overall length of each leg, and length
of part that cinched into the antenna holder. I was
previously just thinking, build in a transmitter coil,
like the BC-176 has, and call it a day, but the big
loop is more eye-catching and interesting and probably
a lot more fun to use. Oh, and don't move your torso
while keying that important message - we shouldn't
force the other guy to retune his receiver while
copying.
Tnx, Hue Miller
