[time-nuts] Austron 2100

[J. Forster]

The official 2100F antenna is a square shielded loop, roughly a 3' x 3'
meters, made of aluminum tubing roughly 3/4" OD. I think it's aluminum
conduit as the connections are made to the coil inside the conduit loop
via an electrician's box in the middle of one side. Opposite the conduit
box, there is an insulating segment, so the loop is not a shorted turn.

Before I got an official loop, I drove 4 nails in a roughly 4' x 4' square
into the 2x4 studs on the gable end of my attic and made a loop by winding
a few dozen turns of #16 wire on the nails. The ends of the coil were
connected to a piece of RG-58 and hence to the 2100F. Pretty crude, but it
has worked just fine in the Boston area for 20 years+. I never bothered to
put up the official loop. It could be shielded by wrapping with copper or
aluminum tape.

The LORAN signals I get are whopping and are easily visible on a 'scope
w/o any preamplifier.

If there are a lot of thunderstorms, the unit does occasionally loose lock
(1 or 2 times / year)

Best,
