Hi, folks - I have seen a good of info on Full Wave loops, and as I
have mentioned before, I intend to get one going here soon.

I live on a small lot, and a full wave for lower HF freqs can have a
pretty lengthy perimeter, several hundred feet - which I do not have
room without lots of wiggling and gerrymandering.

However, as I understand it, small loop antennas (like Wellbrooks,
homebrews for MW and so forth) have the loops folded on top of
themselves, allowing a lot of antenna in just a tiny fraction of the
area, with multiple small loops making up the length.

Could this be done for a horizontal full wave, maybe just a single
doubling of the loop, so that you could stick, say, 120 meters' worth
of wire on just a 60-meter perimeter? Is there any reason to believe
that this would not be a good compromise, or that any special matching
might need to be accomplished? Would the wires need to be a minimum
or constant space apart?

If there are any websites with this info, which so far I haven't been
able to find, I would appreciate some pointers toward them.

Many thanks,
Bruce Jensen

BJ,

When considering "Stacked" Two Turn (2X) SkyWave Loop Antennas:
[ Try this amount of 'Spacing' between the Loops. ]

160 Meter Band = Two Turns of 254.5 Feet with 62 Inch Spacing
- Only 63.6 Feet per Side with a 2X Total Length of 529 Feet.

80 Meter Band = Two Turns of 134 Feet with 31 Inch Spacing
- Only 33.5 Feet per Side with a 2X Total Length of 268 Feet.

40 Meter Band = Two Turns of 70 Feet with 17 Inch Spacing
- Only 17.5 Feet per Side with a 2X Total Length of 141 Feet.
