Folks - We are exceeding the single list posting topic limit for the subjects on
loops and attic antennas. Let's close the thread at this time in the interest of
keeping list noise level under control.

I used to have a mag loop too. It is ideal when it can be transported in
nearly original condition, when no tuner is available, and when tall
structures are unavailable. With a loop, one can be in the air in seconds.
However, the loop weighs a couple of pounds and it needs to be adjusted very
often.
Inside, loop's performance depends on the type of siding and roof
+obstructions. With vinyl siding and no outside obstructions, very good.
With metal siding, hard luck. An extra advantage of the loop is the ability
to null noises.
If one has a good tuner, a thin long wire weighs ounces and can be matched
automatically in no time. But setting time is higher and lots of space is
needed.
Once I had a business at a FL mountain (300ft!) during the time of a CQ 160
SSB contest. 2 x 150 ft gauge 30 wire from a window directly to nearest
trees. Good for 10 QSOs with K2/10. The wire + fishing line weighed a few
ounces.
No size fits it all.
