they work extremely well. and as they are virtually noiseles i hear
stations that can`t be heard on a regular wideband antenna
due to a better sn ratio, albeit, at reduced signal strength.....also,
unfortunately, with reduced transmission levels.....
( very good listening antennas ).

Hi Len (Lee?),

Are these commercial loops with substantial conductors (well beyond
what would be called wire)? If so, then pushing them into 80M is
going to be a trick unless the 3-30MHz model in fact works. If it
does not, it needs more capacitance, and that is going to be a loss
leader if you try to add any.

The only other limitation in the 20M band would be how high are they?

That`s why i need a larger, lower `Q` antenna ....which will also
fit in my garden space to t/x on.....

I like 20 meters a lot running Slowscan, Hampal and Digital Voice.

As far as 20M goes, your garden is long enough for a conventional
dipole - provided you have the support, and the direction favors your
need. If not, it seems unlikely you will gain anything over the
magloops. (Go for more height.)
