[Elecraft] Good Low Horizontal Loops

I can vouch that a 20 foot high large loop, even on 80m, (660 foot
around model we build for Field Day), works out pretty well.  We logged
Maine on SSB from Central Tx on it, so that is better than cloud warmer
range.  Also, most of eastern seaboard, midwest ,etc.. 72, Stuart K5KVH

I've worked across the country with a low dipole too. The expected "best
signal" distances for any antenna vary a great deal depending upon
conditions. 

Or are you saying that there is something "special" about a low
horizontal loop that is missed by antenna theory and analysis?  

These sources say that such a loop has a major lobe straight up, thanks
to the gigantic reflector right below it (the earth) with radiation at
lower angles dropping way down to zero at the horizon - very similar to
a low dipole or any horizontally-polarized radiator only a small
fraction of a wavelength above the earth.
