How low did you have your horizontal loop?  We always use a 2 wave or so one 
for field day, (80m), but mostly use it on 40m and up to 15m.  It is always 
only 20 feet high, as that is the limit of reach of our portable ladder.

We get great signal reports, and work all over the country from the Central 
Southwest.

I have seen an 80m loop work less well than a dipole when low to a roof 
containing a metal edging, which we put off to detuning and coupling issues. 
We feed our loops with parallel lines, either 300 ohm window or 450 ohm 
window line.
