Try feeding it from one of bottom corners. ELNEC simulations performed
by a local ham (KE4ID) show that this configuration optimizes the
take-off angle for DX. Patterns from side-fed loops have a very low
angle of radiation while bottom/top fed loops have a very high angle of
radiation. I have used several corner fed loops with excellent results.
 Unfortunately, I don't have the real estate to do an A-B comparison
between corner and side fed loops.
