[TowerTalk] Unique Short Radial Challenge - N5OT Question

[David Robbins K1TTT]

I can see how it could have.  The loop is now close to the radials that will
pickup currents essentially omni directionally and couple them directly to
the loop.  This would probably overwhelm the pattern the loop has making it
appear to have lost its directivity.
