Guys,
I'm beginning to think that leaves on the trees is adversly affecting
the directivity of my beverages.. or the phase of the moon or...?
All 7 of them don't seem to show the directivity on 160/80 that they
did last winter.
Two are two wire beverages (one of the pair unterminated, the other
terminated to ground) and three are single wire with resistive
terminations. All 7 seem to suffer from the same directivity loss.
I've checked all joints, switching paths and even measured the
terminating resistor values (at DC of course). The Z values as
measured on an Autek RF-1 on either side of the transformers agrees
well with last year.
The one thing I can't readily check is the ground side performance.
I'm wondering if it is just too early in the season to expect them to
perform or because they are run under a canopy of trees which still
have leaves.
Any ideas?
