[Lowfer] PI now E-W

Thu, 31 Oct 2002 14:00:32 -0500

OK, naive question...

If we are ignoring the horizontal wires and using just the vertical wires
for phasing, could I (theoretically) raise the loop so the bottom horizontal
wire is just above the metal roof? not sure if my trees are tall enough to
support this arrangement (no pun intended) but I can give it a try this
weekend.

Little chance of any changes today. Off to drum up business.

PI is still in keydown.
