I just installed a new direct feedline on my 6m Yagi and
hooking it up to
Antenna 2.  When I tested it I was horrified when I saw
infinity SWR on my W1
power meter.  Then I realized the watt meter was not in the
6m feedline and the
rig was happily displaying a 1:1 SWR.

Hmm, that means there is output on ANT 1 when ANT 2 is
selected.  I switched the
ANT 1 connection to a dummy load and the W1 was showing .1
watt output from ANT1
with a 1.2:1 SWR.

Could it be that 6 meter RF is getting picked up by your HF
antenna, and fed down the HF feedline, messing with your SWR
meter?
