Jeff --
I really appreciate you doing this research for us. Two additional
ideas come to mind:
1. Those of us with FT-817s could configure its two RF ports to use
different bands and connect the rig directly to the beam's antenna
connectors, bypassing the duplexer. For this purpose, higher-qualit

as in the texts below, there is something else going on here.
That Diplexor can not be all that bad. two reasons.
How many db down is the front to side of that antenna?
and I can not imaging someone would sell a diplexor that has greater
than 20 db of losses.
because of the statement that how
ower meter will tell the condition
of the diplexer.

Hi Bruce and all,
No problem. Actually, I wouldn't call it research as much as curiosity.
Maybe the research will come later when developing something better. :) I
know the antenna "works" but can it be made to perform better? The antenna
itself is of great quality and workmanship, it's the
individually to give an accurate number for each.

h so much more room to LOS. So I guess maybe we should ask if it
is possible to extend the timer by 1 or 1.5 minutes, if the bird can spare
it.

Hi Charles and the group,
FB on the numbers. Interesting to say the least and thanks for taking the
time to look further into this topic.
Questions? I have a few after looking at these n
Could very well be.
