Hi Cecil

Output power for my use will never exceed 100W, more typically 5W or
less. The RT-11 is only rated to 125W. But your caution on impedance is
just the sort of feedback I was looking for. I was considering running
the windowline all the way to the ground but was concerned about the
neighbors' kids getting their hands on it. My alternative was to run a
bit of conduit upwards to shelter the windowline until it was out of
reach, ~8ft. I was concerned however about how large such a PVC conduit
would need to be to avoid problems with the windowline. Would 2" be big
enough since its non-conducting?

tnx
