I'd like to run 450ohm windowline inside 1/2" vertical PVC conduit for
about 8 feet to minimize the chance of kids messing with it and getting
hurt.

The line would come in vertically upwards through two 90=B0 pulls which
have a removable plate on the corner, the first of which would have a
box adapter bushing to keep the 1/2" dimension. The second adapter
would fit to the top of the PVC. This should keep water intrusion out.

Another 90=B0 pull junction would be at the bottom where the line would
enter a PVC junction box housing the lightning arrestor and remote
tuner. A 5/8"x8' ground rod would be the support for the box to which
the arrestor and tuner would be bonded.

What's the edge to edge dimension on 450ohm line?

Anyone done this and experienced big losses?

Should I expect big losses?

This would make for a nice clean installation and relatively stealthy.

tnx
