Let's say I have a free-standing vertical HF antenna transmitting about
10wa, and I'd like to run wires to something at the tip. Say an
anemometer, or a temperature sensor. What would be the best way to run
the wire up the antenna? If the HF vertical is a pipe, is inside the
best bet? If it's shielded wire next to a solid antenna, will that
affect the radiation pattern of the antenna as a parasitic element? How
much energy at the tip of the antenna will couple into the wire? If the
wire is carrying low-speed digital data (eg for a 1-wire temperature
sensor), how much isolation would it need (choke, AC couple, opto-isolate,
etc) to avoid getting the HF into the digital signal?

Thanks for any insight!

Hello Ben,

If it were me I would find a way to attach it to my roof vents or
somewhere else for sure. I'm just real skittish about damaging or false
readings from my wxr station because of my rf. Gud luck to you.
