<p>Properly terminated good quality coax should not be susceptible,
but just in case, adding some ferrite chokes will be 'belt and
suspenders' protection.</p>

<font face="Verdana">Greetings,<br>
<br>
I'm contemplating the placement of the aptly named
'Franken-beam' and one of the likely locations would require a
coax run (AMR400) the length of my house. One of the easier
routes is through the unfinished attic space (approx 40ft).
There is an HVAC air-handler and an attic fan in the space but
it is otherwise unused.<br>
<br>
I'm wondering if I am inviting QRM from devices in my house,
power lines, etc. with such a run. I would elevate it by
running along the peak rather than along the floor, mostly to
avoid someone stepping on it or 'critters' noshing on it.<br>
