Default How get RF through a sealed window?

Perhaps.

In an emergency situation though, you do what you need to do and try not to
let the regulations keep you from saving lives and/or property..while still
keeping the regs in mind.

When I use my portable mag loop for 20 and 40, from my hotel room, I try to
place it outside my room...but that hasn't always been possible. At my low
power I would have to guess the RF I'm bathing in should only be slightly
more harmful than the X rays leaking out of my cheap "Made in Turdistan" TV
set. I certainly wouldn't attempt using this setup with much more than a few
watts of power.

As for my attic dipoles, I have never tried to measure the exposure level in
my home. I'll check in to that..but again, at 5w or less it can't be too
dangerous.

You'd have better luck with HF than VHF or UHF making it through any

solid
object. I have used a homebrew mag loop in a hotel room on several
ocassions with some luck..on 20 and 40.


Even in an emergency situation, I just don't think it would be a good idea
to string some kind of an antenna above the heads of shelterees and then
start soaking them with RF, especially depending on the HF frequency in
use. In fact, I suspect the FCC's RF-exposure regulations would frown on
one doing so!
