Im sure you are aware that Im quite good at research on the internet,
and did a fair amount of that, before posting my question. But there
are often tricks that individuals have come up that might be
appropriate


LOL...Yeah Gunner, I know you google, etc...
Which leads me to believe that you posted this as a spark (some on
topic for a change), there are a half a dozen site with plans for
simple magnetic (Ferrit bar and magnitic wire, you know the crap they
call an antenna inside an el-cheapo transister radio) which is most
likely what you'll end upmaking in the long run with your requirements
for 'low profile' Hell Gunner, just whip up one of those damn magnetic
antenns, make sure you've got plenty of lead wire, and simply set the
damn thing in which ever window works best for the station you are
tuning to. You can't get no lower profile then that and expect to
actually pick up anything., Heck, with a say 24 inch piece of ferrit,
wrap it with around 30 feet or so of magnetic wire. You can even add a
tuning cap if you want to get fancy, but as a general coverage antenna
you don't need all that for just receiving, YMMV. You can mount this
type of antenna in the window(s) either flat or top side.

If you need to be lower profile then the above, might I suggest a coat
hanger.

Forgot a couple of things about ferrit rod antennas. Since you might
be using this antenna indoors (like inside of a window) simply connect
the "Antenna" wire to one end of the coated magnetic wire (remove
coating where required), the magnitic wire should be wound around the
ferrit rod leaving an inch or two or rod unwrapped and each end. You
can tape up this whole mess or stick it inside of a piece of PVC or
whatever (plastic) to make hanging the antenna easier. Because your in
a metal RV, if you ground the radio to the frame, you will increase
the shielding effect of the Rv's body, so I suggest using some plain
old speaker wire cut to the same lenth as the magnetic wire in your
antenna, and lay this wire out on the floor, behind ****, out of the
way, but stretched out. Use this for your antenna ground.
If you place the antenna "outside" then none of this **** matters and
ground away...Anyways, it's not coat hanger and tin foil, but it ought
to work just as well.
