Default Lowbrow antenna question

Sorry for yet still even another "how do I make an antenna that..."
question, but I have no room for an outside antenna. Somebody
suggested the following: take about 40 feet of 16-18 gauge wire, wrap
it in a loop near the ceiling of the room with the radio, then connect
the ends, attach the now single end to an exposed end of a coax cable,
and connect the other end to the antenna jack (I have an Eton E1XM, so
the "other end" is an F-type plug connected to a Radio Shack F-to-PAL
adapters).
However, I seem to recall reading that tying the two ends together
doesn't work very well, and what I should be doing is connecting one
end to the coax wire while the other end is connected to the coax's
shielding so it can be grounded.

Do either of these sound like they would work reasonably well, or is
there something fundamentally wrong with the idea, and I should be
trying something more along the lines of "get as much wire as you can
run along as many walls of your house as you can and connect one end
to (choose one: the antenna jack, the radio's whip antenna)?

Use the jack if it has one. I'd try an ''L'' along the two longest
adjacent walls (up by the ceiling) first, before worrying about loops
and such. Loops are great antennas but they need to be vari-tuned.

All dimmers and halogen torchierres must be off. TVs and computers
don't help either. An active antenna in the window or outside would
work pretty well.

Loop antennas don't need to be tuned but your right not to worry about
loop antennas because they sure don't worry about you.

All dimmers and halogen torchierres must be off. TVs and computers

With the common mode antenna you propose you bet.

An active antenna in the window or outside would work pretty well.


This is the sort of thing that happens when you don't worry about loop
antennas.

There are active loop antennas that are made to go in the window or
outside. They have tuners.

That's how most loops are set up. Whether this alternative idea of
tying the ends together would work better or worse, I don't know.
