Being that the cost would be very little, I would simply take about 50 feet of
insulated hookup wire and run it back and forth around the underside of the
balcony ceiling; either taping or stapling it there temporarily. It's worth a
try and later on, one could add a balun or other upgrades. I lived for many
years in a 6-story apartment building in NYC and got good results with
everything from a length of wire hanging out of the window to a random-wire
strung between two laundry poles on the roof.

47 C.F.R. Section 1.4000 refers to video and fixed wireless signals; it
does not include broadcast and amateur radio reception or transmission.
You can install antennas for satellite video programming or
telephone/Internet services but not (for instance) for shortwave
reception.

The ruling also restricts installation to areas where you have exclusive
use, such as a balcony or patio. The roof is considered a common area and
is not part of the area protected for video/satellite/wireless antenna
installation.

For the situation DaveC describes, I'd recommend a couple options.
Stringing a discreet small-gauge random wire on the inside surface of the
balcony roof and/or support posts (if any) may work, particularly if a
balun or small tuner is available. I'm not sure what model Drake receiver
is being used but it's a cheap solution that's worth experimentation.

Another option may be an attic antenna (if there's an attic available) or
a random wire secured to the upper wall next to the ceiling. If you like
loops here's a link to one suggested configuration:

http://www.hard-core-dx.com/nordicdx.../housloop.html

I've lived in apartments for the past twenty-eight years and have managed
to work around most antenna restrictions by using extremely thin wire
(24-28 gauge magnet wire is fine, even thinner if you must) in locations
where folks don't expect to see it. I'm pushing the envelope a bit now; I
have fifty feet of magnet wire strung between two trees in the back
courtyard, but I have an alternate attic random wire in case the outdoor
one disappears (or is made to disappear). This signals I've gotten
through both this year have been surprisingly good.

Some interesting designs on this page:

http://www.g4fon.co.uk/

Although the design is for the ham bands, it would work for swl also
(same part of the spectrum).

I haven't built one of the loop antennas (yet), but plan to, as I am in
a similar situation, and will need an antenna for my 20m rig when I
finish it (under construction - about 30% done).

Another idea I have heard about, is using slinkys:

http://www.qsl.net/kd4cga/slinky.htm

The loop sounds like a better design, but if I can find a metal slinky
(all I've found are plastic in the toy stores), I might try that one
also.

Is there something conductive nearby? Like a downspout or gutter?
Attach a wire
to that. Just be sure to put the hole for a screw in a spot that won't
cause a leak.

Loops are not very effective above 5 MHz, and are inherently narrow band.
So called wide band loops (untuned) deliver low signal strength and need
amplification.

The best resort would be a very thin wire run where ever possible.

Dave,

Keep it simple... string a random length end-fed wire around the
perimeter of the balcony. Install it up, down, sideways, whatever fits
and is discreet. No need to try for a loop of any particular dimensions.
I use brown or black 24 gauge plastic insulated wire. Nylon ty-wraps are
a good way to anchor the wire if the balcony structure allows it. Don't
bother with plexiglas supports. It's OK if the wire touches the balcony.

Build or buy a small antenna tuner to put at the receiver end. Run a
"ground" wire (though real ground is hard to achieve above the first
floor) to a nearby window frame or outlet plate mounting screw.

This system works fine for me.

If you pick up too much local noise like TV buzz or computer power
supply hash, it might help to put a 1:1 ferrite toroid transformer
between the receiver and the tuner to break the common mode signal path.

Good luck, and post a message telling us what you end up doing.

Tom,

Search ebay in the toys & hobbies category. There are dozens of them, many
in good condition for a couple of dollars.

you could always just get a random wire tuner..... like the mfj 16030 or
something like that, forgot the model number.. where you take any length
of wire (I think it's 8 feet minimum) and turn the dials until you get the
strongest signal strength on the frequency you're listening too....
I have heard of people living in apartments getting them, running a piece of
wire to a raingutter (metal) and tuning it.... turning the entire
apartment's network
of raingutters into a large recieving antenna.
