It's funny cause my dipole is made out of 300Ohm Twinlead. And at one time
before I got the balun I had the ends twisted together!. It was like a mini
loop really since I soldered the leads to an adapter. The problem in this
building is that someone would probably call the office if they saw the wire
hanging or try to pull it down themselves.
Now I was going to do this. The next highest floor is the 24th and that's
it. Not much higher to get to the roof. I was going to take magnetic wire
and crazy glue it along the very top of the roofs sides and run it down to
my window. But, I bought some and let it hang out my window while trying
it's reception properties.
The reception was terrible. Was this because the wire is so, so thin? I
wanted to use very thin wire so it couldn't be seen. What do you think?

Hi
Ok right now I'm using my JRC NRD-525 with a 35 Ft dipole and a 4:1
Current
balun coupled with a MFJ-959 pre-amp/tuner. I don't use the tuner that
often. As you know it amps the noise too along with the signal so I use
only
it when absolutely neccessary. I'm on the 23rd floor of a building so I
get
good signals.

LUCKY,
Forget the Dipole ETC.
Since your are up 23 Floors (10-12Ft X 23 = 230-276 Feet)
Vertical "Drop" Antenna # 1.
- Buy 100-200 Feet of TV 300 Ohm Twin Lead.
- Take the Far-End and 'bare' the Wires, then Twist the ends together.
- Attach a 8 Ounce Fishing Weight to the Far-End.
- Take the Near-End and 'bare' the Wires, then insert/connect
them to the Antenna and Ground Terminals for your Receiver.
- Lower the TV Twin Lead out the Window for your antenna.
Vertical "Drop" Antenna # 2.
- Buy 100-200 Feet of TV 300 Ohm Twin Lead.
- Take the Far-End and 'bare' the Wires, then Twist the ends together.
- Attach a 8 Ounce Fishing Weight to the Far-End.
- Take the Near-End and 'bare' the Wires, then connect them to
the 300 Ohm-End of a TV 300 Ohm to 75 Ohm Matching Transformer.
- Connect the 75 Ohm-End to a 6-25 Foot piece of TV 75 Ohm Coax
Cable. {Enough Coax Cable to go from the Window to the Radio.)
- Buy a "F" to SO-239 Adapter (RadioShack Catalog # 278-258)
to 'connect' the TV Coax Cable to the So-239 Jack on the Radio.
- Lower the TV Twin Lead out the Window for your antenna.
NOTE: Make sure that the Fishing Weight is between Floors
and not hitting (breaking) anyones windows :-{
