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

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 :-{

Probably a bad way to go as that antenna will be going right past all those floors
full of interference.

If he has access to the roof he'd be much better off with a horizontal antenna up
there.

Good deal, you can have quite the setup living up that high. I also have a 4:1
balun, for whatever reason...I only used it once and it went into the closet. I
got it out last week.

To you and the more knowledgable in here. What exactly would a 4:1 balun be
used for? I figured to string up some wire or dipole and be able to run coax
into your shack. I'm sure there is a better reason. ;-)

A 4:1 balun is commonly used with a folded dipole, but has other uses as well.

Additionally, I check the 'discrepancy frequencies' on Simons list vs. the
other list
at sign on, and 5746 was not being used at 2200 yesterday.

Steve,
Not to sound like a jerk or anything, but I don't care if the NSA said it
wasn't being broadcast on that freq and at that time, I know what I heard and
that's all that matters to me. It doesn't matter to me if they don't use that
freq ever again actually, at least I know I've heard it now. I thought it was
some big time target or something with all the posts in here about it. Turned
on the radios and badda-bing....there it was.

I've followed enough schedule and logs from ones *in the knows* ....to know
that they aren't always *in the knows*.

you could just run a buttload of wire to it though couldn't you Steve and then
run your coax to the receiver?

I read up about them. I know when I was persuaded to get it, it was in the
thinking of some day txing on it.

Well, I hate to disagree, but they were not on 5746 on Saturday at 2200. And they
were not there at 2215 nor anytime in between as I was monitoring that frequency
on a separate receiver. They were however on 11545, 9251 and 6959. Now, if you
can point me to a logging that shows LP on 4 frequencies at once I might just be
inclined to 'believe' you.

I'm not sure what you heard on 5746, but it was certainly not LP. That is not to
say that you did not hear it on 9251.

As I said before, you did post the logging under a schedule that is known to have
discrepancies (5746 at 2200 on Saturday being just one of them), so perhaps it
was wishful thinking on your part.

They certainly may have been there on Friday as they do use that frequency (5746)
at 2200 (on Fridays).

Sorry, can't let you slide on this one!

One can run a 'buttload' of wire to most anything. However it will not necessarily
work well.

thinking of some day txing on it.

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?

pardon the intrude! first- Ace is one of the posters i
would ask an antenna Q of. he has helped myself, and many
others on this list. second- have you thought of a loop?
i am one of the fortunate people to aquire an Ed-loop,
("Torus-Tuner Loop") from Ed before he died. i'm hoping
someone else will pick up where he left off. i got the
L P on the Edloop with a sat800 just this last sat. i also
use the sony loop in the car when on the road. it's a
little odd to see the loop in the pass-window, but it works.
J.A. uses a wellbrook loop in his apt. he says it works great.
put out a few Q here, or google it and see what you find.
how bout it- RHF ? you hang in the antenna/yahoo gps, what
have you got to say??? ymmv- just my .02...

DRIFTER,

YES - Since "LUCKY" is 23 Floors Up-in-the-Sky with a Balcony,
he can take his MFJ-959 Pre-Selector and build a single turn
