Introduction:
-------------

Below is what I have been using for quite a long time now
to stretch the reception range of my scanners on the
cordless phone/baby monitor frequency ranges. Using this
antenna, I have been able to receive about 10-15 more
cordless phones than with my discone or telescoping
antenna. I hope you will find this useful! Remember,
that stupid E.C.P.A. does not apply for these devices!


Required Materials:
-------------------

Coaxial cable - 50 Ohms - length variable depending on usage
Connector (to match your scanner)
Wire - Any kind, 30 feet or so


Instructions:
-------------

1. Attach connector to one end of the cable.
2. On the other end, strip off outside covering (about 1.5
inches). Twist braiding together.
3. Strip about .5 inches from center conductor.
4. Connect 10 feet of wire to the center conductor. Soldering
is the most preferred way to go here! If not, then tape
it up with electrical tape.
5. Connect 15-30 feet of wire to the braid. Solder this also.
6. Tape (or use some type of sealant) on the connection area
at the tip of the cable.
7. Finished, now hang it somewhere. Best results are obtained
by stretching it end to end as high as possible, but
in front of a window produces good results. Draping it
out the window is even better. Just try to keep the two
wires from running next to each other, this degrades
A.G.TENNA performance slightly.
8. Refer to below 'illustration' if you have any questions
or I can be reached on GEnie or The Hole in the Wall.

Please for info!
---------------

If you live in CA, especially the SF Bay Area, please call
me on The Hole in the Wall. I am looking for people to swap
frequencies with. I also need some good bbs's to call, like:


Spectrum Analysis Center - (714)/532-2300
A.N.A.R.C. - (913)/345-1978

Thanks to these bbs's for all the information that we have
shared. And join Radio Communications Monitoring Association,
I finally did! (PO Box 542, Silverado CA, 92676, $18.50)
