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.

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)
