*********************************************************************** * Cordless Telephone Antenna -A.G.TENNA- August 3, 1989 * * Designed by: Adam Gott (On GENIE: A.GOTT) * *---------------------------------------------------------------------* * For latest UPDATE, call: The Hole in the Wall BBS * * (415)/524-1329 * *********************************************************************** 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.
