Com" website is gone and the Link/URL is no longer any good. Presently the INFO on the Portable Wire Antenna [PWA] can be found at "Reo Cities .Com" Portable Wire Antenna [PWA] -by- Tom Sevart [N2UHC]http://www.reocities.com/n2uhc/portablewire.html The full description of the Portable Wire Antenna [PWA] is there. However the Image/Drawing/Photo of the *Portable Wire Antenna [PWA] does not come-up for me. Besides Wire for the Antenna Wire Element : You will need a Plastic Tube to wrap some of the Wire around. *I found that one of the larger Pet Store chains " PetCo, PetsMart, PetClub, PetLand, etc... Has clear Plastic Tubing in the Fish/Aquarium section. 1st find something round like a pencil, pen that is as large around or slightly larger than the thickest part of your Radio's Whip Antenna to use as a Sizing Gauge to select your Plastic Tubing. 2nd go to the Store and select your Tubing. 3rd follow the instructions/directions/guidance at : Portable Wire Antenna [PWA] -by- Tom Sevart [N2UHC]http://www.reocities.com/n2uhc/portablewire.html -more- Tom Sevart [N2UHC] -Web-Pages-http://www.reocities.com/n2uhc/index..html -source- Reo Cities .Com *IF* You are just using a short/small 15~25 Foot Portable Wire Antenna [PWA] Indoors {In-the-Room} with a 'portable' AM/FM Shortwave Radio running on batteries : Then a 'Ground' should not be needed. However -if- You are using a longer/bigger 30~45 Foot Portable Wire Antenna [PWA] Outdoors {Out-Side} with a 'portable' AM/FM Shortwave Radio using an AC-to-DC Adapter : Then a 'Ground' Wire should be used with the PWA Antenna and Radio for Safety. hope this helps - iane ~ RHF *. *. Twin (2) Wire Portable Wire Antenna [PWA] -first- For "Indoors" Use : Take your standard roll of Hook-Up Wire from RadioShack 75-Ft. UL-Recognized Hook-Up Wire* (20 AWG) http://www.radioshack.com/product/in...ductId=2049740 * Insulated and Stranded Copper Wire From a Corner of a Room measure the Length of one wall and the Length of the adjacent wall. Add 15 Feet to these two Lengths = Total Length. Wall #1 = 10Ft + Wall #2 = 12Ft + 15 Ft = 37 Ft. Using a 12 Inch Plastic Tube that Slides-Over {fits-over} your Radio's Whip Antenna. Find the 'Center' {mid-point} of the Length of Wire. Use Black Electrical Tape to Tape this 'Center' to the Bottom-End of the Plastic Tube; and Laying the Wire Flat along the Tube Tape the Wire to the Top-End of the Tube. Starting at the Bottom-End with the piece of of the end of the Wire that is un-Taped : Wrap the Wire around the Tube for 30~45 Turns either colse together {tight} -or- about one Wire Diameter apart {spaced}. -our-choice- Tape the Wire when you reach the Top-end of the Tube. Now with both Wires at the Top-End of the of Tube : Twist the two wires together for 6~7 Feet; and Tie a Loop Knot in them. Take the remaining Lengths of the two Wires and Tie a Loop Knot in each. Use the Double-Wire Loop Knot to secure the Wires to the Corner where the Wall meets the Ceiling. Use the Loop Knots in the Wire Ends to secure the one-each of the Wires tightly to one-each of the Adjacent Corners where the Wall meets the Ceiling. Just slip the Tube over the partially-extended {12 Inches} Radio's Whip Antenna :Functions like a Dipole Antenna and No-Ground is required. ~ RHF |
