Nope. =Q#3= Are you using a AC 'Mains' Power or DC Battery Power with/for the Radio ? I operate everything, except my R75, SAT800, RX320, and Sony 6800W, off of alkaline batteries. I live in a community which enforces anti-antenna regulations by having the maintenance team report violations. My external antenna are different length reels of wire stealth-deployed for limited periods consisting of weekends, after 4pm daily and holidays. I would be grateful for any ideas you might have on what I can do to improve my antenna capabilities. Q1: What about the plans that are periodically posted on how to use telephone wiring as an antenna? Q2: Any suggestions on baluns? Sources of Info? Thanks, Mike PONG MWB : Improving Your Radio Shack One-Step-At-A-Time -was- VOA via Madagascar on 9680 @ 2105 UTC MWB, First -if-possible- Make yourself a Grounding Point 'connection' for your Radio Shack. In a multi-dwelling building complex a good earthen ground may not be possible so simply try for a fair RF Signal Ground. * Cold Water Pipes * Metal Window Frame * Center Screw on and Electrical Outlet's Cover Plate * Bottom-Center Round Hole on a Three Prong Electrical Outlet Take a 'portable' AM/FM Shortwave Radio with the Whip Antenna Collapsed and a short piece of Wire attached [12 Inch Wire Jumper with Alligator Clips on both ends] Turn the Radio 'On' and Turn to a non-station Noisy SW Radio Frequency : Test for RF Noise Grounding by touching the Alligator Clip to several Cold Water Pipes and/or Metal Window Frames. When the Radio goes quite/silent you have a fair RF Signal Ground. Attach the Alligator Chip and turn around the Bands to see if it is a good RF Signal Ground across the Bands. "IF" and only 'if' the none of the Cold Water Pipes and/or Metal Window Frames do not test-out to be RF Noise Grounds : Then try the Electrical Outlets for Grounds. -note- don't be surprised if some of the metal pipes and window actually increase the Noise Levels. FWIW -imho- Most modern Telephone Wiring Systems with the Internet and DSL etc streaming on them are Sources of Noise and very poor sources of good radio signals now a days. Do You {Can You} have a Dish-TV Satellite Dish ? -IF- "Yes" then buy a 'used' Dish at a Flea Market Mount the Dish as far-away and as far-up as possible. Run a Coax Cable or better two Coaxes to the Dish. Oops but they are not just simply Coax Cables : They are "Snake" Antennas made from Coax ![]() Start with 50, 75, 100 Feet* of Coax Cable : RE========[C]|-|=========S R = Radio E = External Antenna Connector '=' Coax as feed-in-line [C] = Clamp-On Ferrite Choke |-| = Gap One Inch Coax Shield Removed '=' Coax as Wire Antenna Element S = Short the Inner Conductor to Coax Shield * Most of the time making the Coax feed-in-line part of the Snake Antenna 'equal' to the Wire Antenna Element of the Coax Cable yields the best results in an End-Fed 'Linear' Dipole. -or- Try the 3/8 feed-in-line by 5/8 Antenna Element arrangement as an End-Fed 'Linear' Windom. Second Coax Cable Wire to a H-800 SkyMatch LF/MF/HF Active Antenna mounted in the Center of the Dish (---: hope this helps - iane ~ RHF |
