= = = ... Anyone ever use Slinky Antenna's for Shortwave? Anyone ever use em for Amateur Radio? Whats your opinion? I'm getting ready to move into a townhouse here to downsize the home a bit since the kids are off at college.... Gonna have to go with Stealth type antenna's in the attic if I want to stay the hobby. Sonny SONNY, RECOMMEND - That you Set-Up the Two SLINKYs in the Attic using a Coax Cable Feed-in-Line and a Matching Transformer (Balun). CONFIGURE - The SLINKYs as a "Windom" Antenna {Off-Center Fed Dipole}. HOW-TO - First "Measure" the 'distance' that can be use for the Antenna in the Attic. This should be about Three Feet from the Peak of the Roof inside the Attic; away from the sides of the Roof; in Free Space (Open Air); and at least 3'-5' above the Attic Floor. - Mount your two End-Insulators at your two Far-Points. - At a Point that is ~38% to ~62% between these two Far-Points: Mount your Off-Center Insulator/Matching Transformer(Balun). - Stretch one SLINKY out between the two 38% Insulators. - Stretch the other SLINKY out between the two 62% Insulators. - Connect your Matching Transformer (Balun) (between) to the two SLINKYs. - Connect the Coax Cable Feed-in-Line to the Matching Transformer (Balun). - Connect the Coax Cable Feed-in-Line to the Radio/Receiver. NOTE: For a "RECEIVE ONLY" Windom Antenna designed for Shortwave Listening a TV type 300 Ohm to 75 Ohm Matching Transformer (Balun) and 75 Ohm Coax Cable can be used with success. TIP: RG-6 "DDS" Coax Cable with a Ground Wire 'attached' works well and provides for a 'separate' Ground Wire from your Shack to the Attic for your Antenna. CAUTION: "Make-Sure" that you establish a good earthen Ground Ground Rod and Heavy Duty Ground Wire for your Shack.
