Robert 11,
YES - A simple 'single turn' Loop Antenna in the Attic would be quiter then your current Random Wire in the Attic. * Plus add a 9:1 Matching Transformer to 'couple' the Loop Element to a Coax Cable FeedLine. * Use Coax Cable between the Antenna Element and the Radio/Receiver. * Ensure that the Coax Cable's 'outer' Shield is Grounded at the Radio/Receiver. * Use a good Ground Rod (earth ground) and Ground Wire to complete your "Antenna-Radio-Ground" System. THE BETTER IDEA: The more complex answer would be to study your "Attic Size & Shape" and the "Pitch" (Slope) of your Roof. Then Plan-Out an In-the-Attic Conical Loop Antenna (Folded SkyWire) for placement within the Attic. (Attached to the "Under Side" of the Roof.) = = = TOP VIEW : 40'L X 25'W _______________________________ | ____________________________ | | | ________________________ | | | | | ____________________ | | | | | | | *****************| | | | | | | | *****************| | | | | | | | x________________| | | | | | | |____________________| | | | | |________________________| | X |____________________________| = = = SIDE VIEW : 6'H ******x____________________ *****______________________\_ = 1 Ft Winding Spacing ***__________________________\_ = 2 Ft Winding Spacing x______________________________\ = 3 Ft Winding Spacing This is 'ruffly' a 400 Foot Folded Loop Antenna FWIW: A better Drawing of this is In-the-Attic "Conical Loop Antenna" (Folded SkyWire) is located in the PHOTOS Section of the SWL Antennas and AM & FM Antennas eGroup at YAHOO !

No transmitting. Presently have a single long wire (guess it's technically called a random length wire) running around the 4 sides of my attic, and then down to receiver. Works "fairly" well, but can't help feeling I might do better. Was wondering if there is anything "better" that would easily fit in an attic and still have pretty broad coverage (would settle for 0..5 - 20 MHz) that I might consider ? Thanks, Bob .. |
