FO&A,
This Week's 'new' Shortwave Listening (SWL) Antenna : Linear Twin (2) Element Horizontal Wire Antenna - End-Fed Windom Antenna http://groups.yahoo.com/group/Shortw.../message/14164 63 Feet Long - - - a la John Doty Laid-Out : South-East to North-West (Far End) from the Back of he Roof of the House to the Backyard TV 'type' 300 Ohm to 75 Ohm Matching Transformer -Note- These are the Larger 3/4" Round Barrel ones that are usually provided with TV and FM Antennas and can be bougth in Stores. They seem to work better as a Low Cost Shortwave Antenna Matching Transformer; than the smaller 1/2" Round Barreled ones that are much cheaper. RG6 Quad Coax Cable Feed-in-Line about 25 Feet Long ? WHY ? Two End-to-End "Linner" Horizontal Wires ? MT:==================-------------------------------o 24 Feet Twin Lead and 39 Feet Litz Wire .. * The 24 Feet of 300 Ohm Twin Lead is connected across the 300 Ohm Side of the Matching Transformer. * The 39 Feet of Litz Wire [ 50-Strands of # 41 AWG ] is connected to one side of the Twin Lead. - Note the other side of the Twin Lead is not connected at the Far-End it Floats in Parallel. * The Total Length is 63 Feet for the Longer * Note the Shorter Wire is 24 Feet and it's Far-End is not 'connected; and this "other' Side of the Twin Lead Floats in Parallel to the Longer Side. .. Sort of : Acts like One Wire -and- Acts like Three Wires : * 63 Feet ~ 1/4 WL for 75m Shortwave Band ~ 3.9 ~ 7.8 ~ 11.7 ~ 15.6 ~ 19.5 ~ 23.4 ~ 27.3 * 39 Feet ~ 1/4 WL for 49m Shortwave Band ~ 5.9 ~ 11.8 ~ 17.7 ~ 23.6 ~ 29.5 * 24 Feet ~ 1/4 WL for 31m Shortwave Band ~ 9,4 ~ 18.8 ~ 28.2 Currently Rigged "Flat" at about 17~18 Feet above ground level. Might call it an End-Fed Windom Antenna . . . . . .. ..
