The Next Step - The Low Noise Inverted "L" {Random Wire} Antenna - Question Shortwave Listening (SWL) Antenna Tuners - Do You Have An Opinion ?
MK,
Why Don't 'you' Try Answering the Questions Asked ? - - - vice - - - Going-Off and advoiding the facts and issues at hand ? MK - So 'you' are the type of Amateur Operator who uses one Antenna on All-Bands ? MK - Your 20-Meter Band 4-Element Yagi might be Great on the Amateur 20 Meter Band and be 'ok' on the 22 and 19 Meter Shortwave Bands - But honestly would 'you' use it on the 60-49-41-31 Meter Shortwave Bands ? ? ? For the Shortwave Listener an Inverted "L" Antenna that was 25 Feet High by 50 Feet Long would be a better General All-Band SWL Listening Antenna then your Yagi. Vertical-Up-Leg for 31-Meters = 1/4 WL @ 24.5 Feet Horizontal-Out-Arm for 60-Meters = 1/4 WL @ 47.7 Feet Total Length of the Wire Antenna Element 72.2 Feet = = = One Antenna : Built-It & Rig-It = Enjoy-It ) [ An 'average' size SWL Antenna that can "Fit" InTo the Urban Backyard. ] For the Shortwave Listener wanting something a little Bigger then an Inverted "L" Antenna that was 32 Feet High by 71 Feet Long would be a little better General All-Band SWL Listening Antenna - If they had the Space and the Ability-to-Rig the Antenna Wire that High . Vertical-Up-Leg for 41-Meters = 1/4 WL @ 31.8 Feet Horizontal-Out-Arm for 90-Meters = 1/4 WL @ 70.9 Feet Total Length of the Wire Antenna Element 102.7 Feet = = = One Antenna : Built-It & Rig-It = Enjoy-It ) [ A 'larger' size SWL Antenna that can "Fit" InTo the Urban Backyard. ] Alas, many Shortwave Listeners can only have an Inverted "L" Antenna that is a little smaller and 15 Feet High by 30 Feet Long would be the best that they could do for a General All-Band SWL Listening Antenna - Since that have very limited space and can only Rig oh-so-high. Vertical-Up-Leg for 19-Meters = 1/4 WL @ 15.1 Feet Horizontal-Out-Arm for 41-Meters = 1/4 WL @ 31.8 Feet Total Length of the Wire Antenna Element 46.9 Feet = = = One Antenna : Built-It & Rig-It = Enjoy-It ) [ A 'small' size SWL Antenna that can "Fit" InTo the smaller Urban Backyard. ] Note - The Par EF-SWL Antenna lends itself to this 'small' Inverted "L" Antenna Rigging and it is only 45 Feet Long and includes the Wire Antenna Element and Matching Transformer - Just add Ground Rod plus Coax Cable and you are ready to Rig-It and Enjoy Listing to your Radios. http://www.universal-radio.com/catalog/sw_ant/2205.html * Par Electronics EF-SWL http://groups.google.com/group/rec.r...b0c1f933b5e495 http://groups.google.com/group/rec.r...85739bddf54cc3 http://groups.google.com/group/rec.r...2c697b586250c4 http://groups.google.com/group/rec.r...802953c2ef0642 http://groups.google.com/group/rec.r...68cb105b4a370b * ABOUT USING - The Par Electronics End-Fed Shortwave Listener {EF-SWL} Antenna http://groups.google.com/group/rec.r...f41e85486b0ed9 http://groups.google.com/group/rec.r...11c0ac4f084b87 http://groups.google.com/group/rec.r...d00e8131ee9876 http://groups.google.com/group/rec.r...a68a64cf6d8a00 http://groups.google.com/group/rec.r...157d690257b8ad * Consider Buying or Building a better Shortwave Listener's (SWL) Antenna. Lets Think : Out-of-the-Box {Ready-Made} Shortwave Listener (SWL) Antennas WHY - The simple Random Wire Antenna is better than the Dipole Antenna for the Shortwave Listener (SWL) http://groups.google.com/group/rec.r...2ff595de9fea91 http://groups.google.com/group/rec.r...1e9554b3d7d7ee http://groups.google.com/group/rec.r...905736ffa71e6e http://groups.google.com/group/rec.r...023dcbd76abc37 http://groups.google.com/group/rec.r...90a154db93a89a MK - Remember for the Shortwave Listener the SWL Antenna is just-a-means to being able to Listen to "Their" Radios and Enjoying the Listening Experience. mk - enjoy being a ham ) -and- i will continue to enjoy . . . just being a shortwave listener (swl) - iane ~ RHF |
