Brian,
The Mid-December Weather here in Twain Harte, {Sierra Nevada Foothills} California today was Semi-Sunny with Light Snow (~30mm) and -1C Temp Getting Ready To Hook-Up A Random Wire Antenna -and- Have A Question... http://groups.yahoo.com/group/Shortw.../message/11671 Far-End-Fed Inverted "L" Antenna -Reading List- http://groups-beta.google.com/group/...e30053633904d9 http://groups-beta.google.com/group/...d43c05075de087 http://groups-beta.google.com/group/...b3ddbed819958d http://groups-beta.google.com/group/...7711375bb4d0bb Generally the Far-End feed-point usually produces the best results : Provided that the Far-End is away from more sources-of-noise then the Near-End (House Side). - - - It is not a good idea to run/route your Wire Antenna Element towards the Utility Poles. One of the things with the Far-End feed-point is not to have the Wire Antenna Element come all the way back to the House. With either the Near-or-Far End feed-point have the Antenna Element away from the House and away from most of your 'close-in' sources-of-noise is the better way of Rigging you Wire Antenna Element. House to ------- Horizontal Wire Far-End --------- Antenna Element Feed-Point ----- Length 150 Feet = = = 120 Feet 120 Feet = = = 100 Feet 80 Feet = = = 64 Feet 75 Feet = = = 60 Feet 60 Feet = = = 48 Feet 50 Feet = = = 40 Feet Those last few Feet (20%) closest to the House may be the greatest source of noise-pick-up (80%) from your total Wire Antenna Element's length. Note - This is 'if' you have done everything else in eliminating sources-of-noise in your House and noise-migration-paths along your Antenna and Feed-in-Line System. at least that is how i see it from my 'far-end' - iane ~ RHF . .
