ABOUT - The "T" & Windom Antenna plus Twin Lead Folded Dipole Antenna
DH,
ABOUT - The "T" & Windom Antenna plus Twin Lead Folded Dipole Antenna http://groups.yahoo.com/group/Shortw...a/message/6309 The 'original' Windom Antenna was a Two Wire "T" Antenna. The "Up" Leg gets the Insulated Wire from the Radio up to the Flat Top of the "T". The Top of the "T" is un-equal : * The Shorter Side 38% of the Flat Top Wire Tip-to-Tip. * The Longer Side 62% of the Flat Top Wire Tip-to-Tip. = = = [ CLICK-ON-REPLY-TO-VIEW ! ] = = = Two Wire "T" Windom Antenna : *-------------------x------------------------------------* | | | | | | X = Solder Join Here Single Wire {Folded} "T" Windom Antenna : /-------------------------------------------------------* | \-------------------| | | | | | | Note - The Space between the Two Folded Wires can be 6"-12". 300 Ohm Twin Lead {Folded} "T" Windom Antenna : /-------------------------------------------------------\ | | \-------------------x x---------------------------------/ | | | | | | | | | | | | Note - Off-Center Fed Twin Lead Folded Dipole Antenna.

I recently put up a 25m wire antenna after getting permission from my apartment complex manager. Awesome. At least I finally have some metal out the window! Feeder requirements [and profile constraints] necessitated this antenna be of a "T" type, with a feeder in the middle of the wire. Anyone know much about this configuration? I am trying to figure impedance/freq response with the antenna. Thanks, Darren . .
