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.

Note - Center Fed Twin Lead Folded Dipole Antenna.

* 40 Foot 'Shorty' Multi-Band Twin Lead Dipole
Top Dipole Wire = 40 Feet = 25 Meter Shortwave Band
Bottom Dipole Wire = 31 Feet = 19 Meter Shortwave Band
Folded Dipole Wire = 49 Feet = 31 Meter Shortwave Band

* 49 Foot 'Average' Multi-Band Twin Lead Dipole
Top Dipole Wire = 49 Feet = 31 Meter Shortwave Band
Bottom Dipole Wire = 34 Feet = 22 Meter Shortwave Band
Folded Dipole Wire = 64 Feet = 41 Meter Shortwave Band

* 65 Foot 'Larger' Multi-Band Twin Lead Dipole
Top Dipole Wire = 65 Feet = 41 Meter Shortwave Band
Bottom Dipole Wire = 40 Feet = 25 Meter Shortwave Band
Folded Dipole Wire = 80 Feet = 49 Meter Shortwave Band

Hi all.

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
