What’s a City Windom?
A city windom is a unique end-fed antenna design featuring a long wire plus a resonant matching network comprising a balun, a length of RG-58 and a line isolator.
The City-Windom behaves much like a normal Windom but is better suited to suburbia and can be suspended from a window to a suitable anchor point.
How Should I Use It?
There are three recommended configurations of the City Windom.
Option 1:
Sloper
Option 2:
Horizontal
Option 3:
‘L’ Configuration
Note: depending on your installation, antenna height above ground, angle of installation et cetera, the antenna may need peeking to resonance. Extra wire is included at the end of antenna but folded back to enable you to extend or shorten the antenna as necessary.
Where is it Resonant?
By careful design of the balun, matching network and matching network of the antenna, your City Windom has the following SWR from 0 – 30MHz:
