[TowerTalk] OCF Windom

[Mark Lunday]

Tom

My Elmer taught me that there is some confusion on these.

There are actually two types of antennas: the OCF antenna (sometimes called
the OCF dipole) and the Windom.

The OCF antenna is normally fed with coax, and should NOT have current long
the feedline (many antennas have current chokes to prevent the common mode
current that occurs with these types of antennas).

Some OT's will remember the single wire fed, Windom antenna that was popular
back in the day.  There were a lot of these on the air.

The Windom back then was a wire around 135 feet long, fed with a single
wire, around 1/3 of the way from the end.

What I am wondering is, is this actually a horizontal type antenna, fed with
single wire, or it is more of a 'T' vertical, with the feed wire actually
the radiator?

I think to actually be a vertical, it wound have to be fed against ground,
but I have seen recommendations for using a G5RV type antenna by tying the
center conductor and shield together and feeding it like a vertical.

Just curious.  73
