7-Band: 75/80, 40, 20, 17, 12, 10, & 6 meters. 135 feet (90+45) long.   

The OCF is hand crafted with the best materials. Each wire is swagged with 1/8" aluminum double ferrules-sleeves, at the balun and the ends.
The connections to the balun are soldered and crimped. Each connection is covered with adhesive lined heat shrink. 
The balun is the... W2AU 4:1

 Power Rated @ 1500 watts SSB. 

With a Heavy-Duty built-in center insulator and a large eyebolt to support the antenna without placing undue strain on the BALUN or terminals.

Manufactured by Unadilla, this is a 1.5 killowatt SSB, 4:1 for Windoms, Dipoles, Yagis and similar antennas that require 4 to 1 BALUN.


     Wire: #14 polyethylene jacketed FLEX-WEAVE™ - machine crimped for permanent connection: FLEX-WEAVE™ is a sophisticated hybrid aerial wire constructed of 168 strands of #36 wire in a #14 highly UV-resistant PVC jacket.  This innovation provides rope lay construction strength and high flexibility. It can be tied in knots to insulators and untied for repeated use. Flex-Weave is sometimes referred to as "wire rope" or "jewelers rope". It will not kink or rust out as will copper-clad wire. It is excellent for quads, dipoles, long wires, and rapid deployment (spooled-out) antennas. The PVC jacket has superior abrasion resistance for running through trees and is UV and weather resistant for use on the seacoast or in other harsh environments. It will stand up to acid rain, high wind loads, and high snow and ice loads.

Can be used as a off center fed shortwave antenna to provide continuous coverage from 500 kHz to 60 MHzSWL

No trimming - fully assembled, complete and ready to go with end insulators and crimped center and end connections.

Add your 50 Ohm coaxial feed line, suspension rope and away you go.

Can be hung Flat or inverted V configuration.     Remember stay away from power lines.

Wonderful replacement for a G5RV

4th Oct 2014

This antenna replaced my G5RV which was difficult to tune on several bands. My internal antenna tuner on my Jupiter was able to tune all covered band to 1.0.1 swr. Direct feed, without the tuner yielded excellent results as well. 80m 1.4.1 40 1.2.1 20 1.5.1 10 1.7.1 Feed point is 32' and the ends are at 10'. Recommendation: BUY IT... it's very well made as well.

Great Antenna for a Relatively Small Lot

GeorgeB on 30th May 2014

I just put up the OCF 7 bands 80-6 HF windom antenna. My lot is not that big so I have the feed point up about 40' on a small mast at one end of my roof peak. From there, the 45' leg stays up at 40' and parallels the roof peak to end in a tree. The 90' leg slopes down to the back of the yard to about 16' up and the whole antenna is somewhere between an L shape and a V shape. Feed line is 75' of LMR240. I tested with my RigExpert at the end of the feed line before I connected it to my gas tube lightening protector and this is what I got: 75/80M 2.30 SWR @ 3.900 MHz 40M 1.00 SWR @ 7.000 MHz 20M 1.21 SWR @ 14.300 MHz 17M 1.90 SWR @ 18.070 MHz 12M 1.00 SWR @ 24.940 MHz 10M 1.09 SWR @ 28.350 MHz I did not check 6M as I do not have a radio for that band. All-in-all, looks pretty good.
