7-Band: 75/80, 40, 20, 17, 12, 10, & 6 meters. 135 feet (90+45) long.
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.
The wire used in the construction of this antenna is...
#14 AWG 7 STRAND Copper Hard Drawn with .030 High Density PE Black Jacket. Nominal OD .133”.
Making this an excellent choice for antenna wire! This is not the regular Home Depot #14 house wire, but a
rugged hard drawn stranded copper wire.
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.

I chose this antenna because it was one of the very few 80-6m dipoles I could buy that didn't require center support. I'm not even using a telegraph line, just the hard drawn copper antenna itself and there is very little sag. SWR is great, as reported in other reviews. Great antenna, I highly recommend it.

I replaced two antennas before I settled on the Ni4L OCT 80-6 HD and after hearing folk as far away as Italy just like they were in the room with me was enough to convince me that I had found the right antenna for me.

I bout this antenna to replace a new Alpha Delta DC-CC. I know it has coild but I will tell you what.. This antenna out performs the heck out of it.

Prior to this OCF 7 Band Antenna, I was using a multi band antenna in my attic. The difference is fantastic!
The following are the SWR readings direct feed without a tuner:
Feed Point is at 32 feet
I would recommend this antenna.

I was looking for an antenna to supplement my G5RV and that would get me on 80m. The SWR is way lower than my G5RV and the reception is better. I now use it as my main antenna.

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.
Feed point is 32' and the ends are at 10'.
Recommendation: BUY IT... it's very well made as well.

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.
