3KW SSB 1.5KW RTTY where it is RESONANT.
Otherwise be smart and reduce power out to avoid saturation of the core.
2 1/4" / 61 ferrite core wrapped using
14 AWG silver tinned copper with a Teflon jacket
sitting inside a 3" PVC round enclosure.
All stainless steel hardware used.
The dipole is constructed using top quality, Poly-STEALTH ™ 13. Breaking strength 370 lbs.
High Strength Aerial Wires are manufactured with high
strength, high conductivity Bare Copper-Clad Steel
(BCCS) and insulated with a high quality UV Resistant
Polyethylene to provide you with one of the strongest
and longest lasting antenna wires on the market today.
Advantages to Poly-STEALTH ™
High Strength Aerial Wires:
Ideal balance of strength and flexibility Low-Gloss finish
and small size makes wire disappear into the background
Superior abrasion resistance for running through trees
UV & Weather resistant for use on the seacoast or in
other harsh environments subjected to acid rain, high
wind, or high snow and ice loads.
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.
Can be used as a off center fed shortwave antenna to provide continuous coverage from 500 kHz to 60 MHz. SWL
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.
The antenna is very well built and works very good. I had it up for about a week and we had a very bad wind storm. Took down a lot of tree branches. I had one end at about 10 feet from the ground and a big branch fell on it. After the wind storm I took the branch off the wire and it was still ok. Great product. Thanks. Gene N1GCB 73s
I've had this antenna for several weeks now and along with a MAT Tuner mAT-y200 for my Yaesu 991A and I can tune across all HF bands. I'm very impressed with the build quality. I have it set up in an inverted V approx. 35-40 Feet above the ground.
The antenna has only been up a week but I'm impressed with how it is performing so far. With the exception of 30m all of the other bands have low SWR's and getting good signal reports.
The antenna is well constructed. It is tunable to a flat SWR on the 80-10 meter bands. I would recommend it if you are looking for a simple mono-dipole installation.
This is my 2nd KI4L OCF antenna. The first one I sold to my friend Dave, KC4TIQ. We BOTH loves them! I will add a link to my Rumble channel on our set up. Pay attention to the video in which Dave has his antenna analyzer connected to the antenna! https://rumble.com/v15lmal-ocf-antenna-install.html
Antenna is doing a great job and I'm receiving very good reports. I find it is a good quality built antenna and have had no problems putting a kilowatt into it. I like it and hope it serves me for many years.
If you have a decent size yard with some trees or supports, this is a great antenna that will resonate well on all bands but 15 and 30. Get that balun as high up as you can get it, and go! This is my everyday “meat and potatoes” antenna that I use on my DX101MP and an Acom 700S. Built tough, it has survived several WV winters. Chris makes great antennas!
This is my second of the same model. It provides excellent service in both North Carolina and New Mexico. I am pleased to have the antenna.
Just worked the WWDX after installing this antenna about 50' up in clear air between 2 redwood trees. I run a KPA1500 amp with an internal tuner and there was not one band it would not tune to 1.3 or less. I contacted every continent but Antarctica pushing around 8-900 watts with an occasional boost to 1000 to get through some heavy pile-ups. I already ordered a second one for my remote location! Awesome unit. So many SAY they can do what this one actually does.
1st contact, 20M, JH7MQD Japan, no tuner, 400W @30ft followed by Europe and S. America. Outstanding!, thanks;
I can't say enough about how much I enjoy the 7 Band OCF antenna first one works so well I bought a 2nd thank you for such an AMAZING PRODUCT - NE5C Jerry Johnson
I wanted to work with FT8 and other digital modes which are on the lower end of the bands. The SWR was higher than I wanted, and Chris took the time to work with me to get the antenna tuned for the lower frequencies. Greatly appreciated! :-)
Purchased my 2nd, 8 band antenna, so I could put one up at my brothers place, for when I visit. I have it diagonally on my property, to fit on the lot. Nice having multi band access, and made some great DX contacts, with just 100W.. I wouldn’t have purchased 2nd one, if 1st didn’t work out well. If you can manage the length, I think you will be happy.
Able to get balun up about 50 ft, and ends about 20 ft. Able to make some great contacts. Good swr on 160, 80, 40, and 20. Don’t do much on the other 4 bands, but will check it out. Great receive and transmit. Contacts surprised I was getting through on 100 watts.
Works great! Thanks for the fast service.
I have no comments. I have opened the box the antennas came in and have done no more with them. If I remember to do so , I will write something after the antennas are installed and used on the air. I expect that to be before winter sets in.
