Quickly switch bands and eliminate a tuner as one more thing to adjust. Eliminate send/receive tuner loss.
Due to the fact that one wire leg of the antenna is shorter than the other, the OCF is more convenient to erect than a regular center fed dipole. Less coax is required.
Check the SWR always BEFORE using with any antenna tuner.
Poly-STEALTH ™ 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.
The strongest wire of the group is ideal for the longest of wire runs with or without additional support.
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 W2AU is the preferred Balun of Amateurs worldwide. W2AU’s operate at a low VSWR from 1.8 to 40 mHz, and handle powers up to 2 KW PEP (at SWRs of less than 3:1). W2AU Baluns are transformer designs with ferrite cores to provide 95% minimum coupling efficiency. Each has a built-in lightning arrestor, hang up hook, and 600 lbs of pull-apart strength in a weatherized, rugged package using only stainless steel hardware and quality materials. Two models are available. The 1:1 matches 50(75) ohms unbalanced coax to 50(75) balanced dipoles. The 4:1 matches 50(75) ohm unbalanced coax to 200(300) ohm folded dipoles.
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 go
Can be hung Flat or inverted V configuration. Remember stay away from power lines.

I've had this antenna up for several weeks but just getting around to writing a review. Shipping was fast and delivery was earlier than I expected. I was very impressed with the wire used for the dipole. It unrolled completely flat and had no "memory" of being coiled. Very easy to work with. I won't comment about performance since that depends on many environmental factors, but two things are worth mentioning: 1) the internal tuner of my TS-480SAT doesn't like the phone portion of 75M. I will try shortening the legs a bit to see if that helps. 2) One of the reviews here mentions outstanding performance on 30M. Note that this antenna is not advertised as covering the 30M band, and the SWR on 30M is beyond the range of my internal tuner.
OCF Dipole 7 Band
Great antenna, high quality construction and materials.
Well built antenna
Well built, only got it up 20 ft on first install but works as advertised on all bands. Will try to get it higher which should lower the swr. I like the cut of the antenna for the phone portion of the band.
The antenna arrived in 3 days from my order. It was well packed and very well constructed. I was only able to install it at 27 feet high and as a flattop antenna. The antenna covers the upper frequencies of most bands so if you are a CW operator, as I am, you will likely need a good tuner. I wish there were an opportunity to specify the Phone or CW end of the band when the antenna was ordered.
Havn't installed yet but blown away with construction quality
As a professional electronics systems owner/installer after 32 years I know construction quality when I see it...Well done considering cost.
JT-65 30m QSO to Japan on 2 watts from Los Angeles ...
1) Hoisted the 7-band OCF dipole up about 30 to 35 ft high between the front yard tree and the backyard tree. 2) About half of the dipole runs over the single story roof by about 12-15 ft. 3) Fed with 125 ft of RG-213 coax (from MPD) into IC-7000. 4) JT-65 QSO on 30m with 1 watt into Japan (JA5XI) who received my signal at -25 and was also QRP at 5 watts on April 1, 2015. 5) Have used WSPR from Los Angeles at 1 watt on 30m with report from Australia at SNR -26. 6) Had checked into a few mid-west SSB QSO parties on 20m over the April 4, 2015 weekend using about 75 watts from Los Angeles with RS at 59. 7) Have recently used 10m (JA2ATE) and 12m (JH1MLV) JT-65 to QSO with Japan, and 17m (VA7HZ) JT-65 to QSO with Canada from Los Angeles. Also recent PSK-31 20m QSO into Cambodia (XU7TZG) on 25 watts from Los Anglees. So far a great antenna for digital modes and SSB. Will be trying lower bands 80m and 40m later.
Outstanding performance! The antenna construction is robust, recently taking 50mph gusts from a storm with ease, and the on-air perforance has been nothing short of spectacular.
Recommended without reservation for the performance and convience!
VEry satisfied with quality and and construction; hears well
Just strung this up at about 35 feet and luckily it just fit my yard space. Good quality well built and has good "ears" Working 100 watts I worked LU, CE, North Dakota and California. Generally if I hear them I can work them. Use it with a tuner to minimize SWR spikes but I'm happy I purchased it.
