The best OCF antenna I have used Time Owned: 0 to 3 months.
UPDATE: 11/30/24 - I had to remake my mounting for this antenna as I was getting RFI into the house wiring due to one leg passing over our roof where some wiring for lights was located. It was coupling RF into the house wiring. Earlier this year, I relocated the 90' leg of the antenna to be in-line with the short side, exactly east-west oriented, and well away from the house. At about the 50' point, the long leg makes a 85-deg turn to the north. That point is 28' off the ground. The end of the long leg terminates at 21' off the ground. I also installed a 1:1 UNUN at the feed point, which eliminated all the common mode RF I was getting. The antenna performs MUCH better well away from the house and support masts. I am able to work most station I can hear on all bands with 100w, which makes me very pleased with this antenna.

[Original Review 4/10/23] This antenna was purchased to replace a 40-10 OCF that didn't allow me to use the 80-75m band. I had measured my lot to be sure I had room for it since the long leg is 90-ft and the short is 45-ft in length. It is mounted 30-ft above ground at the feed point and is not a straight 180-degree in-line but, about 150-degrees. Each end is about 10-ft off the ground.

My calculations for the 90-ft leg were off and the last 8-ft of length had to be folded back across the top of the fence where it is mounted. This leg also goes over the roof of the house and at one point is only 2-ft above the peak. The antenna is fed by RG-8X coax and the connector at the top is sealed with weatherproof 3M #88 tape. The construction of the antenna is very solid with crimped connections and UV resistant insulation.

I use an LDG AT-100Pro tuner with my 100w HF radio. This antenna will tune below 3:1 with my radio's internal tuner on most bands. I was pleasantly surprised when testing the antenna with the tuner in-line that I could tune all the bands, including WARC bands, at the low end and high end, and show almost zero reflected power on my SWR bridge. I also heard a notable increase in signal strength while receiving on all bands. Compared with my previous 40-10m OCF, this one does a much better job with band coverage and reception. The price is certainly good. This antenna is also available in a 1-KW version. I would strongly recommend this to anyone. The real test will be withstanding the western Nevada desert environment with its intense sunlight and temperature extremes from -6F to 114F and high winds with gusts up to 100-mph. I believe it will still be doing very well many years into the future.

Best OCFD Dipole antenna I have used Time Owned: 3 to 6 months.
I bought this antenna. When the OCFD dipole I had broke from a Strom.
I was reading the comments on ebay for this 80m OCF dipole.
In reading the reviews. And looking at building one my self. This was a no brainer.
I received the antenna in about 4 days. Pulled up on my tower. And have been having a ball since. Works on all bands just fine.
And will load on 160. But I have not transmitted there yet. If your looking for an all on one antenna. Give this one a try. Build quality and cost. Can not be beat.
