The best OCF antenna I have used Time Owned: 0 to 3 months.
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.
