I had the 300watt version of the Buckmaster 80-6m OCF, inverted vee at 35'. Worked all continents, great signal reports, played very well on 40/20/17. Adequate on 80/12/10/6 for a multiband dipole. I even worked Poland and Russia on 80m SSB from the Tennessee Valley at this low height. Worked much better than a G5RV as a single multiband antenna.
It is built tough using heavy duty materials. I sold it for higher power rated OCF when I got an amp. I'd highly recommend as a multiband, one antenna solution and mount it as high as possible.
