I currently have the Cushcraft 40-2CD. 2 el Forty which has been up for almost 30 years except when a wind shear came through and bent every element. It went back up with extra aluminum inside and is
The reason that most of the HyGain element screw clamps will not tighten the element is that the stainless bolt and nut will seize under pressure, and you will *think* it is tight, but it is not. The
Rohn 45. The 25 has the bottom section concreted in. I plan on drilling and epoxying a pier pin for the Rohn 45. When I cut it off the 25, the holes in the legs will be exposed. What is the best met
I'd highly recommend the 1116dt from Balun Designs. (Optimized for 160M, 80M, and 40M.) http://www.balundesigns.com/model-1116d-1-31-mhz-5kw-optimized-for-low-frequ encies/ Does this balun put the dr

Background: For 160 meters, I shunt feed my tower. The tower totals 120? high with 20 ft. of Rohn 35 rotating above the 100 ft. level. I have philistrand guy lines. All feedlines are grounded at the
<<How are you determining resonance?? Do you mean minimum SWR? How are you measuring it? Are you using the same SWR indicator for low and high power levels? Or the rig when running barefoot and the a

It seems from observation that much of the noise is generated in the monitor power supply. Some monitors use an external supply where you can ditch the manufacturer's supply and put in an analog DC s
I'll also put in a word for Hy-Power. I have one of their 40/80 dipoles. They are well built and will handle legal limit just fine. Jim - KR9U _______________________________________________ ________

Pete, I suspect that your measurement technique is the problem and not the AA-55. I've been through this not too long ago with an old Telrex gamma-fed 5 ele 6 meter antenna. It seems that no matter w
In the 35+ years my tower has been up, the stainless-steel guy anchor angle (2" x 2") reaching down 15' to an aluminum scrap semi-truck wheel along with 27 ground, all made from scrap stainless steel
