My vertical is 127' of Rohn 25 on a base insulator, with 120 1/4L radials. At the 119' level I have an 80m. dipole attached at the top set of guy wires, with about 400 ft of Phillystran attached to e
There are very few hats that 100% stop all current beyond the hat, since it is really an impedance ratio problem and the hat is almost never near zero impedance and the area above the hat almost neve
"My plan is to erect a 40-foot vertical using 1 1/2 inch diameter aluminium masting then to use the top set of four guy-wires declined at 45 degrees with a skirt wire connecting the bottoms together.
George My setup is similar to what you plan. I have a 50 ft vertical with sloping top loading wires. I modeled the antenna in EZNEC to find the best combination of top loading inductor and sloping wi
Earl. I have a Rohn 25 foot tower with a 204BA which you sent me the model parameters and it matched right down to the foot on 1.828 Khz with the data you sent. When K6VVA wanted to operate this stat
Folks, agree And likely what the correspondent is describing that you refer to as "upside-down Christmas tree" is not actually a complete description, and unintentionally leaves out some critical det
