I like my Force12 C-4XL (40/20/15/19m yagi). There are 2 elements on each band. 10m uses two driven elements, IME to have low VSWR across the band. It is an interlaced design, using mutually-coupled

Back when Rohn was building Foldover Towers that was the factory recommended method for 25G towers up to 68 ft. The same guy scheme was also used with 45G Foldover towers. 73, Gerald K5GW In a messag

The half wave multiple is certainly needed for taking R +j measurements. For simple vswr measurements the vswr is not changed by the line length as long as line losses are low. This is assuming 50 oh

Get the very best balun you can afford. You do not want to have to change one out when the antenna is up on a tower. I had a BN-4000 attached to a tH-6 for about 12 years. Suddenly the antenna went d

Do you only find very weak signals? If not, try it. I found several parallel wires to widen the bandwidth. Wound myself a helix once for 10 meter and managed to make it cover the entire 10 meter. Han

Just thinking about some increased automation. The tower will be an MA-550 with a 2 el Steppir and 1 or 2 el 40M. A Yaesu G-800DXA should turn this. The Yaesu RS-232B is an amazing $600+ just to add

Another way to increase the bandwidth of a dipole is to run a wire next to it, slightly shorter than the dipole. (if I now remember it right). Due to coupling between the dipole and the wire you get

Here's a little Excel trick that will convert a decimal inches numeric value to the "closest eighth" or "closest sixteenth" as would be found on a typical tape measure. For example, a value of "26.68
