- I have been doing some modeling on Jim Breakall's shortened vertical for 160 meters. The antenna actually involves 4 45-foot verticals, spaced quite close together, with horizontal flattops making up

- is 50 ohms, the short inverted L, L rather than the You are correct Pete. The ground losses are identical to a single antenna. What you essentially have with multiple drops is an impedance matching

- I may be one of those Pete calls "those with trees conveniently situated", and I am indeed "tempted" by this idea for a short vertical for 160M...:-)... hardly any of my trees are more than 60 feet h

- Kintronic also has a link to a more theoretical IEEE article on this antenna: http://www.star-h.com/publications/ieee2002.pdf In the end, this is just a permutation of a short fat vertical with a lar

- Note that the article talks about the Kintronic being 1/5 the height of a monopole, but in the actual tests, it was about 1/3 the height of the monopole. Basically, it's just a top hat loaded cage ve
