About 20 years ago, after erecting a 150 foot tower (Rohn 45G equivalent), I was inspired to continue toward a multi-multi station. I began to look for and purchase other towers and antennas. So far,
Before you decide on the height, use HFTA to plot your station's location. Higher is not necessarily better. -John NI0K Keith Dutson wrote on 9/5/2019 8:51 AM: About 20 years ago, after erecting a 15
200 feet from the shack is not an issue or practical limit if you're willing to spend money on control lines and Heliax. My towers are further away than that and they work great. If you can position
A key issue is taking into account not only the distance from the tower, but the tower distance + height of the antenna on the tower + length needed for rotator cable loop + additional length from th
There are fibre optic or Wi-Fi rotator controller available already (Green Heron for example). For the tower location, it is worth to remember that once you have two towers, at the correct separation
Keith, Several years ago there was a series of detailed articles on this topic by Eric, K3NA ... in the NCJ, around 2003/2004-ish. Tom, N4KG's rule was run them North to South, so that you don't find
I have the issue that Bob describes. Some 400' from shack to tower top. LDF-4 and LMR900 runs from the shack to the tower's junction box. Since I have power at the tower base, wireless solutions for
If I had that kind of available tower height and the flexibility to place them that you do, I'd make the 2nd tower also 150 feet tall and position it such that a rope between it and the 1st tower poi

Keith, LDF5-50A is only .2 dB per 100' at 30MHz. LDF4-50A is about twice that. Which do you have? 73, Steve N6SJ About 20 years ago, after erecting a 150 foot tower (Rohn 45G equivalent), I was inspi

Thanks for the many informative responses. One question was the size of the Heliax. I should have said LDF4-50A. I do have about 170 feet of LDF5. The best idea I have gleaned is to place the second
If you are going to do a wire Yagi with inverted vee elements, be certain to carefully model it using EZNEC, 4NEC2, etc. The rules of thumb for Yagi design yield a very, very poor antenna. I spent ho
