Brings that whole "near field/far field" thing into importance, eh? When you say "not too distant" do you mean 100 meters away? 20 meters? 1km? The whole project came to a screeching Hmm.. maybe an e

Neither had I, but several other relay manufacturers say the same thing, as do the reliability folks in aerospace. I'd venture that the ULN part was designed to match what folks were doing with discr

This doesn't always work.. the timing of the foldback of power and the internal tuning algorithm can result in interesting chattering effects. The tuner tries to minimize the reflected power and chan

What sort of mounting base is possible? How much load can it take? What's your wind/ice/snow requirement? Any vertical and a SGC tuner at the base, if you can lay some radials on the roof or tie to s

As a Ham Radio Operator, I wrote the Tower Ordinance here in Scandia, MN. in 1998 ( then a Township, now a City). What they had then was a re-write of Washington County's ordinance. What a joke that

Good deal for K8JHR. The small Utah town I live in requires a permit for the tower foundation, everything else is unrestricted. Guess it helps to have a former ham in the building ordinance departmen

55 ft seems to be a common number all around the country. It's probably just like boilerplate zoning ordinances and boilerplate CC&Rs. Someone picked that number long ago and others just followed sui

Just curious as to why 55 ft was chosen.  Seems like 65ft (about 1 wavelength on 20m) which would allow a good low angle radiation pattern on 14Mhz, would be better for hams.  I wonder if they though

That's all fine. But don't forget mother nature's restrictions -- the interaction of weather, your tower, how you install it, what you put on it, and the laws of physics. 73, Jim Brown K9YC _________

How is the ordinance worded? Park Township's (near Holland, MI -- but it's not the municipality in which I live) ordinance refers, I am told, to the height of the "tower." Thus some hams have argued
