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
I told myself not to enter this endless discussion. However the above comment got my attention. I fully agree with the statement especially when it comes to engineering Car batteries. They are the m
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
I purchased and read your test results... and was impressed by the testing protocol and thoughtful approach to the pragmatic problems involved. Makes for fine reading and inspires one to analyze its
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
When I went to the city here in Menominee, Mi. to talk about towers and heights, I was given a straight forward answer. Since I am on the edge of the flight path of the local airport, the highest tha
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 _________

Richards, amazing......I'd "push"it one step further, " but you said 55 ft tower, I didn't see anything about mast restriction !!" HI, Steve K1PEK _______________________________________________ ____

Alan: One thing you can do that a lot of friends of mine have done. This would be to put up the tower you have planned with whatever antenna on top you have or are planning on buying. Use this a whil
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
Greetings TowerTalkians = Good news and bad news: The Good News... my city allows towers and antennas, and there are NO PERMITS and NO INSPECTIONS !! The Bad News is there is a limit of 55 feet. Fort
Well I got it up and it works great, a little better than the Butternut about 3 s units or so consistently. I took it back down temporarily since I need to get the 40 meter counterpoise together for
Yippee -- Let us know when you get it up and working... and what freq we can find you on. No better test than to make a QSO, eh? == K8JHR == wires from the tuning tubes. == __________________________
