George, Yes, you have correctly posted a thread to the reflector, though I don't see any other responses to your posting yet. Regarding the Ham M, are you sure the rotor was slipping and the antenna
Jeff, A good start is my website: www.erols.com/n3rr There's much more to learn, but take a look at my 205s and the gain curves I have on my website. Also, we'll need more info about where the lower
This is not recommended by all literature I've seen. The inductance of such a run of copper (or other conductor) will do nothing to prevent/stop/ground the lightning. Bill, N3RR
The horizontals are *very* important. As far as climbing steps, horizontals are nice to have, but they are *required* at the splice plates and at any location where there is an antenna side-mount or
TTs: As a result of Saturday's ARRL Web-article about my tower, many of you have requested the costs for my "Dream Tower". Well, I just uploaded a new page with *all* of the costs! Don't show this ne

It's a no-brainer: Metal - and steel at that. Aluminum will not do the following: With steel, you get the benefit of Faraday shield that you will not get with plastic or with aluminum. All cables (co
Yes, I wrote the sentence to fast. I left out the info about magnetic field for aluminum. Yes, metal will have the Faraday shield, but aluminum will not stop magnetic fields. Therefore, steel is the
Ed, Per the W3LPL cable attenuation tables on my website linked from: http://users.erols.com/n3rr/Cable/index.htm, at 1296 MHz the attenuation of 165 feet of LDF5-50A cable would be 2.5 dB. At 440 it
If you wish to re-use or sell the tower, that's not the way to do it. Likely, the tower will buckle without expert crane operation and experienced crew, especially since your post implies the crane l
Good questions, John! These are typical situations many hams encounter when designing and implementing a good lightning protection system. Let me address your questions in the order you posed them: b
I totally agree Glenn and was about to reply to Jon's response with a similar answer, except I saw your comments and yours are right on. On another point: I disagree with the theory of disconnecting
Jon, Generally, most large acreage ham stations do not tie everything together. That's why you hear that these stations frequently get lightning hits that wipe out equipment. Now to your other point:
My previous post answers a couple of the questions. To the question of where the lightning protection devices should be located, at, but not in, the house at the SPG is the best location. But, if tha
As I read some of the comments/questions about covering the lightning protection boxes, I'm wondering if consideration was taken into account for a Single Point Ground (SPG)?? If the lightning protec
Guy has it right. I couldn't have said it better. And my shack has all of what Guy says here. The SPG in the shack is a consolidation point (panel) for all of the equipment grounds in the shack and c
Let's take this one item at a time: Phone lines (TELCO) come into the house from the outside (either above or below ground). Most, if not all, codes require TELCOs to provide lightning protection on
