KeithYour statement below the excerpt from Jim, (below) is NOT true. It is not a matter of bleeding off the entire charge field, it is only a matter of changing the distribution of the charge. Changi
I think you will find that almost all grounding systems used by Army Ordnance to protect explosives storage bunkers use a heavy Copper Braid. I know that all I have seen were. It is not a flat braid;
Pardon me, but this is the biggest collection of garbage on this subject that I have seen. The braided copper conductors I have seen in explosives storage were about 1/2 inch in diameter, and were br
I thought I was nuts, looking through the August QST, then I went to the reading room (Dining room) and checked the SEPTEMBER Issue- there it was! Ward should be ashamed, he has an article in that sa
I always test the "copper" scrubbies with a magnet. I Had some rust on me, and found it to be just plated iron. (even though it was labelled copper) Bill-W4BSG Bill Aycock - W4BSG Woodville, Alabama
Jim- 6M is called "the Magic band" because almost anything can happen. A high gain antenna is nice, but I think you can miss a lot by having too much directivity. There is a lot of action that you ma
Roger- How DARE you point out the obvious solution? I read a couple of the posts on this thread- decided it was obvious and trivial- Then deleted MANY, and accidently looked at this one. Sheesh, inde
JeffWhen I commented on Rogers post, I did NOT mean the problem, or his answer were trivial- Far from it. I was referring to some of the answers that came earlier. Your problem is very real. Two aspe
I used GOOGLE and found links to the manual at both RC5A3 and RC5A-3 Bill-W4BSG We batter this Planet as if we had someplace else to go. _______________________________________________ ______________
I put in five of these for a Rohn 25, fold-over tower. (four guy locations and a side connection for lifting.) The use of 8" Chase was over kill, but I got them cheap at a bankruptcy sale. I am in Al
Gentlemen: I ave a Discone antenna similar to the MFJ-1868 (not the 1866) and I have lost (misplaced) the manual. I am hoping that someone out there has a copy. It is very small; just one or two page
This Whole post contains a major flaw that makes the real part irrelevant. The statement about the strength of 25g is worthless, because the shear strength is not define with respect to direction and
RichardI still consider that your post contains statements that are essentially meaningless, because they relate to loads in terms that do not directly relate without more explanation and definition.
AlI am in the same boat-- I can handle stresses and strains, and know the difference between "tensile strength" when the reference is cable or steel bar, but the cautions about where to hook up puzzl
I don't know how this could be done. It would be almost impossible to set the tensions correctly with only one adjustment per set. Am I missing something? Bill-W4BSG _________________________________
I have a real problem with this. I have asked for a description of the way a force is applied to the tower, and how the tower section is mounted, to show how this "strength" is defined. So far I have
Jerry- re the "copper" scrubbers- there are actually some copper ones available. When I look for the real thing, I take a small magnet with me to test with. I get some stares, but if they object, I m
JimDon't apologize- the first stuff to hit the list was fluff, and misled me, too. It was like a lot of 'crying wolf' stories I have seen. My initial reaction was the same as yours. I am glad that th
Kim (and any others)-- I make assemblies of copper that are normally used in the hand, and I have used lead-free (Tin-Silver Plumbing solder) for assembly. I use both Torch and Irons to make the join
Peter I have no dispute with your knowledge of weather, but you have not included all the phenomena; radiation heating (from the sun) is a significant contributor to the pumping action, and diurnal t
