Had me scratching my head also. I am guessing a rotating tower. ;) Keith WD5DXL How, pray tell, did you calculate 6 db f/b on a VERTICAL? ... Did you rotate it? Any WHY? Don N8DE Yup. I should have e
Agree with statement. But I think it does not provide much benefit unless you are trying to protect an antenna at or near the tip of the tower. If you ground each tower leg to a separate ground rod,
I need to obtain guy anchors for use in the Falkland Islands for a DXpedition this November during the CW WW CW contest. We will be using three types of poles to hold two tribanders (shortened) and a
If I were in your shoes I would contact ARRL immediately and get their advice. I would also get an attorney to represent me in all matters of communication with those who are complaining. Keith Well,

I just purchased a 1000DXA to replace the 800SDX that was fried by a recent lightning strike. It has been hooked up and tested on the ground. It will turn a F12 C-4XL. I have not seen the reviews, bu
I would not do this. The conduit will cause unnecessary wind loading on the tower. Just be sure you get quality cables and you should not experience any problems. I WOULD (and do, underground) run a
The parasitic element that reflects back toward the driven element is called the reflector. I think the name origin is obvious. If it were shorter than the driven element it would not exhibit this ch

Sounds like good, solid advice. It is good to have multiple grounds at the shack entry point. Of course, they should all be tied together with other ground rods at the tower, phone and power entry po
Interesting critique of a published article. Thanks. However, I did not post the link to provoke a response. I think it is a good, simple explanation for the original post: -- Why is the longer eleme
Called Polyphaser. They said the arrestors have multi-strike capability, but the insertion loss increases after each strike. I use only 4 of the 8 and can switch to the spares while waiting for repla
Try a long neck beer bottle standing on a 2X6 with shallow doorknob hole drilled to hold bottle. If this is too unstable or the weight breaks the bottle, try a glass building block covered with a fib
Concrete is a conductor. Unfortunately, if a large current flows through, as from a lightning strike, the moisture in the concrete will vaporize, usually causing the concrete to crack, and sometimes
LOL! What a hoot that would be. Of course, as you stated, you would have no ground loss, so it could get interesting seeing how much off-center power makes the trip to a DX station. Keith In the lim
I have a question. My QTH is a 16 acre parcel of an old 100 acre farm. When the holes were dug for the tower base and guy anchors, it was discovered there is 3 feet of topsoil, then several feet (at

Our club (NARS) built filters like this several years ago for Field Day. They are all-in-one with a switch to move from 10-15-20-40-80. I think the parts cost about $100 per unit. If you are interest
Having drain holes would not work in my installation because the water table is quite high. Instead of worrying about water in the conduit I use complete runs of quality coax (no splices or barrel co
