Chuck/Don, A DB-1015 does not have an 18 foot boom, and it has 3 elements only. It's a really tiny antenna. I don't know about the TH-4 but I had an old TH-3 and the hardware was not what we think of
I would think that as long as you put the D4 in the same location on the boom as the old driven element you remove, it would work the same as the original Mosley. Perhaps if you really wanted to find
Haven't seen anyone state the obvious yet - if the straight section is built to the same dimensions and out of the same materials as the tapered sections (I remember seeing them in the old catalog to
This is the same reason I used one once. It was far from "comfortable" but also far from unsafe. I would do it again. I am used to seeing fearless stage techs on these things in theatres where the f
Remember too that at whatever height you put a multiband yagi, it may (probably will) only be optimal for one of the bands it's built for. Mark, N5OT _______________________________________________ _
Gents, you're not understanding each other. Take a deep breath and step back and look again. Mark, N5OT _______________________________________________ ______________________________________________
I looked at this commercial installation: http://tinyurl.com/2v5sea And maybe I'm missing something, but I would describe it as a "Bazillion Point Ground" (BPG) and wonder if this is better or worse
Masts with steps are sometimes the right solution for the situation. Here are photos of three installations I put in back when I did this sort of thing, and frankly if you can get past "that odd feel
Gordon et al, I hate climbing anything, but realized as a teenager that if I was to have the big ham station I dreamed of, I was either going to have to hire out all the climbing or do it myself. I t
Another solution may be to contact K5GO for some of his custom new in-the-box galvanized ones and see if he has any more left. Mark, N5OT _______________________________________________ ____________
There was an excellent NCJ analysis of this question some years ago. Basically in order to get a "Team Vertical" degree of benefit, you have to be where you're worrying about how much salt water gets
Question: is the noise made by a HAM-series rotator excessive or unreasonable? It is not silent, but I don't think it's excessive or unreasonable. It's certainly not as loud as starting your car. Pe
I have to confess I did not consider if: 1. the rotator user was a "brake-clacker" 2. the tower was close to the neighbor's bedroom window 3. the "brake-clacker" clacked the brake late at night So I
Dave, I checked out www.monoprice.com and I notice they carry something called "Enhanced Loud Oxygen-Free Copper Speaker Cable." I wonder if they have any RF cables that work on the same principle? M
I believe there are "early" ones and "later" ones. The early ones broke a lot and the later ones don't break as much. I have quite a number of the late ones in a box from a couple KLMs I scrapped if
I got quite a number of inquiries about these KLM boom-to-element insulators. I'll take $20 each + shipping. Mark, N5OT _______________________________________________ ______________________________
I have to agree. As soon as I noticed the taught guy wires on either side of the tower in the video, the critical comments here became suspect. Raising a tower with a hinged base and two guy points
Bzzt. Look closely at the video (clip #2 between about 0:30 and 0:38) and you can see three loose guy wires at the 70-80 foot height "just hanging there with NO ONE hanging on to them." BUT at the 5
Wow. This supplier may as well be called "Copper Unlimited" What a great tip, Bob. THANKS! Mark, N5OT _______________________________________________ _______________________________________________
In which case you *could* nest the 80 and 40 array without worry, right? Do the radials for each array have to remain insulated from each other or would one big ground grid work for everything instea
