W9IIX no longer makes mast steps. I used to have a listing of someone who makes aluminum mast steps, but I can't find it. I need about 4 steps for a 2' mast. Does not have to be aluminum. Any ideas o
the the space between the base plate and the top of the foundation block. I have purchased the proper non-shrink construction grout and am getting ready to do the job. But I'm concerned because I use
I do about the same but welded a 1/8", 6 "X 4" flat steel plate to the middle of the mast side of the angle stock. I mark the center of the angle/plate then drill holes about 4 inches vertical apart
That DC short to ground is one of the best things about them. IE, no static build up. 73 Roger (K8RI) like an OWA yagi. Just a 17" long bead balun, made from large type 43 beads, slid over RG-393 tef
All, The SWR on my 5 element mono band Yagi rises after I key down for a few minutes. The 2:1 SWR bandwidth behaves normally until the problem occurs. The SWR goes to normal after waiting a few minut
OK, is sealer or any kind of coating required/desirable for the top of a tower base ? I'm inclined to just leave it.,.so it can breathe/dry out if it rains. I'm thinking long term. But if sealer is u
Just re-measured the tower.... 37in on the bottom and 18 in top section. Looks to be an HDX-689. The base plate was not a standard T-Plate either...but a large full plate with 4 bolt holes per leg. E
I want to level my new US Tower HDX-589. I put a 4' carpenter's level on all three legs of the base section and have levelled them. This is all US Tower recommends. Is there anything more I can do? I
Hi Axel, This could be tricky. I think you need to run the coax to the antennas at the top of the tower inside the mid-level rotator ring, assuming there is room enough for them to freely slide witho
You only have to climb a tower once to know that you want as little as possible "complications" once you are "up there". Also, it is not the top of the tower that is exposed to stress, it's the botto
I wonder about the interaction. I don?t think a VHF contester would install his antennas for 6m,2m and 70cm with only 2" separation 73 Peter, DJ7WW on the same boom. It's the best compromise we could
The connector quality issue probably boils down to reliability and cost. However, in instances where the connectors are being used to accurately measure impedance and return-loss (e.g., VNA loads) th
Mice like the foam. It makes a great insulated "home". They will nest in fiberglass as well. Try stainless steel "Chore Girl" scrubbers to add structure to the foam. I've also heard of layering the f
Never even considered running anything greater than 500 watts through a PL259, to be honest with you. I know they are rated for higher power, but I've never considered them as being the right connect
Where every you weld on the outside the galvanizing will likely be burned off on the inside and likely at least half an inch farther than the actual weld. That's why the welding is done before they h
Dow corning DC4/5 is silicone GREASE ! It's NOT RTV glop. The dc4/5 is formulated for electrical connections. The dc4/5 goes on the threads, the center pin.....and the mating female, that the pin goe

John et al All this may be true to some extent but the majority of us don't have the option of stacked HF yagis at 90'? HI. I have never had an tower higher than 48 feet yet somehow have managed to w
