Hello, After 40+ years as a ham, I decided it's high time to have a tower and decent yagi. To that end, I've accumulated a Force 12 C-4XL and am working on getting a used US Towers TX-472. I'm lookin
Hi Jon/W4ABC, Thanks for the info about alternative crank-up tower drives. I have a feeling I'll be revisiting it shortly after erecting my soon-to-be new-to-me US Towers TX-472. vy 73, Bryan WA7PRC
Hi Dick, You'd also need to know the alloy and hardness, which I bet they're not revealing. The ball bearings are pn 50335-01. They're available from Hy-Gain or Rotor Doc for $0.10 each. It uses 98 o
The 100% threaded UHF Fem-Fem bulkhead fittings are UG-363/U. Amphenol makes them as pn 83-1F. Distributor stock check: http://www.stkcheck.com/evs/amphenol/amphenolheader.asp?mfg=AMPHENOL&stype=ex
Has anyone had any DIRECT experience with DX Engineering DXE400MAX cable? This appreas to be their version of Davis RF's Buryflex400. With installation of my tower, I'll soon be buying a 500' spool o
Mark, Roger, and Jim, Thanks for the interest and concern but, I am interested in feedback from actual users of the DXE cable. Anything else is unnecessary (but I still appreciate the comments). vy 7
I don't need/want any more discussion about feedline. I've made my decision. Any further discussion is moot. vy 73, Bryan WA7PRC _______________________________________________ ______________________
IME, the latter is bestest when dealing with cables that don't take twisting very well (semirigid cables and types with aluminum foil shields). There will be minimal flexing. The former imposes more
Ditto. When I made a deal to buy my TX-472 from John WO6R, I originally tried to use the sole shipping broker that UST uses. They initially gave me a bid of $1200 to ship it approximately 1K miles f
My experiences with UST have been variable. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lis
Hi Tony, I'm in the process of installing a US Tower TX-472... 72' of lightning rod. I plan on using 2/0 wire (or equivalent), per the drawings I purchased from my PE (Hank Lonberg, KR7X). If I don'
There. Now I don't have to say, "Just ask Hank." I easily solved my guy anchors dilemma. My tower is free-standing. ;) vy 73, Bryan WA7PRC [BIG snip] _______________________________________________ _
Hi Rob, In the trades, the tool is referred to as a "demolition hammer". They are offered in various weights... 45#, 60#, 90#. Years ago, I had a 6'x9' concrete slab I needed to replace. It was aroun
An otherwise demure friend of mine from my younger years was a closet pyro. He loved to blow things up! He later became a starving musician. He was good at all three (blowing things up, making music,
I previously busted up a concrete block (about 1/2 cu yd) also using a 60# demolition hammer. Doing so was no more difficult than breaking up the 8" thick slab. The slab wasn't a patio and wasn't hau
The G800/1000/2800 manual shows the lamp to be 12V/100mA, and running on a 12VDC regulated source that is not current-limited. As we know, a lamp's filament has a very low cold resistance, and inrush

And, when it's time to remove said bolts, the threadlocker can be released with heat. I use Loctite 242 high-strength threadlocker in HP automotive applications, and it releases with heat from a pro
That would be the model D550 (260W/200W). They also make an even gnarlier 300W/200W gun. I believe only Binford makes one with more power! vy 73, Bryan WA7PRC ________________________________________
Hi Mike, When I decided to put a tower up, my county building department required wet-stamped plans for MY location. The plans also had to be drawn by a Structural Professional Engineer, currently l
