Greg, thread locking adhesive, such as Loctite or Permabond types, is essential here. Otherwise I suffer the same bolt loosening problems as you have. 73, Joe K2XX ___________________________________
I have stayed out of this discussion because things mechanical are not my strong suit, and I have had my share of rotor problems lately. At any rate, several months ago I had a discussion with Craig,
I have done it with a forklift truck, the boom and crane from a brick delivery truck and the crane from a rigger's truck. (It probably can also be done with a conventional tow truck, but I've never t
I use 8-pin Jones plugs and sockets (Chassis mount) for my rotor cables. The cables are hard wired to the sockets on the outside of the shack interface panel. 73, Joe K2XX ___________________________
That is absolutely right about the top section hanging up when trying to lower the tower in a strong wind. The wind tilts it so that it will not fall freely until the wind lets up. If you had been cr
If anyone out there has some 40M quad spreaders in good condition that they're willing to part with, I'd be interested in buying one or more. I prefer Cubex, but any manufacturer will do. Please let
While I haven't dealt with Tashjian in about three years, the communication lapses and delays reported here are about the same as I experienced. It is my distinct impression that Tashjian Towers is a
Martin, I can comment on your plan to use relays to short out the inactive drivers. It adds unnecessary complications. I do agree that it is essential to short the inactive driver elements, but that
Bill, I had problems fitting the T2X inside my LM-470s. However, I was advised by Skip, AJ6Y, who routinely installs tower systems, to place 1-2" spacers under the rotor plate. The spacers are made f
That scenario is consistent with the failure that I experienced several years ago. We were visited by a sudden mini-tornado, and I'd guesstimate that the wind peaked at around 100 mph. Tower was supp
Does anyone know if Titanex has a US distributor? I wrote their German office asking for that information but received no reply. 73, Joe K2XX _______________________________________________ _________
Thanks for the info, Andi. I've copied the TT list on this reply because several others suspected that Titanex might be out of business. 73 es 55, Joe _______________________________________________
I'd install either a 110' or 135' doublet fed with balanced feedline. In the latter case, you could let the extra wire droop in equal lengths from each end, but the difference in performance with the
Actually, I was going to mention the EDZ when making my suggestion. Adding (drooping) three extra feet to each end to make 116' is 30M EDZ and a true half wave dipole on 75M. I have successfully used
The original Ham IIs had aluminum ring gears. You should replace it with a steel gear and an improved heavy duty brake. Both are available from C.A.T.S. I have been told by Craig of CATS that it'll t
If one had to install a ground mounted vertical as far as 2,000 feet from the shack and wanted to avoid the expense of using low loss coax, could a balanced feedline be used as an alternative? The id
Rick, Jerry, Dave, Jan, Jim L. and Jim B.; many thanks for your informative replies. Jan, I will dig up that copy of HR and check the article by N4UH. First of all, I acknowledge that 2,000 feet of l
Anyone have experience with this hardline? Its attenuation at 150 MHz is 1.2 dB vs about 0.9 db for LDF4-50a and 1.5 for LMR-400. There are no data available for frequencies below 150 MHz. 73, Joe K2
Steve, many thanks for your reply regarding the Commscope SFX-500. Yours was the only reply that I received, and I have to conclude that Commscope is a new player in the coax game and that there is n
So I have now learned from several respondents. 73 and TNX to all, Joe K2XX _______________________________________________ _______________________________________________ TowerTalk mailing list Towe
