I've just put up a 160m vertical but I can not put radials in all directions. At best I can cover about 240 degrees with full size radials, in the other directions it is only possible to put down a f
Greg, The only thing I can say is that it's been a while since I heard of such stupidity as you tell in your story. Especially the part about working 'round the clock' totally exhausted on the tower.
I recently found MFJ to have outstanding service when I needed a bunch of spare parts for one of my TH7's. First class help in identifying what parts I needed (full rear driven EL + beta assy), then
grinding, it is the constant movement caused by the wind that does it. Even a small gap between the two tubes will make it possible for the wind to move things a little and after a few years the wea
Geeeee....... Make a search for jdbgmgr.exe on Google and you'll get the info you should have had BEFORE you sent this message.. /Peter SM2CEW Weather Stations", and lot's more. Call Toll Free, 1-800
I would not call the AR22 indication system a servo control system. It is a solenoid stepper system that is actuated by a switch in the rotor unit. Very simple. The good thing is that the readout is
Hi Barry. I have a similar but homebrew tower and I live at 65.4 N latitude so I see a fair amount of ice and snow here, and indeed high winds. I have put a set of guys at the top of the tower using
Gents, Anyone with experience of putting a 30 mtr beam close to (8 feet separation) a TH7DX or similar tribander, will there be interaction on any of the bands? 73/Peter SM2CEW www.qsl.net/sm2cew
I have my gut feeling about this. Sometimes these experiences are a reflection of how YOU behave... it takes two to tango.. I have good experience with MFJ, but then again, who am I, happy customers
My old 80 ft tower had this problem, cracks in all three legs from water freezing, splitting the legs. The cracks were about a foot up from the bottom of the tower. I welded a "dot" at the upper and
Making the cross pipe long will indeed reduce rotor instability but also degrade the beam quite a lot. The same will happen if the cable is made of conducting material, especially when the elements a
So what could happen when he rocks the top section he is sitting on himself ?? Will it jump 6 inches with him on top and come loose.. ??? Come on... /Peter SM2CEW www.qsl.net/sm2cew http://www.mscomp
I'm amazed at how some of you can say that $20 is considered to be high price for 16 pcs of specially made spare parts for an antenna. This is year 2002 and prices have gone up since the 1960's.. sho
But we still have to download everyone and his dogs story on how he protects his computer.. As someone said, an eye opener will be ok but not this endless blah blah about AV products and 'smart' setu
No they are NOT... They're focused on a problem that exists in "Da Land of Da Free and..." and for us who live in other countries the debate is not the least interesting! You guys have gotten yoursel
Fellow towertalkians, regarding Jims questions; Am I right in assuming that the F12 yagis are designed for 20, 15 and 10 mtrs and 17/12 mtrs only work because there is a load at the end of the coax a
Hi Tom. Yes, I understand that, but my point is that advertising the antenna as a 5 bander opens up the opportunity to do the same thing for virtually any antenna as anything at the end of a coax wil
Dan, I used an AR-rotor (think it is an AR22) for years, turning my 6 x 16el EME array..! The yagis had 30' booms. Of course, it drifted a bit in very strong winds but I never had a problem with it.
What power level are the traps in a TH6DXX/TH7DX capable of handling ? I understand the BN-86 balun restrictions, but I'm interested to hear what kind of power people have been abusing the traps with
