Carl Mosley designed the TA-33 as a greatly improved replacement for his vest pocket antennas. He sold thousands of the TA-33, TA-33JR, Tig Array (750 watt version), and later TA-36, Classic 33 and 3

There may be real truth to this. I was calling around about some tower several months ago and I was told to buy it directly from Rohn or Landa Associates. I called a number in Atlanta I was provided

I have a letter from Carl Mosley from the late 60's saying put good quality lugs on both the shield and the coax center and connect them directly to the antenna. Dave K4JRB

A wind storm yesterday damaged my KT34XA. The front director has been turned on the mast (the boom to element clamp is sideways) and one side is OK although about 10 degrees out of line same as the c

Thanks to all who replied. I looked all through the manual (I have one from 1981, 1986, and two update manuals). There is no mention of the type of aluminum. All I find is 1" by 72". At one end are w

I have used a rotor plate for a Tristao Tower for 33 years. The plate sits on the cross bars and has a plate on all three sides below the cross bar. I helped with a US Tower Installation and it seems

Wison made a 6 el tri-bander that is similiar to the TA-36 Mosley. Wilson is long out of that business but perhaps Jim Wilson N7JW is on towertalk and can help. You might look on BAMA to see if they

John Webb correctly pointed out that Wilson made two Mosley clones. The SY 33 was a TA-33 and the SY 36 was his version of the TA-36. These were made after Carl Mosley passed away and before K0VUW bo

They have posted the gain and front to back for the 4 el version on their web page. The 4 el version uses 2 parasitic elements for 6 meters. One other thing I did get from them at first glance (it wa

The article was quite good except for pulling the tower up by a rope. It looks like a US Tower and the easier way is to use the tower raising fixture. They sell one for the smaller towers and one for

Don't forget about the portable tubular crank ups sold by Force 12. They are more expensive than the AB-577 but much lighter and smaller.. A friend has the 42 foot version mounted on the rear of his

W8BLA had the Gap that covers 160 and 80. During the 1994 CQ 160 SSB we ran comparisons with my Uni-Hat 31 foot folded unipole. One station we worked was Leo W7LR who is a good distance from Atlanta.

I think you are talking about the bolts that hold the tower at the tilt over points. Mine were originally black steel but the bolts and base stay put when you move the tower. I have moved the tower t

The charts on the SteppIR web page show forward gain and front to back all across each band. a 32 foot boom is probably too long for optimum on 10 and maybe 15. So far don't see a parasitic element f

The article about the home brew big Bertha mast at W0SYK was in a 1972 to 75 issue of 73. In 1970's prices he spent nearly $1,500 for materials..then there was the welding. A serious proposition by a

Someone in W5 had one several years ago. He said that the extra XA should be a total boom length of 58 feet not 48. Why not stack 2 at say 48 and 96 feet? 73 Dave K4JRB Im looking to find info about

The system shown on the towerdepot web page seems to be a way to lift big beams to the top of the tower (shown on a AN 70 foot tower). You still need to be able to have someone on top to lift the bea

The two best remote amtenna switches I have seen are : 1. The Antenna Mart Antenna switch ...you can buy from WB4GNT at MGS, 2. The HOFI Remote SWitch that is rated to 500Mhz. HOFI has a web site but
