50/60hz or dc shouldn't matter. the only way to get molten cables is by too much current, you can do that with either ac or dc, but you need some kind of high current source to do it. There are comme
lets see if I can describe this... my 40m 4-square verticals are rohn pipe towers supported between two 2x4's about 5' up. there are 2 bolts through the 2x4's and vertical that I insulate with fiberg
yes, the pull on the cable goes up quickly as the tower tilts... it can be way more than the weight of the tower, especially if not connected at the top of the tower and if it doesn't have enough hei

yes. all of my towers have at least part of a tower section, some have a whole tower section, above the top guy wires... then of course there is a mast above that. when tramming the top 40m yagi on m
now you are just trying to ruin the market... I was able to sell a couple of mine after I converted to greenheron. I still have a couple I couldn't sell and was thinking of trying again! I have a lar
yes, greenheron does ramp up/down when starting and stopping the rings which I like, especially on larger antennas. check to make sure that you have motor voltage coming out of the control box, you c
I used to have problems with them, but after carl gave me modifications to remove the spring loaded corner bearing with a fixed one they have been fine. the newere 1122 rings don't have a spring load

the controllers for the g800,1000,2700, and 2800 sdx and dxa are all interchangeable as far as I have seen with the exception of the plugs and one little detail... the 2700 and 2800 have an extra lim
