Also, i plan to erect around 37 feet of tower with a hygain penetrator on top. The base will be in cement and a house mount around 20 feet. Will i need to guy the remaining 17 feet?
That is not a Rohn tower..with the penetrtor you might want to guy it..
rohn has the classic "z bar" between the legs..
Im wondering what it is. It seems to be in good shape. I cant find any info on it. Can i climb it? Will it handle a 4 element beam down the road? Sorry for the nube questions but this is not within my area of expertise.
Climb it?.....Only one way to find out! If it were me, I'd make it a tilt-over so I wouldn't have to climb it...
That's the way I have mine...All I have to do is take out one bolt on the two front legs, and both bolt's off the back, then walk it down...(although I don't walk it down anymore, I have a winch I use to lower it)
If you make it a tilt over be sure you have a proper mechanism to take it down and back up. Nothing sadder than a good antenna smashed to the ground.
OR snapped in two...
Because of the wind loading of a beam in a rotational direction, it is recommended to use a tower with diagonal cross bracing. Attaching it to the house will help, but the wind is relentless and never sleeps. It might be ok. Only one way to know for sure.
I have never seen any tower with bracing like that.
I have, Sold thru Radio Shack and Kmart - if I'm not mistaken this is typical TV mast - like from Philips.
It's an older design, and that in itself raises issues of if its' safe to use - it's been painted...So no idea of condition of the (spot) welds that were used in this era.
It's a light duty - not meant for heavy windloading antennas...
Looks like American Tower.I have some of it & it looks pretty much like that.I am getting another 80 ft of it & 50ft of it has a 5 element M2 yagi & a dual band Diamond vertical on it now without any guying & it has been thru a couple of Hurricanes & a bad ice storm with high winds.I will be putting a 4 element Shakespeare MegaBeam on it with no guys also at 50ft.
Looks like OLD style Delphi...Light duty...made for TV antennas back in the 60-70's...
Think Andy is right...Radio Shack/Allied Radio and Mom and Pop TV shops...
By age and the looks of those spot welds...Ground plane be about it...
If it has rust on the inside of the legs and it has pits in the steel...I would never use it for anything else. Just looking at pics. I would not climb it or use it in the Midwest storm region unless it was guyed MHO
All the Best
NOTE: looking at the picture...blown up...notice the splatter marks on some of the braces...and some curling of the braces near the legs...someone has tried welding the braces back on!!! Scary!
DON'T USE IT AND FOR GOD'S SAKE DO NOT CLIMB IT!! Look closely at the section on the left. The legs are SPLIT from freezing! My guess is it was laying down and filled with water which froze and split the legs.
True that CK!
