Default What to do with a 100' tower?

All might want to check at "alt.ham radio" under 100 foot tower. There is a
great picture of the tower and shack and fence etc. Sure looks like a pretty
nice "former ham shack" to me!!

Sorry bout the top post G

I'm thinking of buying a property that was once the sight for a
local dish satellite system. My first concern is liability,
although it seems very well built and there is no rust through the
galvanized tubing. It's 100' tall in 5 20' sections with three
cables at 3 places around the tower, total of 9 cables. A view
from the top would look like a triangle, each side about 3' and it
appears to be the same size from the top to the bottom.

I did just find a fairly close sign company with a 120' crane, but
today is sunday so I can't call. I don't know what the tower would
cost, maybe someone would take it for free if they take it down?
Maybe it's worth more?

If it gets expensive I think I could topple the thing one direction
where it is far from any buildings or trees. It actually looks
easy using the cables but that also sounds like a story for the
Darwin awards.

Any suggestions appreciated. I thought of renting out antenna
space but I figure it would already be done if anyone was
interested.

Looking for suggestions of things to ask or research that I may not
think of. I guess i could leave 20 or 40 feet there and put a TV
antenna on it!

Might as well leave the whole tower up if you're going to leave up
to 40 feet of it.

Liability. The house next door is less than 100' away.

If the tower is guyed properly and in good physical shape I wouldn't
worry about it crashing into the neighbor's house. I have a 65 foot
tall TV tower with a large ham radio antenna atop that I put up in 1980
that is not guyed (cabled) and it has withstood some storms that have
knocked down nearby trees. Funny though this tower is 10 foot sections
with a 9 foot top section. I can't recall seeing TV tower with 20 foot
sections. Even heavy duty tower for ham radio like what's available
from Rohn is in 10 foot sections.


20' sections are common for heavy duty commercial grade towers. These
towers are designed to last many decades and to carry significant wind
loads such a 10' diameter microwave dishes, panel reflectors, etc. This
tower probably has a face width of 24" or better and continuous fall
protection anchor point for climbing it. The light duty towers you are
familiar with are in a different class.


I've seen some fairly heavy-duty looking Rohn non-freestanding in 10 foot
sections. Obviously 20 footers would indicate commercial grade designed
for commercial heights. You wouldn't want 30 sections of tower for 300
feet. That's inherently poor in strength.
