Water in coax

It's nice when a guy can just do his own thing and when he wants.
The free standing to tiltover
Sounds like a good plan, I'd guess you'd need a full bottom plate to keep the legs from bending. I actually made some legs with the thought of a tilt but I'm doubting if the legs might cave a bit being still separated.
I hear ya about the arthritis I'm 61 too. Wear and tear from years of weightlifting and work. Shoulder replaced a little over 1 year ago, yep these ole bodies just wear out.
I have a 45' free standing tower...... I knew I wasn't getting any younger or stronger, so I planned all that into the build-out when the tower went up.
We now have a setup where I pull the base pins and the wife connects the ac power to the winch installed on a fulcrum point for that purpose only.
She actually lowers and raises the tower while I standby and monitor the operation.
That's a tough looking setup.
So I guess that's a pulley about halfway down what looks to be a fairly heavy I-beam and the out to an electric winch motor.
What's the winch attached to? Is it on like a receiver hitch to pop on the back of a pickup and I don't know why I even have that thought.
The winch is hard mounted (4 bolt winch base) to the 6 1/2" I-beam.
It is a Warn, 120V AC, 4,000 lb. for straight pull .......
The I-beam is 5' deep into the concrete base.......
The concrete base is 6 1/2 feet deep.....
The tower legs are 6 feet long.......
Oh now I can clearly see, I didn't even see that nice winch up there. Yeah thanks for the clarification.

When we installed a connector outside. First connection at the antenna two wraps of 3M 3/4 inch tape then Andrews sealer one wrap formed by hand then cover that with more 3M 2 inch tape first wrap loose (not streched) second wrap tight third 3M 3/4 inch layer loose. the last loose wrap will NOT unravel as a streched wrap.
Same at the bottom at surge arrester then same at last jumper connection from Arrestor to antenna switch inside.
The only purpose of the first wrap of 3M tape is call curtesy wrap. which makes removing the sealer easy when sliced length of weather proofing.
Water/moisture will migrate into coax by heating by sun and cooling at night the sun heats the coax which causes pressure in the coax. the cooling at night sucks in moisture which flows down the coax. So every day cycle a few drops of water adds up over time until it gets forced out at the other end. Even during a sunny day the clouds roll in dumping a rain storm cooling the coax causing vacuum in the coax again a few drops collect.
Sorry about the Rambling along trying to explain but water proofing pays off.

LOL Check out the specs on a Trylon T-500. No worries about the legs bending. It is 18 inches wide at the top and 42 inches wide at the bottom with HEAVY 60 degree angle legs, not tubular. It will support 52 square feet at the top in a 70 mph wind. The cable attachment point will be about 25 feet up thus taking a big load off the entire system while raising or lowering it. I plan to make a base frame around the bottom using 4 inch angle. Hard to describe exactly but I have it all planned out. I just need to get it down first to modify things. I will likely use the truck to raise or lower it to start off with until I determine the actual pull force required, and then buy a winch. Currently looking at the possibility of a 12-14,000 pound winch to be safe.
Okay I've had time to look around on the internet and check out your Tower. That's one big nice tower. That's a big ole wind force too.
You've got me go get the tape measure out and figure out just which Rohn Tower I do have.
Apparently it's HDBX48 wind load 18. Silly Rohn site says maximum boom length 10 ft.
Lol . What a joke on my 5 element thoughts that is. Hmm
