I'll need to get into more details in the next few days but basically a 2 1/2 story house was allowed to be built on the property next door south of me blocking out my big dish reception totally. I have a 9' spun aluminum dish on a heavy frame with the actuator. I have had no C or KU reception for almost a year. I got a welding shop to make me a 23' pipe that is 6 inch thick wall pipe reduced at the top to 4" to accommodate the dish mount. I currently have a round concrete pad about 4' into the ground with 3 mounting bolts on the base. I'm having a lot of trouble finding a local contractor to put it up for me. A local businessman suggested I start calling around to the sign companies in our city as they have cranes, trucks with buckets & the manpower to do the job. The pole/post already cost me close to $1000. I want to be sure the concrete in the ground will support this heavy post plus the dish/frame. Any thoughts? Would I need to dig deeper & add more concrete? I want to be safe & only do it once the proper way like my original installation (30 years plus).

Perhaps add guy wires or guy angled poles on three or four side of the new taller pole down to new cement for the wires or out rigger arms. Look at how the old tall masts on early sailing ships were set up. If your new pole is still near the welding shop have them add 3 or 4 "ears" with a hole in the center of each one a few feet below the top so they will clear the dish as it moves across the arc. How does one align a dish 20 plus feet up in the air? Very carefully! I just noticed a 10 foot mesh dish at a school which must have been on a 25 foot high pole. (two story school building right next to the dish)

To get the dish on the pole ya could use a gin pole setup or some scaffolding.
Get a half dozen guys to help you... Have lots of beer on hand, and fire up the grill.
You could setup the scaffolding next to it for aligning.
Top of my pole is 14 ft in the air, and to get to I have to jump up on to the shed.

On one tricky garage rooftop, we used scaffolding setup in front of the dish to get at it for alignment.
It was a 12 foot dish mounted on a garage rooftop with a pitched roof, roof mount.
Couldn't really get to it without getting on the scaffolding.

I agree with Boblop.  That 9' spun is going to sway unless it is guyed near the top

Many years back I stood up my 60 foot tall wind mill tower in one piece with just two people and two trucks plus one steel cable pulling winch. So again perhaps rather than a whole new concrete base I would consider those steel cables or steel pipe or angle iron angled braces to both limit wind loads from the dish and improve and stabilize the bigger load you put on the old smaller original concrete base. Here my two dishes which have the large concrete "chunks"  (2 foot by 2 foot by 4 foot) above the grass around the dish poles were intended to be the lazy way to firm up skinny 3.5 inch pipe. It has worked well to take out any shake in windy weather. Last year I put one of my 11.7 foot glass dishes on one of them and so far it seems to be solid. I wish the next land owner well when they try and remove those poles.

Thank you for all of your knowledgable respones. I was wanting to respond but I got into a bike accident shortly after I wrote this & messed myself up putting the project on hold. My back & neck took the brunt of the blow so I suppose I'll have to supervise for the time being. When I get home I'll post some photos & get into more detail

This is the latest on my plans to move my dish to a new 23' pole. I found a local company willing to do the job.
He planned to dig an 18" diameter 10 foot hole & fill it with concrete to support the pole.
Then after the cement settles for 2 weeks they will raise the post, move the dish to the new post & let me use their boom truck to tune the dish. The shocking part is that the total will be $4000
The concrete work is over $2000 alone. The dish will be 6 feet east & a bit higher. Not worth it in my opinion.
So how about if I get an extension pipe made for the dish, lift the dish off, extend the cables & lower the dish on the new extended pipe & tighten it down with bolts? I've done it years ago with good results. I might need to rent a scissor jack or something like it to do the job myself.
Opinions?

@Kermit! Could you post couple of pictures oif your existing installation? $4000! Are they going to pour gold instead of concrete? [biggrin] Last year I prepared ~12-tonn platform and installed 4.6m solid dish on it without hiring any expensive cranes. And total was way less than your estimate.

My entire life using the big dish I did all of my own work (except for the welding) with the help of my Dad. It's almost dusk so I'll take pictures in the morning and post them. I wonder if the pad from my current install would handle the new post? The concrete pad is about 7 1/2 to 8' deep. These guys were going to dig 10 feet deep. I also have a support post next to it that's at least 6' deep. I made the bolt pattern for the pad identical so it would match perfectly. I need to act quickly as the weather is going to cool off dramatically in the next few weeks. I really appreciate your assistance. I wish someone that had an interest in the big dish hobby lived in the area but it appears I'm on my own.

In a moderate breeze, an 8' solid dish at the end of a 23' pipe will move in and out of the sightline to your chosen satellite independent of how much concrete you pour at the base. Do you have enough room on your property for guys? Two levels of guys? That will help some if you can do it. Thinking out of the box, Can you find a clear spot on your land for a new dish? Maybe think in terms of a smaller mesh dish, since digital is more forgiving of dish diameter than analog was at the time your solid dish was built. You could give up C band entirely and concentrate on Ku. Just for fun, you could try a 3' dish with a c/ku lnbf and see what you get. As they say at wakes in Indiana, "Sorry for your troubles."

That Andrews is a gem..Love it...

Kermit 23' with a 4 1/2" pole?...That is crazy!..As mentioned guy wires but I see this as an alignment nightmare...Ur only way to do this?...Maybe some type of platform or different location in the yard?

Think I mentioned before.
If I was in his situation, I would try and go on or through the roof of my house instead.
Same way ya see the big dishes on local bars and restaurants.

So true majortom..A dish that high I would want some type of permanent platform just to get it tuned..There is nothing easy about this setup...Might as well have a platform on the side of the house...Heck when the other half is barking it could be a good place to hang out for a game or a race if set up properly[biggrin]

There is so much that we don't know about your situation: How big is your lot? Can you send us a drawing showing your lot, an idea of tree cover; your house and your neighbors house so that we can see what you are dealing with? Which satellites is his house actually blocking?  Maybe most importantly; What is your mission statement? Ku and C bands? See the entire domestic arc? Atlantic satellites? Alaskan? I forgot, where do you live?
