Answer: 
It's 44' fully setup, it's actually 50', but those areas are recessed in the mast for stability.. If you want 50 ft. I would buy 5 - 10' century fence top posts, 18ga galvanized steel instead. about $65, then spend the big money on the down guy line setup. This is a nice tele mast, but heavy, expensive to ship, real fun to setup.. Sold my old one used the 10' options

How is this antenna mounted at the ground? Is a hole dug and concrete poured in or is there a mounting plate in the ground?

I have seen many examples of how this is done. I like the telescoping mast idea, but how does it go at the lower end? I'm not a rich man but I keep spending money on stuff only to find out it don't work!!! I'm wanting to get a HAM antenna up in the air.

First, be aware of your weather conditions in your area. Do not do it if you have constantly high winds year round!
You can either buy the steel plate online and concrete it in, or do this.
Basically, you can do this very easily with either a short galvanized pipe that goes into the bottom, or a steel rod. It does not have to be very deep, usually less than 2ft. Just to prevent horizontal movement. Dig about a 6 inch to 2ft hole round hole, and about 2ft deep. Bigger if you have soft dirt. One or two bags of quickrete to keep the pole from sinking in the ground, with the pipe sticking out about 4-6 inches is all you need.
The actual support system is in the guywire system, that MUST BE INSTALLED. This is NOT a free standing pole!
For the guy wires, put out your minimum of 3 support steel rods (with loops. I had a friend weld mine on) 3/4 inch diameter or larger, at least 3ft into the ground with a sledge hammer (or dig a hole at an angle and concrete them in). Put them at equal 120degree distances around the circle base of mast , at least 30deg to 60Deg vertical angle away from the pole, and drive them into the ground at least 30-40ft from the base of the pole.. Use good, rust resistant steel guy wires. Don't skip on quality here! Usually 3/16".
Don't forget to drive one or two 8ft copper grounding rod next to it (8ft apart if using 2), use a continuous 8 gauge copper wire with NO SPLICES and use a stainless steel mount to the Mast to prevent chemical reactions of dissimilar metals.. I am not an engineer, so please check with your local building codes. You assume all liabilities! Read Less

Answer: 
I installed several hundred of these in the late 60's and early 70's in Florida. After extending the lower section and leveling the mast, you can sink it 2 feet deep by twisting and putting weight on it. The wall bracket goes on at the eave of the house 9-10 feet up. I always drove an 8 foot ground rod next to the mast. I knew many installers who only used the mast as a ground with no problems.

Why can't I purchase this on line and have it shipped to a store. $55 shipping is too much. Not asking you to stock this item in stores, so space shouldn't be an issue
