How long is this telescoping mast

I Looked at all the questions and one person says it not as long as 50 foot, I need this verified because I need 50 foot not shorter.
Asked by: Heatwave1972
Mine is the 50 footer but its about 45' overall.. you have to make up for the overlapping sections.

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.
Asked by: Dale
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!

Rated 4 out of 5 by from NOT a 50 foot antenna Despite Home Depot advertising this as a 50 foot antenna, it fully extends to only 39 feet 6 inches. It does seem quite sturdy, but just not the height I wanted and paid for.

Rated 2 out of 5 by from The screw clamps on this model are not near as heavy duty as other CM products that i have recieved in the past. I had to reinforce each unit to keep them from twistin in the wind. Also each one of the support wire holdings was bent - several of them not even usable.

Rated 1 out of 5 by from Damaged Product I ordered this product to raise my CB radio antenna above my roof top . The bottom end came to me damaged . Can you take something this long back to the store or take it to be shipped back . Impossible .I hope I will be able to bang it back out . Hope I do not make it worse . By the way it is not 50 foot as advertised . Disappointed . Home Depot you got to do better . RES in Anderson , S.C.

Rated 3 out of 5 by from Just as described I use this mast for a 30 ft tall vertical antenna on amateur radio. I have it extended all the way and guyed in two places in the middle of the back yard. Make sure it is straight and guy it if it stands alone. Working well !!
