Hey guys. I am going to try to put up my 50' push up pole tomorrow. Is it alright to place it on a brick or concrete block or do I dig a hole in ground and place it over some rocks and fill up the hole? Yes, I have the ground rods when I go to put the antenna on it. Thanks.

Keith,
I would suggest you dig a hole in ground about 1 foot and place some rocks in hole to raise it above ground level for rain/condensation drainage. And / Or follow Marconi's and Starface' suggestion's posted below in this topic.
Note!
Corrected my brain fart from my earlier post above! 
==========
Bruce,
This is an easy question to answer.
Do a google Search for: Ham Antenna Push Up Poles.

Common sense should tell you that if you want the bottom to hold up and not rust out starting almost imediately, then put it on something to keep it away from the earth, else plan to replace it soon or cut some off and work it short.
If you put it on blocks, be sure to add something to give the base some support like a 4-8 foot ground rod right next to the base. This will help keep the pole secure at the base. |

Thanks Lon. I guess I should have asked how deep to dig the hole and how much gravel to put in as far as depth of rock. thanks.

Most Masts (push ups)when bought new came with a mounting plate the mast sat on, this kept the mast out of the ground so over time it didn't rust in the ground. (ALL METAL RUST IN THE GROUND)the plate had a hole in the middle of it for a 1 foot ground spike and the mast sat over it and that kept the bottom of the mast from moving and then a wall bracket to the top of the bottom section.
You can get a 1'x 1' 1/4" steal sheet and make your own, put a small hole in the center of it for a metel tent spike.
If you go with putting it in the ground it's self pull all the other sections up about a foot above ground then drill a hole in the bottom section 6" above the ground and put a bolt thru it. This will let all the other sections rest on the bolt when/if you ever have to lower the mast to work/change antenna.
Otherwise the part of the mast thats in the ground is going to rust and once you lower all the other sections down they will get stuck to the rust and you will never or have a very hard time getting the mast back up again.
I ran a Mast Business for 15 years.
Hope this helps.

Are you planning to fill the hole with concrete? I hope cause that would be funny to watch when it comes time to tension up the guy wires.
I installed my 2 pushup poles like this.
Pushup 1- I have a 4 inch wide galvanized pipe deep in the earth with concrete. The end pipe of my chain link fence against my house. It must be 5 feet deep! I just clamped the pushup to to the big pipe. It ALMOST needed no guy wires.
pushup 2- I pounded a large 8 foot long solid steel fence post into the tough Indiana ground half way with a sledge hammer. Yes it did hurt. Attached the pushup to the fence post with guy wires. Not the professional way to do this but no doubt nobody is going to ever be able to remove this fence post! IT will have to be cut off at ground level.
If I need to locate removal of my antennas and poles is simple. NO rusting of the pushups and they have been there since early 2005!
Whatever you decide you must support the bottom of the pushup somehow. At least until the concrete dries all the way.

Bruce, I know Radio Shack used to carry pushup poles, been at least 10 years since I bought one from there.
The 2 pushup poles I have now were bought at a Lowes hardware store back in 2004/2005. 30 footers and I think they had 50 footers.
Wow for some reason I'm craving orange sherbert now!
