You want that ground more for RF purposes...A radio wave has a positive and negative (ground) component...eliminating the ground will not help. Before I divorced and moved, my antenna mast was a series of interconnecting masts, the ones Radio Shack sold before they croaked. I removed paint from each connecting end and blasted bit tip screws in. Connected a SOLID THICK ground wire to each screw before tightening and THOROUGHLY coated each mechanical connection with RTV. Installed my antennas (Made several of these) and also GROUNDED the mount to the antenna. Once the mast was installed against my garage, I GROUNDED the mast to a SOLID COPPER GROUND STAKE. Kept the GROUND moist when I had to relieve myself at 0200 or when the neighbors were not around.
Look in any military communications field manual, especially a Army Special Forces Communications book...If this worked for them, it worked damn well for me. Enjoyed some very unique VHF/UHF DX, such as monitoring Philadelphia PD here in Pittsburgh (GO FLYERS!) which is damn near impossible when band openings would occur....
Never, ever underestimate the quality of a good RF ground.
Trust me.
73 and Happy DX,
