If you tend to setup at the same spot and no one else messes about around there, maybe add a ground rod at the base of the antenna. Use 5/8" 8ft ground rod and some #6awg thhn wire. Make it flush it near flush so no one but you knows that it's there. Might help. As far as performance at 20ft vs 30-40ft, yes this might make some difference but I would think it would be mostly locally. With long haul dx I've seen guys with their antenna literally on the ground and talk 5000 miles. I'm not sure how well the GM plays with being abobe ground level of or AGL. I can't personally say whether being up at 400ft vs the 40ft where my qth is located above sea level has much to do with it. The antenna sees AGL, so I would go off that first. Not to say being an extra 400ft in elevation isn't good, but it isn't the main factor you need to worry about. JMO. If you can bury a piece of pipe down deep enough that you can just drop your mast pipe in that would save some time. Also setup some guy wire tie downs at places where you might or would use them. Then maybe try a 36ft push up mast. Drop it a few ft down into your mast pipe already in place and then guied it off with some good Dacron rope. Even 550 paracord works well. Maybe it's too much, I've never run a static mobile, but I would think that if I were to go to a certain spot a lot for static dx, and not many people are around. Pound or dig a pipe just larger than your mast pipe down to 4-6ft. 3ft works but I like a bit of depth. Then add a ground rod. Drill your mast pipe and then add the wire to the mast. Then just leave enough of the ground rod mount up to get the piece of wire down into the hole and tightened. If you are using the fence post setup I would def. ads some ground rods to the setup and tie them all together and take one run to where the mast mounts and leave it with a proper crimped on lug and some no-ox. Tape and un-tape as needed to attach ground lug to mast. Also, add a small piece of pipe about 2ft already attached to your GM. Then just slide it over your current pipe and be done. Add a self tapping screw or bolt. This should make the antenna setup easier to put together. Don't know if any of the things I've listed will help, but maybe they will give you some things to ponder on. Good luck and hope to speak with you soon. 73 and God Bless from 2OR222 Daytona Bch., FL. operator Sean.
