It works for me http://www.rogerhalstead.com/ham_files/ground.htm
Some say not to do this as the rod does not make good contact. Around
here we generally get enough rain that the rods will be in solid within
a day or two or it may take up to a couple weeks in the dry season.
Were this in a dry area I'd probably put some salts in the water filled
hole before dropping in the rod.
OTOH this probably would not work well in *some* sandy areas as the sand
would just keep refilling the hole. Here, what sand we have will hold
its shape.
