Under your servicemeter base should be a heavy ground wire (typical home ground) that disappears into the ground, presumably to ground rods that are out of view under the ground. your ultimate requirement is to have one combined ground, all bonded together. The distance from your mast is too great (check if local codes apply), then you'll need a separate ground rod that is also bonded to the main ground. If the mast is close enough, you can run the mast and coax grounds directly to the main ground and dispense with the additional ground rod. This should be considered the minimum grounding exercise, you're always welcome to exceed the minimum.
