If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC in the US), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike.





I consider grounding the coax with a grounding block of primary importance for personal electrical safety. The antenna coax is connected to AC operated equipment which usually only has a 2-wire power cord instead of a 3-wire power cord. If the equipment becomes defective, the coax grounding will help protect you from electrical shock. I have had three close calls with electrical shock, so I'm a little more cautious than most.
