My cheap Panasonic tv said signal strength was 73 percent in the attic and 84 percent on roof. I don't know if there was any actual science involved with the metering but it obviously shows some signal loss. I figure that when I add a splitter that attic signal would go down more I just wonder how low on the TV meter it can go before it loses the channel.

The signal strength scale is just a relative scale, and it's different on every TV. Your particular TV will tell you how low it can go and still be able to have good reception. You can add a splitter or two as an attenuator to make the signals weaker as a test, as in the megalithia.com link in my signature
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), 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.
