Truman,
Antenna is usually not grounded thru equipment since it is separated by transformer but often is grounded with thin wire to prevent static built-up (being isolated on shingle covered roof). It is not relevant if antenna makes your house 5 ft taller (compare to street lights or trees) but very important to prevent static charging from the wind that can make your house electrically look like skyscraper. Recommended grounding, found in every manual, is for that purpose (to prevent) and not for the actual accident since grounding rod has to be very thick and works only for small (branches) lightning. Main strike is 1 foot wide plasma that will melt most likely anything.
Lightning hits many houses with or without antenna and it could as well hit your house without grounded antenna (as it did hit my mother's house in Sarasota). Disconnecting antenna is probably a good practice in heavy lightning area.
