could a lightning arrestor protect UHF/VHF/TV Antennas (RCA, Winegard, Channel Master, Omni-directional antenna, Semi-directional antenna, Off-air antenna) from a lightning strike? many of the antennas could be affected by lightning, tornado or other weather conditions.
I don't think anything would really help in case of a direct hit, other than unplugging the equipment. I would think that OTA antennas that are mounted on the house are also not as likely to get energized by the dissipation in the ground of a nearby hit, compared to a large dish that is often planted in the ground at a distance from the house (creating a voltage differential with the house ground).
In my opinion, the biggest threat to antennas is wind and maybe heavy sticky snow, but of course that's not a threat to the indoor equipment.
when i was a kid, we had antennas about 6 meters above the roof, for a total height of about 16 meters (about 50 ft). The mast was kinda grounded. Back when it was first installed in the early 50's, the local electrician turned TV-specialist had installed a ground wire, but with an interruption of about 1 mm in one spot. The theory was that it would let lightning jump that gap but would avoid "ground interference" on the TV. And one morning in 1978 we got hit by lightning. The top antenna got significantly damaged, one of its reflectors was found in the neighbor's yard across the road. The lightning energy entered our electrical wiring through the antenna preamp and through our old TV (we had unplugged our brand-new color TV a few minutes before the strike). The damage was very strange... A few light bulbs looked intact from the outside but the glass "stem" that holds the filament was shattered. A few other bulbs had holes in them. Also a few random switches got shattered. and 2 of the 3 large service fuses at the service entrance got blown (we had 3-wire service as we had a workshop). Of course the old TV and the antenna preamp were dead. I don't think we had any other significant damage, but was was remarkable was mostly that the damage was very odd and seemingly unpredictable.
