Yup. I was trying to emphasize that the most likely damage is coming through the power lines. Lots of people focus a lot on the antenna and the connectors. A cheap $4-5 power strip with surge protection will be the part that usually saves the system. If you don’t have one I definitely suggest you use one on all your electrical equipment.
It probably cost $30-100 to get the surge equipment and install it on an antenna. It cost about $5 for a power strip surge protector. 98%+ of the time the surge comes through the power lines or data lines.
You also have to remember that lightning goes to the lowest potential in the area. These are usually trees and power lines. Unless you have some extremely tall tower thing to put the antenna on, your chances of getting a lightning strike through the antenna is very low.
