you should teal have an earth ground, as it is required in most cases for NEC codes, and if you violate those codes your home owner’s insurance can get out of paying for any damages if you have a lightning strike. When I took my strike here there was no investigation, but the damages were only minor electronics and a computer. not enough to send an agent. We he’d storm damage here a couple years ago which caused our ceiling to cave in in part of the living room and in that case they did send someone to asses the damage.. It also helps a lot with noise pickup and helps keep any strikes from causing more damage, like burning your house down.  It is a good reminder to me now that I got my hf antenna back up and running that I need to get a grind system. currently my feed line is outside unless I am actually on the air, which is something that I definitely recommend when not in use if you don’t have a ground, ground your antenna outside to bleed off static charges and keep the energy away from your home. obviously this is not a real solution, but until you get the ground done you should consider that. Wehen i took the lightning strike my feed line was grounded outside, something I had done no more than 3 minutes before the strike. I found pieces of my feed line scattered al over the yard, melted from the inside rout so fast that aloof the feed line was partially intact. it makes a nice display at our hamfest and at club meetings for safety.
