Thanks for all the guys who fielded questions on the grounding topic. Had the final inspection today and the guy did not ask a single question about it. So I guess he saw what he wanted to see. 73/je

For the 50 vs. 50a question, it's actually possible that 50 predates the internet. The coax I have has been setting in storage for probably 20 years and I have no idea when it was actually made. May
