Thanks, John. ... I'll wait to see what the others say, but I was really 
worried there for a second.

Eventually, maybe I will replace it with 9913, but I hate to have my help go 
up there again right now if I don't have to.

Appreciate the vote of confidence.

for a 50 foot run that will be fine. I wouldn't worry about it. if it was
RG58 I'd say replace it ASAP but RG213 isn't that bad on vhf and for a
backup will be fine for uhf.
