I think I know the answer to this question before I answer it.

My KLM 40 meter beam has decide to run a very high SWR.  Since the antenna is 
located at 200 feet I had to go up and use my MFJ at the coax sub leading 
from the antenna.  At that point the SWR was around 4:1 across the whole band 
and got higher out of the band.  The balun of course is a 4:1 balun, but 
inaccessable for testing unless I drop the beam a little and wrestle it 
around...not a pleaant chore since it since it is kinda large and heavy.  
I've done this once before.

>From the above SWR reading, does it look like a bad balun?  I checked all 
mechanical connections the best I could visually and saw nothing amiss.

By the way I took a pretty good lightning hit over the summer.  I have used 
the antenna since then, but could it have had the effect of 'weakening' the 
balun?
