Anyone ever have the matching network apart on one of these.

The one on the North side of my shop failed recently.   I have no idea 
what happened other than when I went to use it night before last the 
local repeater which is only 6 miles NE was barely audible.  SWR was sky 
high.  Everything out tot he antenna appeared to be fine. So I swapped 
it out with the spare and SWR is now good and repeater is full scale on 
the receiver.

I pulled the sheath off and the elements appear to be fine.

BTW my max power from the shop is 50 watts on 2-meters, although that 
antenna is rated for more than 300.
