[50mhz] High SWR on a 4-element beam

[Ray Brown]

  It wasn't lightning. The rotor cable got chewed up by a lawnmower because it had
dropped down to the ground and I didn't know it and my son chewed it up. :-(

What caused the rotor cable failure?

If it was lightning related that could be the cause of the antenna failure as well.

Could be a damaged matching device on the antenna....or damaged feedline.

Hard to know without more info.
