Trouble Shooting Batwing Antenna part 1

I was living full time in my RV. Originally parked in Phoenix. I was able to get good reception after replacing the coax cable. However we moved to Flagstaff due to the heat in Phoenix. Shortly after the move there was a big storm and it knocked out the translators. Of course I really didn't fully know this until I email an broadcast engineer at KPHO CBS5 answered my questions. Yes the antenna head had really poor performance. SO I replaced it. It fixed the problem.
