Being an amateur radio operator, I occasionally have to deal with equipment maintenance issues. I first noticed the problem when I found it difficult to communicate with several nearby VHF/UHF repeaters. Then, I noticed that my HF radio would not tune on 75 meters. I checked on all of my indoor cables and found no problems, so I ventured outside and noticed the following significant damage to my amateur radio antenna system.
Apparently, an animal had chewed through my VHF/UHF feed line. My dogs didn’t do it because it was outside of the fence.
There was also damage to the HF ladder line feed to my G5RV antenna. There were many visible tooth marks. The coax around the balun was destroyed. These components we’re well outside of the fence.
I used an auxiliary feed as a temporary fix for my VHF/UHF Yagi. I needed to obtain a new G5RV antenna.
Update: 3/4/2020
I installed a new G5RV antenna today. I also cleaned the corrosion from my feed line connectors at the balun. I was able to tune up on 75 meters.

Oh critter damage. When we built a friends shack in the northeast we found this wonderful conduit that we could run power, networking, coax etc. It was a nice hard conduit. It was blue and ridged. Great stuff.

And actually I’d used some. I once had a cat who my bad I trained to play with cables. So he’d chew through 50 conductor cables until I armored them.
