I echo Merv's comments. Here in the US Southwest the main chewing culprits are Javelina and Pack Rats. Any "normal" coaxial cable of the RG-59 and RG-6 type, "zip" cord, or house wiring type cable is regularly and consistently chewed and/or cut in two by these animals.
I have found two replacements which have solved the problem in my installations. For coax, the PE covered and flooded 1/2" CATV hardline takes care of the coaxial cable requirement. For on ground or near ground Beverage wires the Rural "C" wire, as Merv and others have commented, is NOT bothered by the animals. Another distinct advantage to the "C" wire is its strength. I have a couple of long, phased, on the ground Bevs made of "C" wire. The wires are attached at each end with the regular wire holders designed for the wire, held in place by the ground rods. I place the ground rod "acorn" connector above the wire attachment to preclude the attachment slipping off. I put more than 100 lbs. of tension on the wire (yes, it is made to make LOOOOONG aerial spans on poles spaced as much as 600' feet apart) which keeps the wire tight on the ground. At contest time I walk the Bevs and place temporary risers under the "C" wire to make it a normal above ground Bev. This is all in an area which is frequented by grazing cows. When the "C" wire is on the ground the cows just walk on it. When installed on the temporary risers the cows (or strong winds) can push the wires over and it just returns to the ground due to the tension. There is no chance of the animals becoming entangled in the wire or the wire being destroyed.

I know for a fact that the telco drop wire does not appeal to chewers, I put down a BOG and in one days time it was in 4 pieces, due to mongoose activity, yes one of the fine imported species in Hawaii, Or it could have been rats, we have roof rats that will chew anything in sight also. The wire was teflon insulated, and they did not mind the teflon. but while clearing part of this 30 acres I ran across a long length of telco drop line that had been laying here since the 1980s, it was intact and in fine shape, no chew marks, dont know what the difference is but it the rodents did not take a liking to it. Above ground beverages have to be 10 to 12 foot up due to the hundreds of deer crossing the property daily. I used WD12 for those runs.
