Topband: Checking the integrity of 75 ohm cable

[Gary Smith]

Hi,

I'm trying to discover if the 75 ohm coax 
to my Rx system might have been chewed by 
some critter. half is underground though I 
have had real trouble with moles at the 
site this year. I have 13 75 ohm coax to 
check out.

What would be an easy way to tell if these  
coax have been damaged in some way?

I do have an old MFJ-259B

Thanks & 73,

Gary
