Try the plastic snakes on your boom too, to scare birds. It works...
Ill take temporary relief over nothing at all.

Bill, The boating community often recommends plastic snakes to keep 
birds from roosting and pooping all over your boat.  With over 30 
years of boating experience in the San Diego California region I 
witnessed lots of folks using plastic snakes.  You can tell the new 
guys at the yacht club by their  new plastic snakes.  Over time the 
birds get used to the snakes and totally ignore them. 
I know of no long term success with plastic snakes.  Experienced 
boaters I have known agreed that collectively we had never seen a long 
term success using plastic snakes.   Phony owls are also touted but 
they too lose effectiveness fairly rapidly.  I've seen birds perched 
on the owls head pooping on it. 
Geese and other birds have hearing that extends higher in freq than 
normal humans.  I say normal because in my mid 20's my left ear went 
to 21,500 Hz and my right ear went to about 20,500 Hz.  I could hear 
bats feeding, ultrasonic alarms, etc. Now I wear $6000 hearing aids 
from the VA thanks to small arms fire and other loud noises. 
Something that works and doesn't lose efficacy from birds getting used 
to it is ultrasonics used intermittently more or less randomly unless 
used with IR motion detector or other detection apparatus.  I have 
used ultrasonics very successfully to keep away various pests 
including birds.  Places with large flocks of geese have nice lawns 
"goose greased" so badly you can't walk through without getting your 
shoes messed up. I have recommended ultrasonics to lakefront home 
owners who had great success with repelling their Canada geese.  The 
geese soon learned to avoid that lawn and stay on his neighbors lawns 
farther from the transducers.  Word spread and some of his neighbors 
went ultrasound also with great success.  Only a few houses stayed 
unprotected, a couple were only used a week or two a year, did not add 
ultrasound (that I am aware of) but were partially protected by 
neighbors with ultrasound. 
Geese have pretty good ultrasonic hearing.  To them bursts of high 
levels of ultrasound is what having a steam whistle go off in our ear 
is like. Some ultrasound pest repellent gear has selectable freq bands 
so you can avoid bugging cats and dogs or include cats and dogs and 
they will avoid the area too. 
Decades back the lab where I worked had an oceanographic tower 
anchored to the bottom of the ocean just off the coast from San 
Diego.  Seagulls used it for a big bird perch and pooped all over 
everything on it.  Seagulls were captured and "lightly tortured" 
within limits of animal cruelty organizations and their distress cries 
were recorded.  These were played back at random intervals and worked 
pretty good but over time lost effectiveness.  You don't get used to 
pain from powerful ultrasound, it always hurts if you can hear it.

 Around here (south central Oklahoma) the gophers are bad about 
chewing up direct burial cables. Need to use conduit.  They don't 
seem to chew up PVC pipe/conduit. A notable exception is the direct 
bury phone lines with which I have never had a problem.
Since this not
 where squirrels are out, and the ground hogs appear to still be 
hibernating I think the
culprit is a goose.  The coax looks more like it is pulled apart 
than cut.
Has anyone had a similar occurrence?
 
Many folks don't appreciate the gooses bite.  They can bite quite 
hard and have a raspy insides to their mouths.  They bite down hard 
and then twist their heads.  Pretty vicious.
