To the best of my knowledge, nothing really works except fencing. A
neighbor across the road has an open permit that lets him shoot as many
deer in his resident herd as he needs to keep them from destroying his
corn crop. for years, he had a propane cannon rigged to fire
periodically, but after a few weeks the deer just discounted this.
Local vineyard.s have gone with 8-foot-high fences to protect their
grapes - may be the only way

Any suggestions on how to keep deer out of the yard and away from the
antennas? Pesky animals are always snagging my top loading lines and
bending the vertical.

Plastic owls and rubber snakes work for some folks but are not universally
successful.
Ultrasonic emissions have a much higher success record. Ultrasonic waves are
easy to "beam" directionally which permits a ground or near ground level
installation with the transducer(s) aimed up to where the birds like to
perch. Aiming the sound upward keeps from disturbing the dogs and cats.
These devices are available COTS for relatively little money or easily built
by the electronic savvy. Mine have lasted for many years and still work
well. Some of these devices offer choices on the type of output. A
randomly occurring warble tone similar to the "yelping style" public safety
sirens (but of course in the ultrasonic spectrum) seems to work best. Having
it come on at random intervals works best and keeps the birds from getting
used to it.
Inexpensive "tweeters" of the horn variety work well, especially if the
design lends itself to accepting a drain hole for water (well... it is aimed
up) Alternatively an enclosure with a hard flat reflective surface to aim
the beam upward will work.
I have used these for many years with great success, not only for birds but
other pests as well when coupled with IR motion detector including cats and
dogs who used to think my yard a public restroom and the odd skunk, raccoon,
armadillo, or opossum.
