The tree climbers do the best job, as has been discussed.
I have used a tennis ball launcher with good results to put lines over Pine
tree limbs. Usually I try for something about 70' to 85' or so.
I have a lot of Pine trees in the yard (plus other trees) and several are
about 100' tall but it is not practical to try to shoot over them and to
string a wire antenna between them. There are too many limbs to deal with
below the wire and the amount of "waving" of the tree at the top can be
extreme.
The tennis ball launcher does a good job but it is very hard to get a line
into a real good position. It takes me quite a few shots to get something
that is acceptable. One problem is that even if the ball goes over the
correct limb then it might also go over some limbs in nearby trees. This is
a problem that is unavoidable for people in yards with a lot of trees.
There are ways to deal with this but it is a big nuisance.
Patience is a key operative word.
The tree climbers can get a line exactly where you want it, but as Jim says,
they can be expensive. But, after a few days with a tennis ball launcher in
a yard full of trees you may well decide to spend the money for a climber.

All of my high wires are rigged through pulleys by climbers. I've used
several over the 12 years I've been here. The smartest has been the
arborist, whom I still use when he's available. But because he's good
and smart, he's also very busy. They're expensive -- the going rate is
$850/day for a 6 hour day for the climber and his groundsman, and when
the trees are as tall as mine are (they're climbing at least 160 ft),
one tree per day is all they can accomplish.
