I've had this thing for several years and I can out up a wire
anywhere, anytime, in a few minutes. Why would you need anything
else?

Be careful, be very careful. There is a reason PVC pipe is not
allowed for distributing shop air. People do it out of ignorance or
because money means more than safety to them. Google to see some pix
of what shrapnel damage from exploding PVC pipe can do. Because
people aren't killed first time every time they pressure up PVC pipe
doesn't mean it isn't dangerous.
I bought a tennis ball launcher as a birthday gift for a friend. If
I recall correctly it is called a K-9 Kannon. It is made of plastic
and uses large rubber bands for launching the ball, ostensibly for a
dog to retrieve, hence the name. There are several models ranging in
cost from about $7.50 to $20.

Being the cheap ham that I am, I built one from the plans on that

a but a bit more robust.
I can launch a standard new tennis ball 250 meters at a ground level
target
and much taller than anything around here. I have ropes in 70 foot
pine
trees supporting wire antennas.
I hate the fishing reel that I'm using, so I should probably upgrade
the
reel.
There's some margin for safety built in, but I wouldn't inflate more
than
the recommended pressure with a PVC pressure vessel. A failure could
be
dangerous.
Be safe, a tennis ball could hurt someone!
