help me understand here.I built a pneumatic tennis ball launcher for putting up antennas. At 100 psi, I can put a tennis ball through 3/4" plywood (NOT OSB) at 40'. I also utilize it to chase the neighbor dogs out of my yard,
I have three tennis balls that have been modified with a stainless steel loop through them and some additional interior weight (bb's). I tie heavy string (usually fish netting line; approx 1000lb breaking strength) to this loop before inserting the ball into the launcher. I then shoot this modified ball over the tree to get the string over the highest branch possible. Once the string is over the intended branch, I pull up a long wire antenna, or other line to help with guying, etc... This used to be done (and still is in some areas) with a bow & arrow setup, but many people like tennis balls better as they have more "bounce" than an arrow. And yes, I have broken the netting line a couple of times and lost tennis balls (I used to have 6 premodified ones).help me understand here.I built a pneumatic tennis ball launcher for putting up antennas.

How does a tennis ball launcher assist with putting upan antenna?
You can put a tennis ball "through 3/4 in plywood at 40ft". holy crap.
You're shooting this thing at dogs? Seems to me you'd kill them.
