Robert,
The tennis ball system has an added advantage. It isn't considered a
weapon.
In some jurisdictions, shooting an arrow or firing a slingshot is
considered the
same as illegal discharge of a firearm. I cleared it with my local
police here in NJ... who inspected the arrow (without head) and
string attached,
before pronouncing it was not a firearm in their view.
They recommended that the downrange area be managed.
Which means... no solo antenna work.
I've experimented with bolts in place of target heads on the arrow.
It minimizes
the chances of sticking into a branch. But it's still dangerous, if
someone were hit
in the head by the thing.
