[TowerTalk] Antenna launcher found

[W0MU Mike Fatchett]

You can build the Air Boss or similar from parts at your favorite big 
box store and you will need a valve stem from the auto parts store.  
This is by far the easiest method I have tried and I had fun making it.  
It will fire the weights a long way up in the air.  The issue I had was 
finding the line where it came down as fishing line is really hard to 
see.  I would also suggest the spider wire.  While expensive relative to 
other line, it is super strong.
