WB2MIC Sling Shot Antenna Launcher 
This is my version of the Ez-Launch antenna wire hoister.  

I bought a cheap fishing spinner (reel) in the hobby aisle of a Rutland VT department store.  The spinner was $5.97 with 180 yards of 8-lb test line already on it. A new Daisy Powerline Sling Shot sells for $7.99, but I already had one but it was in need of new elastic tubing which I bought as a kit that including the ammo pouch at Dicks Sporting Goods for $3.99.  Two hose clamps - $1.98.  One-half foot clear tubing = $0.49.  Three one-half ounce lead sinkers - $1.99.  I also bought two 1-ounce sinkers for $1.99.

206ft random wire up 60 foot tree
1st attempt: 1/2 oz sinker.  Sinker broke from fishing line taking off like a rocket!!!
2nd attempt 1 oz. sinker didn't clear the tree.
3rd attempt.  Absolute perfect!!!!  
A 206 foot random wire is up and running.  Using a Palstar AT1500CV antenna tuner the random wire works well on 160 through 10 meters including WARC bands.
