Shouldn't a wrister go farther ???? * need bigger weight ? How high are you trying to go? With everything in my favor (wind, etc.) I could get over about a 50 foot branch with a wrist-slingshot and a 1oz weight. And I think I was standing on a 12 foot ladder to do it, and this was a "best ever" shot. SNIP Tim. I couldn't get 50 feet with mine. I figured the line was too old, but I realized the sling was way overrated. I can do much, much better with a rod and reel. My favorite tool was a Bear 76er Bow and Arrow with a short string. It had a 50 lb pull and I could place an arrow with a screwdriver handle on the tip where ever I wanted it. The best was a converted shotgun. I took a shotgun shell and took out the shot, folded the plastic outer shell over the inner shell and stuck a wood dowel into it. On the far end of the dowel was a screwdriver with an eye hook onto which I tied a string. It cleared a 100 foot tree with room to spare, but I was afraid of the possibility of damaging the gun itself so I only tried this once.

I wouldn't be so much scared of damaging the gun, but instead of the gun blowing up in my face! The tennis ball cannon I use is very very similar to the CSV19 at http://www.antennalaunchers.com/ and I am very very happy with it. It's not so much a "point above a crotch in the tree and hope the ball goes through" but "just shoot the ball and line over the tree". Tim. |

Wouldn't that be damaging the gun? The dowel I used in the barrel was a bit smaller so it wouldn't get jammed. I imagine if it were a larger diameter, it would have traveled further. Completely filling the barrel would make me expect an uncontrolled explosion... -- 73 for now Buck, N4PGW www.lumpuckeroo.com "Small - broadband - efficient: pick any two." |

The "air valve" for it is off-the-shelf so it's a plug-n-play project. It beats every fishing rod, bow & arrow, sling shot..... anything I've ever tried before. Beats them hands down. It'll easily clear a 100 foot height and is accurate after you shoot it a couple times. It's a little pricey but that could be spread out if it were to become a club project. Kingfish |

My impression is that the CSV19, with its modified sprinkler valve, has a higher muzzle velocity than the QE-19. But overall, I agree 100%, that for me the tennis ball launcher was far and away the best choice. I have some friends who are very good with crossbows and they tell me that I'm wrong, that the crossbow will do the job more reliably and accurately than my tennis ball cannon, but I don't have a crossbow and don't really intend to learn how to use one. I don't really want to shoot arrows into my neighbor's property either. The tennis ball cannon just made the job so easy, and literally the only gotcha is that you'll not only send the ball over the target tree, but probably the trees behind it if you aren't careful. One trick I learned very quickly: When you see the ball go over the target tree, grab the fishing line and stop it, then let it go so the ball can just fall from there. My trees are at the very edges/corners of my property, and using this trick I was able to ensure that the support lines are also within the property. Tim N3QE |

Tim N3QE A lead weight from a slingshot or an arrow from a bow will clear most anything if the string is set up correctly. But both are fairly dangerous coming down if the string breaks. That's the good thing about the tennis ball cannons, I think they're safer. I chose the QE-19 because the components were off-the-shelf and required no modification. Kingfish |

I don't really want to shoot arrows into my neighbor's property either. A very important point. In many areas, firing a crossbow (which is generally perceived as a lethal weapon) at anything other than a designated target would set you up for a lot of hassles with the local constabulary, or worse. The tennis ball launcher (avoid the "cannon" term..) looks less "weapon-y" |

Wander around aiming that thing at the top of your trees while the gendarmerie rides past and I'll bet you'll be asked to "DO IT NOW". Just for added effect, when I made my tennis ball launcher I spray- painted it yellow and then added black stencils with BIOHAZARD and FALLOUT SHELTER symbology on. And then I stenciled BUTTERCUP on for the opposite impression :-). I'm sure that some people are comfortable with lead weights flying through the air, or with crossbows. Me, I just happen (perhaps through lack of ability with the other two - I tried, but failed with slingshot and crossbow, but the tennis ball cannon worked the first time!) to be pefectly comfortable with the tennis ball cannon. And it worked, man it worked. I am so so so happy with the resulting antenna, 100 feet up between two trees. Tim N3QE |
