Fortunately, the state of California has not outlawed sling shots (yet). 1. First you want a Wrist Rocket or similar sling shot that has a brace against the forearm. 2. Second an open-face spinning reel. Mine was $0.50 at a rummage sale. 3. Two small hose clamps complete the assembly. 4. Recommendations from other people, which I found reasonable, is to use 4 lb mono-filament fishing line. It is a reasonable compromise between too heavy and too weak. 5. I use 2.5 ounce sinkers that are shaped as flat disks. I had too many 1 and 2 ounce weights get stuck in trees. They don't have enough weight to pull the string over rough branches. This is especially likely to happen if the string happens to rub in more than one place. The flat shape fits nicely in the pouch of the sling shot. Practice in an open area first. Also practice with some stones or other "disposable" weights. With the above, I can put the line over branches as high as 50 feet. A lighter weight would go higher, but see #5 above. If a tree is relatively open, then aim for a specific branch. If the tree has a lot of branches going in all directions, just go over the top of the whole thing. At one Field Day, someone else brought a compound bow, etc. He was also experienced in its use. He could put the line > 100 feet up. A series of heavier cords and ropes was then pulled up until a tri-band beam was suspended by a line between the tops of two trees. 73, Paul AA6PZ @ N0ARY-1.#NOCAL.CA.USA.NA ------------------------------ Date: 11 Nov 93 03:06:40 GMT From: ogicse!emory!europa.eng.gtefsd.com!howland.reston.ans.net!usenet.ins.cwru.edu!magnus.acs.ohio-state.edu!gratclif@network.ucsd.edu Subject: Discones & Polarization To: ham-ant@ucsd.edu nope. Discones are vertcaly polarized. there are few single feed antennas that are circular. If you are thinking about doing one of the ao's, then don't sweat it the downlink is circular. (you only need one side to be circular to eliminate fading) greg -- Gregory W.

To: ham-ant@ucsd.edu What, if any, fixed antennas would work best for satellite work? I'm interested in working some of the 2-meter/440 stuff. 73 Harvey, N1PHP hsattin@nectech.com ------------------------------ Date: 9 Nov 93 00:04:55 GMT From: organpipe.uug.arizona.edu!news@uunet.uu.net Subject: How do I broadcast?

In princliple you can't transmit unless you have an FCC license.
