My ham father built and uses one functionally similar to this one. It's slightly more involved than using a wrist-rocket/slingshot but it's also far more effective at reaching high branches.
- mungoman2 3y agoCurious how you get the equipment down after you're done?
- voxadam 3y agoYou launch a ball tethered by a spool of fishing line over a sufficiently high branch, locate the ball, remove the ball, attach one end of your dipole antenna to the line, pull the line back at the gun side until the antenna is in its desired location, cut the line, and finally secure the line to a tree trunk or other anchor point. Then, you do the same thing with the other end of the antenna. The the antenna's feed point and balun[0] is located at the midpoint of the dipole which is connected via coax to the tuner, amp, and radio. When you're done with the setup (e.g. field day[1], camping, etc.) you simply cut the anchor and lower your antenna down one end at a time.
