Cold drink (keep it in the fridge until you're done!).

Nut (the metal kind, use one that fits your camera tripod).

I use a BNC connector to go on my ICOM IC-T7H.)

Connector (varies based on the hookup you use.Tubing cutter (Your local hardware store will carry these).Sharp utility knife (USE WITH CARE!!! IT HURTS IF YOU SLIP AND CUT YOUR FINGER!!!).About six feet of RG-58 or similar (50 Ohm) coax.Cable tacks (they are small pieces of 'U' shaped plastic with a nail on the side).Soldering iron (yes, soldering is nessesary).Some 1/4' (outside diameter) copper tubing (yep, the same stuff behind your refrigerator).Drill bit just large enough to let the coax through.A length of 2x2 wood (if you don't know what that is, go to a hardware store, they will know what it is.) for the antenna boom.You will need (dependent on the band you wish to build your antenna for):

(If you wish, you may download YagiMax, and the data files for these antennas here.) While it may appear these antennas won't work, build one and try it my first antenna (also my first homebrew project) was for 70cm, the first station I heard was a repeater 50-60 miles away. I figured the gain, front/back isolation, impedance, and other stuff that takes a rocket scientist to figure out, (or at least someone smarter than me, HIHI) with YagiMax 2.21.
