N3JNC 3 Element 2 meter Yagi Fox Hunting Beam
antenna is very easy to build. Materials are some 1/2 inch aluminum
tubing, 3 cold water pipe grounding clamps, 6 wing nuts, a 1/2 inch hose
clamp, a cable TV ground block and a 75 ohm matching Transformer (This is
just for the F threads to a solder stub and will be put into the ground
block in place of the F81 (aka barrel). A small piece of #14 copper
wire, solder, and a small piece of hardwood dowel that has been lacquered
to prevent moisture from turning the wood into a conductor.
This antenna is 75 ohm and I feed it with 75 ohm RG 59 CATV feed line. This goes to a BNC connector that attaches to my HT. My Kenwood HT has worked fine with it for 10 years. I get a good swr with this set up. Close to a 1:1.1, I have used it for receive and transmit for many years now. It probably has a better match than the HT's rubber duck.
If you are really worried about the match, I'll show you a gamma-match that I used on five element Yagi I built based on the same design as this antenna. The gamma-match will give you the 50 ohm feed point and works great.
But if you are using and HT, this will work fine.
