Been going all over the place today. I started around 5am and modified Chang Puak's Yagi-Uda calculator to suit my needs. I needed to add elements and his first calculator had that, but didn't show dipole length and his new one didn't allow for adding elements. So I merged the two a bit. Can be seen here.
I believe I'm going to build a Yagi-Uda antenna to do a little fox hunting on the repeater I frequent. We have two jerkoffs that want to cause chaos on the frequency I figured I can do a little dox'ing to return the favor. I also bought a 20$ SDR to do a little testing with.
