One of my favorite activities in ham radio is building antennas. The antennas in the document attached have both been built and proven to be very good antennas. The 2 element wire YAGI will surprise you how well it performs.
OOPS!!! There are a couple of typos in the attached document.
1 = The length of the "B element" in the 30 Meter 2-element Yagi should be 51.25 feet and NOT 41.25 feet.
2 = The C distance (element spacing) for the 12 Meter 2-element Yagi should be 9 to 10 feet and NOT 1 to 10 feet.
Sorry about that. I think I need to clean my proof-reading eyeglasses LOL
