70cm 28 Ohm Yagi
On this page are designs for 28 ohm 70cm Yagi antennas.  The 28 ohm driver impedance gives better patterns and bandwidth.  They have a matching network to 50 ohm, that is composed of 2 - 1/4 wavelengths 75 ohm coax in parallel.  These are high performance beams designed for SSB, to put them on FM make the elements - 2mm shorter.
