If you don't mind shifting your DIY attention to a home-brew 6m/10m vertical (perhaps a trap implementation), you might look at a triplexer like this that gives: low pass at <90 MHz for 10/6m; mid pass at 130-200 MHz for 2m; hi pass at 380-500 MHz for 70cm. Five Element Portable Hand Held Yagi - for 70 cm. 440-7. Seven Element Portable Hand Held Yagi - for 70 cm (37 1/2 " Boom) 146/437-10.

Alaskan Arrow LEO Satellite Antenna - 4 Elements for 2 Meters crossed with 10 Elements for 70 cm. 121.5-3.
