Work/Plans continue on 866 MHz 15 element. THink it is not that difficuct - try Google for
Yagi-Udi Antenna and I think you'll Have Joy.
Generally Driven Element is 1/2 wave, reflector is + 1/8, 1st director is is -1/8, every other refelctor is -5% of 1st reflector.
Spacing is 1/8 wave for 1st Director and Reflector and 1/4 wave for all addition reflectors
though 2nd through X relectopr spacing is not critical, within reason, for Receive Only Applications.
(If you figure 300/MHz you get Wavelength in Meters, in case you didn't know... )
BE SURE the Driven Element is disconnected from the other elements in a Yagi.
"It is far easier to make a "side-scan: than an "end-fire" array with a Yagi-Uda"
Not abad thing for receving ant... If they turn out to be side scan then just build two with switch! That's the current plan here.
In the 11M band I find it is "far easier to build a boozuka" i.e. shoots out both ends with
"Moon-Raker" 4 -element X 2 horz/vert. But this is a transmission array and not an 800 MHz receive-only array....
