To all...
I have a Hy Gain 3 element 10 meter beam the club can use for the 10 meter contest.
I also have all the parts to make 2 element beams
When the day comes that the telephone poles are installed we can think about larger fixed yagis pointed into Europe.
Roughly 5 db of gain can be obtained with a 2 element yagi utilizing a driven element - reflector combination.
Place the reflector .02 wavelength behind the driven element
This spacing will yield almost a perfect match to 50 ohm transmission line.
Only drawback is the front to back ratio is only 12 db, but the 2 element beam is the easiest way to obtain appreciable gain at a very cheap cost $$$
