X-014
I put a 20" X 36", 2 by 4 inch mesh reflector 4 inches behind the X-011 and got a little bit more gain out of the design. 13 dbi versus 12 dbi (or less for the same frequency) for the Fracarro P54.
For a 12 dbi antenna, it has a very wide beamwidth. This 3D beamwidth pattern is at 585mhz, channel 33, the middle of the new UHF band. It also appears to be a fairly forgiving design, spacing-wise. This could be a very cheap and easy antenna to build using electric fence stand-offs that are made for chain link fences. (available at Tractor Supply)
