multi-element horizontal omni

http://home.comcast.net/~ross_anderson/HOCollinear.htm

The spacing of these antennas is so close at to make it hardly worthwhile-
as Tam points out in a following post. For simple omnis, or dipoles, the
stacking gain peaks around 4'--5' at 2M. A first shot at modeling shows
that the gain increase from stacking 2 omnis at 27" is around 0.5dB-
assuming a lossless matching network.
