[NLRS] Adding a 6M Beam

I ran a simple check in EZNEC. I had a 4 element 2m beam set of data, so
I stacked a pair a wavelength apart, then scaled (roughly) those 4
elements to a 6m beam between the pair of 2m beams. Caused the 45 degree
lobes I forecast, and cost 3 dB forward gain, e.g. the stacking gain.
Killed the front to back making it 3 dB instead of 20 dB. Longer yagis
like the 13B2 may be more picky, though I have little confidence in any
CC gain claims. Longer yagis tend to be pickier about their environment
than 4 element yagis.
