I have found that generally a B/G version appears to be a bit more sensitive
than a straight B version alone by a couple of dB hence looking for G
versions even though they are operating a B units, The distances being
covered around out local neighbourhood mean that we must optimise for best
signal and that extra couple of dB just improves our margins.
