[NLRS] Adding a 6M Beam

[Andrew T. Flowers, K0SM]

Gerald,

Just a quick thought--did you try modelling the dipole running 
perpendicular to the 2m antennas' booms?  One would have to remember 
that the dipole has nulls where the 2m antennas are pointing, put you 
might be able to to a rotatable dipole without upsetting things too much.
