	I'm not sure this is applicable to your installation or not.  For 
~25 years I've fed most of my Beverages from a single point (in a 
star configuration).  I use one transformer, one ground rod and small 
reed relays to select the desired Beverage wire.  My Beverages are 
all terminated so the unused wires are all grounded at the far end 
through their termination resistor.  This arrangement has worked very 
well for me over the years.

P.S.  I can also select multiple Beverages simultaneously which is 
sometimes useful in contests (i.e. ~3 dB loss due to impedance 
mismatch and probably some degradation in pattern).
