Jeff,

Number of  	1/4	1/4	1/4	1/4	1/2	1/2	1/2	1/2

Antennas   Z ohm 	D/d  	D/d  	D/d  	Z ohm D/d  	D/d  	D/d 
2:1 		35.4 	1.67 26/15 31/18 	70.7 	2.98 	26/9
31/10
                   	 mm    mm                mm    mm  

So with 2 antennas and a 1/4 wave splitter you need an impedance of 35.4
ohm, D/d is 1.67  26/15  31/18 are common metrec diameters wich are
available here.. 

With a 1/4 wave splitter you need an impedance of 70.7 ohm  D/d = 2.98 


    Z0 =138log10{1.08*D/d} 


    Z0 = impedance l/4 line 

Where D = inside dimension of outer conductor

and d = outside diameter of inner conductor

I forgot to mention for a 6 port divider you can ony build a 1/2 wave
splitter with 3 connectors at each end.

Impedance should be 40.8 ohm

Quare of (100 x 16.66) 

You need to transform 3x 50 ohm parallel = 16,66 ohm up to 100 ohm (each
end) these 2x 100 ohm in parallel will give 50 ohm again. 

D/d = 1.83 

Z = 138log (1.08x1.83) = 40,83 ohm
