If they are of the K1FO 25 element design, you can find all info at https://directivesystems.com/432-mhz/dsefo432-25/
Looks like E-plane stacking distance (side by side, horizontal polarization) is 5' 10' while H-plane stacking (one over the other, horizontal polarization) is 5' 6".  At this frequency using a 50 ohm power divider would be the "best" way to go as then the only requirement for the two phasing lines is that they are 50 ohms and are equal length.  
For roving, my thought is that this is a lot of work and hassle for 2.5 dB (unless your doing EME), but, sounds like a fun project and as always YMMV !
