I'm not sure I understand your question, do you want to achieve omnidirectional coverage or do you want to switch between antennas? It sounds like you are making a phasing harness so all the antennas will feed one piece of coax. In any case, mount the antennas a minimum of 1/4 wave length apart.

Keep in mind that you will have nulls in your omni pattern simply because of the electrical design of yagi antennas. This may/ may not make a lot of difference depending on the distance of those systems from you. Each yagi will have approx. 2 null zones. However by using low loss feedline these can be minimized.
