[TowerTalk] Six meters and two meters same coax

[Drax Felton]

Can two separate horizontal Yagis for 6 and 2 meters on the same mast share
a common feed line?

I've seen this done on a Cushcraft dual band 2m/23cm Yagi antenna where both
set of elements were sharing the same boom.
They only used a coaxial tee to split the signal.

Where can I find information on what the side effects of doing this are?
