Sure, drive the second antenna through a section of feedline from the first
line.

Not as easy as it sounds. It's a juggling act between phase shift and
impedance matching. Reference: "The Simplest Phased Array Feed System

I've used this design a fair bit, it works nicely.
Look under "Well, how do I get a directional bearing"
