"...easy way ..."? To change the phase, yes.... To change the pattern,
Probably not. The impedance changes with the phase relationship. Antennas
feed power to each other. Try searching for "Phased arrays".

If I have two antennas hooked up to a transmitter, is there an easy way to
very the phase to one or both of the antennas
to be able to change the pattern around electronically?

Thanks
