Here is the rule: The horizontal distance between antennas should be greater than 1/4 of its wavelength (absolute minimum separation), but it should not be located at the exact multiples of its wavelength (maybe avoid the first 3-4 multiples).

How far apart should two antennas be?
For a system consisting of a transmitter operating at 10mW and passive omnidirectional receive antenna, a general rule of thumb is to maintain at least 3m of separation between antennas so as not to overload the input stage of the receiver.
How close can I mount two antennas?
Distance between antennas
The distance between the two diversity antennas should be at least one quarter of a wavelength, and the distance between them will affect the signal.
What happens when antennas are placed too close together?
When installing a cell phone signal booster system, antenna separation is important because when the tower (outside) antenna and device (inside) antenna are located too close together they will pick up each other's signals and create a feedback loop – a condition called oscillation.
How far apart should MIMO antennas be?
Spacing them 3 feet apart is great and facing one tower you will get MIMO, pointing to 2 towers will also work because you will get signal from the best tower (MIMO will figure out which one is best).
