Can you put 2 antennas next to each other?
Adding a second antenna can increase the signal path coverage and give you a more consistent signal. To accomplish this you will need a combiner or coupler that can combine the two antennas together. I would recommend that you use two identical antennas. This will ensure a balanced signal path and coverage.
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 should antennas be from each other?
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 close can 2 TV antennas be?
The easy answer is that you should maintain a minimum mounting distance of at least 1/4 wavelength apart for the lowest frequency antenna within the same horizontal plane. For VHF antennas, that translates to roughly 19 inches.
