Can antennas be too close to each other

[BCasto]

With limited space, I have set up 3 scanner antennas close together. They are about 12 to 24 inches apart. Each is a single element 16 inches tall with a metal ground plane about 12 inches square.

Will their proximity interfere with reception, diminish signal strength, etc.?

I have multiple scanners each with a devoted antenna. I mainly listen to trunked digital systems in the 700 and 800 Mhz range.

Thank you.

You're fine.

An RFI issue and subsequent isolation concerns are needed when one or more of them is used to transmit.

Unlikely you'll have an issue.
On lower frequencies, it is entirely possible that it could be making them slightly directional, but since you

mainly listen to trunked digital systems in the 700 and 800 Mhz range.

The spacing likely isn't an issue.

Ask how it's working for this guy!

Thanks all for the quick responses. I appreciate it. I have a long way to go before I start looking like the car pictured
