Mix and match xbees?

Is it possible to mix and match different antenna types in XBees? i.e., pair a chip antenna Xbee with a wire antenna Xbee? Also, if one of them says “Digi International” and the other one says “Maxstream” can they be paired? They are all series 1. Thanks

That shouldn’t be a problem. Just make sure they’re all running the same version of firmware and you should be fine.
