A multiple radio and/or multi antenna chassis is described in some embodiments, along with methods of operation, and non-transitory computer readable media storing machine interpretable instructions to be executed on a processor to perform the methods of operation. Variants are described having regard to the use of one or more of the antennas for establishing bonded connections whereby one or more subsets of the antennas are coordinated to operate in concert to operate one or more connections for data packet transmission while reducing energy loss issues as between operating antennas. The approaches described herein can operate, for example, with a plurality of wideband antennas to provide a multi modem communications device that can be coupled to a master/primary data communications device.
