Patent ID: 7761069

Claim:
A method for providing reduced antenna radio communications, comprising: when a first receiver of a first Line-Replaceable Unit (LRU) is operable, activating a first transmitter of a second LRU; when the first receiver of the first LRU is operable, connecting the first transmitter of the second LRU via a first passive hybrid combiner-splitter of the second LRU to a first antenna, the first antenna being communicatively coupled to the second LRU; when the first receiver of the first LRU is operable, transmitting a first signal from the first transmitter of the second LRU to the first antenna, the first antenna being communicatively coupled to the second LRU; when the first receiver of the first LRU is operable, receiving a second signal at the first receiver of the first LRU, the second signal being transmitted from a second antenna, the second antenna being communicatively coupled to the first LRU via a second passive hybrid combiner-splitter of the first LRU; and when at least one of the first receiver of the first LRU and electronics of the first LRU is disabled, re-routing the second signal transmitted from the second antenna via the second passive hybrid combiner-splitter, then to a first bypass relay of the first LRU, then to a second bypass relay of the second LRU via a crosslink connection, the crosslink connection communicatively connecting the first LRU with the second LRU, then to a second receiver of the second LRU, wherein reception of the second signal by at least one of the first receiver and the second receiver occurs concurrently with the transmission of the first signal from the first transmitter.
