In a LTE SiSo DAS where the RRU ports are combined in a hybrid combiner and distributed though a building on coaxial cable to multiple antennas via passive couplers and splitters.
Should the TM (Transmission mode) be set to TM1 (single antenna)?
Would the TX signal be degraded (EVM) if MIMO / diversity transmission modes where combined in an RF conducted setup (DAS) and not radiated in separate antennas?
