INTAS-S4-512
The INTAS-S4-512 passive antenna combiner allow four transceivers to be connected to a single antenna. Reducing the number of antennas on a platform reduces the visual impact and can improve the radiation pattern due to the reduced effect of co-site interference.
Successful integration of multiple antennas onto ground and shipboard platforms poses many challenges. Platform features impact antenna performance by blocking, reflecting or re-radiating energy, and co-site interference can impair the effectiveness of multi-antenna installations.
