hi,
if you swap the two antenna feeders of sector 1, there is no effect.
if you connect the TX or the RX of a TRX of sector 1 into the combiner of sector 2, then you have a problem. This TRX will be logically in sector 1 but will cover sector 2’s azimuth.
if you swap one antenna feeder of sector 1 with one antenna feeder of sector 2, then you have a problem : half the TRX of one sector will have their TX in the other sector.
