    Hi All

    What could be the consequences of Intra Sector swap.If the cables of Tx and Rx are swaped no calls i suspect.

    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.

    regards

    i don’t know what kind of antennas you are using, but usually there are no “tx” and “rx” feeders towards the antenna.
    each feeder contains a “mix” of tx and rx signals, from several TRX.
    anyway, if you invert feeder A of antenna 1 with feeder B of antenna 1, then there is no problem. It’s exactly the 1st scenario I described in my previous answer 😉

    cheers

    i think pix is right,as you can connect the TX/RX & RX feeder of the same sector to any port of the two ports of the antenna

    kamoli, thanks for the support!

    but you should be more assertive: “I think” should be “I confirm” 🙂 If you hesitate, then they will eat you alive! 😀

    Hi DK,

    As I understand, your query is like you have the RX and TX cables of more than one TRX swapped going to the combiner unit(assuming that the Transceiver module is not a Dual TRX).

    If this is your case, then there might be some issue on the RX Diversity. This could result to bad uplink quality on that cell that may lead to more drop call.
    You can still make calls on the cell.

    rgrds.

    My bad folks actually its me who’s living in ancient times.I was talking about the old antennae used to be deployed earlier having one TX/RX cable and one RX cable for diversity, now we have antennae with both cable capable of TX/RX so as pix said there would be no issue with swapping them.

    DK,
    it’s exactly what i thought (that you were living in ancient times!)
    well, you can now enjoy the present as if it were your future! how mind-blowing!

    cheers 🙂
