    it happens if you have a crossed feeder towards the antenna.. check it simultaneously.. I mean, have someone upstairs to check the feeder connection.. try to do DTF with a dummy load to see which feeder you are testing. if he picked the wrong one, of course you will get a VSWR of the whole antenna system.. so you’ll have to do it 1 by 1.. the cell A TX/RXA leg is not paired with Cell A RXB. it means the right diversity is paired with the other sector..

    sure it will come back. so better have sitemaster or equivalent in troubleshooting.. it makes also handy when you have a netmonitor to check whether your BCCH is on the right sector/cell.. have fun! goodluck

    It worked out.It was an RDU with so many cables.I spent like 3 hours to trace the correct cable.Some other cable was attached to the antenna 🙂
