RTWP issue on 2nd carrier only

[Henry1014]

Dear all experts,

3G site having 3 sector, each sector has two carrier which are F1,F2, I found out the sector 1 (f2) having constant high RTWP value (around -90) all the time. But F1 is fine. VSWR =1.29 and CPICH power =34db, RRU frequency scan has performed and its seen normal.

Please advise is there any other idea possibilities to reduce this abnormal RTWP ?
Your help is highly appreciated.

Thank you very much.

Hello m8,

Check the implementation of the site first, feeders etc etc.

Did you try to make a DT? I would start with a DT and a parameter audit on that sector
