It happens if you clean install the ROM, meaning wiping the data as well. In order to fix this, format everything except External SD Card using TWRP, and install Resurrection Remix ROM build date 20161119, boot the phone and then go to recovery after successful boot. Now, only wipe Cache, Dalvik Cache and System, do not wipe data. Install the ROM and gapps and clear cache and Dalvik. That's it. You'll no longer notice the signal drops.
Note : I chose 20161119 RR build because I have noticed that the signal quality is way better than any other custom ROM build.
