Weaker network signal?

[rbb1robert]

Has anyone noticed a loss of signal strength using kk ROMs?
I'm running AOCP kitkat for a couple of months.Lately signal strength seems a little weaker.It was fine for 5-6 weeks.
Opinions and suggestions appreciated.

I use slim kat ROM And the signal is excellent I could say that is better than jb.
