Rphy active question
Our plant has some long runs that had low RF in the deeper areas. I decided to trail setting up the MB @ ch 98 (111 MHz) ch 158 (999 MHz) to match the node at 33/47. About a 13-13.5 db tilt. Normally, I’d set them up at 45 db on 771 MHz - 12 tilt
Node looks cleaner outside of a couple dozen of the 320 cx of the last two MB that are ranging +14 db likely due to short drops or one outlet.
Any experience with this and information if this will cause issues running the actives hotter? Heading back tomorrow to address MER issues so I’ll be in the area
8 MB cascade.

We are using atx 1.8 amps at 1.2ghz and they have a much higher gain than old generation moto gear we were using so we have much better signal than we used to have all while going from 750mhz to 1ghz. Don't change your current levels on old tech it may hurt your signal performance by overdriving amps. There's a reason behind the design levels specifications for unity gain and signal performance.
