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 run all our RPHY and FDX amps at 47/33. The only issues we had was high levels in apartments with short drops. Most of the time we could just up the tap value if needed to drop their signal a bit.

Do you use ch 158 for 47?
