I recently made a db4 and I get ok signal without an amp but I wanted to bring in more stations and add stability so I purchased a "used" amazon return RCA TVPRAMP1R which was $20 trying to save a few bucks I am not sure I am getting full or much performance out of it.
If the amp was working at a full rated UHF 20db I would see much better performance I believe.
Since this is a build antenna i do make modifications every time I take it out to work on it.
I am going to be trying again probably this weekend maybe later today idk..

I do get WMAR and that is the weakest I get but it comes in ok
It could be my testing conditions that allow WMAR to come in I am in my garage and I think I am getting reflections ..
a limitation is the antenna will be mounted in the attic not outside or a tower.
Also very important question I don't understand is the
NMdB vs the Pwr dBm
the NMdB is what I have been concerning myself with but with the distance to the towers being 55miles even though i have a pretty much clear line of sight being in Delaware and pointing to Philly which is 18 true 30mag I have disturbances that cause interruption.
During sunup is a problem for me too
At this point i am just trying to get all the philly stations to come in very well and stable during all times of the day and during at least moderate weather conditions.
