Have to wonder if this compact and powerful battery pack would suit your needs.  Affordable lithium.

[Cable types and losses]

I'll add my 2 cents for Corey and JohnE regarding the 90 degree coax connectors.  I am retired from the cable tv industry and I will tell you that we started using the 90's for cable management benefits but soon found out that we were experiencing far too many signal failure and signal strength loss issues to continue on with them.  We ended up doing a massive rewire to remove all existing 90 degree coax fittings in the plant. My hands experience with those issues says I will never install a 90 degree fitting in any of my radio coax connectivity.  Too many opportunities for failure and equipment loss.
