If you can't find that, LMR-900 is the same weight per meter of cable. Slightly higher loss though.
At 2500 MHz the commscope cable loss is 9.14dB/100 meters of cable loss, the LMR-900 is 9.8dB. https://www.timesmicrowave.com/documents/resources/LMR-900.pdf That can get costly quick, you're looking at $3.50 to $4/ft of cable.
