The RG-142U silver plated teflon insulation coax will easily handle 300+ watts at 900mhz. I would not make a 40foot jumper from it as it will get lossy when used in lengths over 10feet. I use it everyday to jumper autotune combiners to antenna feedlines at a combined power level of 300 watts RMS. The peak power being handled is 4 sidebands with just over 2000 watts PEP. It barely gets warm. I use it at 1KW in my shack at 30mhz. Remember to use Gold plated center pins and silver plated outer connectors when connecting this up. The Motorola part number is PK-610.
