10m length of H155 with an N connector
Hi Bill,
the attenuation of your H155 is about 5db @2400 MHz and i guess the N Connector is a cheap part from LingLing (here for cheap chinese goods). So you only have 1/4 of the power on the feed. The H155 is not usable for 2400 MHz. The RL is only 15db @2400 MHz (SWR 1,43) Look at datasheet from Belden.
