a friend picked up some coax, pre-assembled, from facebook. right out of the gate, that sounded scary. it is white, stiffer than lmr400, has 259's installed, and labeled as following.. Commscope 0216 9700851 10awg 125cmp(etl) c(etl) hns# 1010809 rev c eo22181. i dug around on the web and forums, wasn't able to turn out any results. best guess from all that is that it could be 75ohm indoor video or marine grade. it set his 1.1swr to 2.5. can anybody easily recognize this product or advise? many thanks in advance for information.
