I have ldf-450 on my 2 meter array. Good cable but a pain in the ass to work with, doesn't go round corners well .You end up with a patch cable at the antenna so you can rotate and another cable at the radio. with a 100 ft run would you have less loss ,with the four extra connectors and patch cables ,than a single length of 9913 straight into the radio and antenna.? On the same note , the multicore cable tends to be more flexible than the solid core. And 9913 is more than enough at 27 mhz unless you plan on running 300 ft.
