Features: 1) The RF 50ohm radiating coaxial cable (leaky cable) is manufactured on argon arc welding, corrugating and slotting production line with the most advanced technology by slotting the holes along outer conductor axis 2) he evenly-distributed relatively strong radiating signal in the close vicinty of the cable along is axis make it possible signal transmission, across long distance in uncovered 3) There is two type for RF leaky cable. One is coupling type, the other is radiating type 4) RF leaky cable coupling type a) 1/2 b) 7/8 c) 1-1/4 d) 1-5/8 5) RF leaky cable radiating type a) 7/8 b) 1-1/4 c) 1-5/8
