Dear Pramod kumar gupta
Normally all operators in GSM using 7/8″ Feedar cable Most of the operator using Andrew cables That cables using two types one is plain in side path and another one is threded inside path . u can use plain in side path is benifit becose your getting very low VSWR value. In jumper cable used 1/2″ or 7/16″ . In feedar cable you use the conector V5PDM for male V5PDF for female conector in jumper cable to use V4PDM ,V4PDF .
