电缆结构:
内导体：
50 Ohm电缆：
柔软型（F）-铜包铝(1/4” ,3/8” 和1/2”F型);紫铜管(5/8”,7/8”，和1″1/4 F型); 皱纹紫铜管(1″5/8F 型)。
超柔软型（SF）-铜包铝(3/8″& 1/2″SF型);皱纹紫铜管(7/8”SF 型); 铜丝(1″1/4S F型)。
极柔软型（XF）-实心紫铜(1/16″& 1/4″XF型); 铜包铝(3/8”&7/8XF 型)
75 Ohm 电缆:实心紫铜(RTC11类)或紫铜管(KX6类 )
绝缘：发泡聚乙烯或普通聚乙烯(只适用于KX6类型) 绝缘。
外导体：
50 Ohm电缆:皱纹铜管
75 Ohm电缆:铜编织
外护套：低烟无卤护套。
