F系列射频同轴连接器
SERIES RF COAXIAL CONNECTORS

F型连接器典型用于75Ω电缆分配系统，特别是CATV，广播电视网络，它既可用于有阻抗匹配要求的场合，也可用于非匹配场合。其特点是螺纹连接、插合方便、价格适宜。
F type joining devices use for 75 Ω cable assign system, especially CATV, broadcast television network, It can already be used for having impedance to mate the occasion required, can be used in not mating the occasion too. It is joined, inserts helping jointly that its characteristic is whorl , the price is suitable.
F型连接器可与国际上同类产品互换使用。FL10产品为M10X0.75螺纹，结构、性能与F型相同。
F type joining devices can exchange and use with the similar products in the world. FL10 products are M10X0.75 whorl, the structure, performance are the same as F type.
