For converting standard 3/4G SMA MALE antenna connections (see images for example)

to the TS9 antenna socket commonly found on Huawei and ZTE portable MiFi Devices.

This type of adaptor is particularly useful, since the high quality RG174 cable takes the stress off the 

delicate TS9 antenna connectors if the antenna you are using has thick cable.

95% of MiFi devices are TS9, please note that Huawei E5377 is in fact a CRC9 connection.
