Huawei E5573 E5577 and E5377 External Antenna

Huawei mobile Wi-Fi hotspot devices are always the most popular among users all over the world for their stable and easy-to-use feature. Like the models of Huawei E5377, E5573, E5577 and more, many users take them for travel on the go. In order to get a stable access speed, choosing an external antenna for the Mi-Fi is a necessity like the following user:
I have a Huawei E5577 model and I always do a lot of long distance rail travel and am seeking advice on external antennae to improve internet access.
#1 Which 4G Antenna Connector Type for E5573, E5577 and E5377?
#2 Single or dual connector antenna, which is better?
#3 External Antenna Recommendation for E5573, E5577 and E5377

Which 4G Antenna Connector Type for E5573, E5577 and E5377?
When buying the antenna users would be confused about the option for antenna connector type. In general there are 3 types, TS9, SMA and CRC9. CRC9 is usually for Huawei 4G dongles, SMA is for the LTE CPE router, and TS9 is usually for pocket Wi-Fi. All the E5573, E5577 and E5377 are with two TS9 connectors which means you have to buy the TS9 connector type antenna for these mobile Wi-Fi.
Single or dual connector antenna, which is better?
There are two antenna slots at the body of the pocket router, one of the two are the main antenna slot which means if you only want to insert a single connector antenna, just insert it into the main slot. As there is another extra slot for you to insert an antenna, is there a necessity to insert an antenna with two connectors? Any advantage? Yes, those three Wi-Fi routers support 2*2 MIMO technology which uses multiple radios to transfer more data at the same time, so, inserting a dual TS9 connector antenna would be better for signal boosting.
