As the fastest 4G LTE mobile fixed router, Huawei B618 mobile wireless router is widely used all over the world. It is a LTE CAT12 router, of which’s download speed could achieve up to 600Mbps, twice of the hottest LTE CPE Huawei B525 router. However, not all of us could enjoy the maximum speed because it depends on many factors. As the following user asked at the Mybroadband forum.
Anyone know of suitable external antenna’s for a Huawei B618s-22d? I live in Helderkruin and signal is not the best using Rain Lte. I get 1 or no signal bar and maximum speed I have managed to get was 12Mbps. Looking at maybe adding external antenna’s to the router.
Yeah, the B618 router has the external antenna slots that are useful when we get the weak signal.

What Type of Huawei B618 External Antenna Connector?
Most of the people would ask the same question when they want to buy an external antenna for their mobile devices. All the questions are related to the connector type. Unlike the Huawei LTE Cube Huawei E5180, the connector type of the B618 is TS9 which means that the B618 router only accept TS9 connector antennae, no TS5, SMA , CRR9 or other types.

How to Choose External Antenna for B618?
There are so many LTE antennas online, which one is suitable for your Huawei B618? The most important factor is the frequencies supporting range by the router and the carrier. Huawei B618s-22d supports 4G LTE Band 1/3/7/8/20/38 (FDD 800/900/1800/2100/2600MHz & TDD 2600MHz) and the B618s-65d supports Band 1/3/5/7/8/28 (FDD 700/850/900/1800/2100/2600MHz & TDD 2300MHz). And you also have to know the frequencies your carrier adopts. For example, if your are a South Africa user who uses the Vodacom package, you should know its using Band are 900/1800/2100/5800Mhz. Then the antenna you choose should support the carrier’s frequencies. Not all of the antenna could cover all LTE bands.
Then other factors you may consider when choosing an external antenna would be the gain, mounting way, etc,.

Where to Buy Huawei B618 LTE Antenna?
