Antenna for mobile router?

I'm looking for an antenna for mobile lte huawei router, who knows and can handle it

give me a hint! MfG thomas

Look in the internet under Google, there you will find many building instructions for such antennas

If you have too little reception strength, because you may live in the edge area of the next LTE mobile tower, an external antenna makes sense.

How mobile should it be? How big is your purse?

Stationary directional antennas:

If you only want to use the router stationary and want to have good reception, fixed Yagi directional antennas are the perfect one for you. There are open antennas, as you can see the antenna elements (bars). And there are closed Yagi antennas, there's then a kind of plastic grommet as protection placed over the antenna. Yagi antennas often have high profits, often 10 - 20 dBi gain. You need 2 pieces with TS-9 plug. The antenna cables have losses, so please do not use too long antenna cables. Also antenna cables with poor quality, make the reception gain again not. So low-loss, shortest possible antenna cables are an advantage.

Here is an example of a Yagi antenna:

"Mobile" omnidirectional antennas:

These typically only have 4 to 6 dBi gain. Often, the profits are a little frilly (up to x dBi) in order to differentiate themselves from the competition. Omnidirectional antennas are definitely better than the internal antennas of the LTE router, of course, need a suitable place and mobile, you can use such antennas only cumbersome.

Here's an example:

Note:

There are also LTE amplifiers, with gains of up to 50 dBi. These gains are totally useless with bad reception, because a bad LTE signal (SN ratio) can never be improved with a gain amplifier.

That An amplifier amplifies the LTE signal, but it also amplifies the interference, and worse, it adds some additional interference to the signal. LTE amplifiers only make sense if you have a good signal and have to transport this good signal over very long cable lengths (> 10m) to the receiver / LTE router.
