This router is a router with a 4G modem and an irradiator, integrated in one case. The router has several types of mounts that are included in the package. The self-amplification of the feed is 8–9 dB. The range of operating frequencies lies in the range of 1700-2700 MHz. MIMO technology, supported by the irradiator over the entire frequency range, doubles the channel capacity. The device runs on the OpenWRT operating system, which provides bandwidth allocation (QoS), a firewall, user access control and many other features.

A feature of the kit is the presence of a SIM-injector in its composition. It makes the process of installing and replacing a SIM-card more convenient and faster. A LED indication is displayed on the SIM-injector case, which displays the main parameters of the device. On the router board there are two slots for installing SIM-cards. Thus, in case of problems with the first SIM card, the second one will provide uninterrupted access to the Internet. It should be noted that despite the remote location of the SIM injector, the communication quality does not deteriorate.

The built-in 2.4 GHz WiFi antennas support 802.11 b/g/n standards and provide communication in a radius of up to 50 meters at an open range.

The following installation options are available:

  • into the offset (parabolic) plate (the offset plate itself is not included in the delivery package of the router);
  • on the mast;
  • on the wall;
  • on the table or window sill.

Advantages of the Kroks Rt-Pot sHw:

  • the SIM injector (optional) provides ease of installation and replacement of the SIM card;
  • there are no microwave assemblies, adapters, connectors on which signal loss occurs and, consequently, Internet speed drops;
  • easy to install: to install the device, you need to lay only one cable - a twisted pair cable, which is much simpler, faster and cheaper than laying two microwave coaxial cables;
  • the cable length from an external router to an internal WiFi access point or computer can be up to 100 m;
  • to power the router, you do not need to mount a separate cable, since the power is supplied through a twisted pair cable ("+" is supplied on a 4-5 pair, "-" is supplied on a 7-8 pair). A power injector is already included with the device;
  • ability to connect 3 SIM cards;
  • stability at temperatures from -30 to +60 degrees
  • built-in 2.4 GHz WiFi antennas support 802.11 b/g/n standards and provide a communication range of up to 50 meters at an open range.

Inside the device, a Huawei E3372 modem is installed.

The router has one 100 Mbps LAN port.

The dish+irradiator system has a very narrow radiation pattern (beam angle of 2-3 degrees), so guidance requires special accuracy. Deviation of 1 degree reduces the signal level by several times.

Installation of an irradiator.

The gap between the pressure lead of the irradiator and the plastic tube of the bracket is 6 mm. Be sure that the illuminator fits the design of the cymbal holder in advance.

Clamp the irradiator in the plate holder. Most 4G internet operators use X-polarization of the radio signal. To find out what polarization of the signal your 4G operator has, you need to try turning the illuminator in the holder by 45° and look at the signal strength in the program on the computer. With the wrong choice of polarization, the signal level will drop by 30 dB or even more.

Point the plate to the tower. For this, the arc from the plate to the irradiator must be directed exactly at the 4G tower of the operator. It may seem that the plate is "looking" at the ground. In fact, it receives a signal from the direction where the arc that holds the irradiator is directed to. If the tower is far, then the arc will be approximately parallel to the ground.

The dependence of the gain on the diameter of the plate (approximate data):

Diameter of a plate, meter 0.5 0.6 0.8 0.9 1.2
Gain, dB 23 25 27 29 34

The antenna's own gain (without a dish) is 8–9 dB.

Note that any obstructions between the operator’s tower and the illuminator will attenuate the signal. It can be trees, houses, structures, uneven terrain. Therefore, choose the installation location of the plate so that as far as possible the direct visibility of the tower.

The larger the diameter of the plate used, the higher the gain. The higher the operating frequency, the higher the gain.

ATTENTION! Satellite dish not included!
