Kroks AP-221M3H-Pot - is а router with 4G m-PCI modem and a feed horn integrated in one body.

The proper amplification of the feed horn is 8-9 dB. The operating frequency is in the range of 1700-2700 MHz. MIMO technology, supported by the feed horn over the entire frequency range, doubles the bandwidth of the channel. The device runs under the operating system OpenWRT, providing bandwidth allocation (QoS), firewall, user access control and many other features.

The router has several types of mounts and can be installed:

  • in offset (parabolic) dish (offset dish is not included in the scope of delivery router);
  • on the mast;
  • on the wall;
  • on the table or windowsill.

Advantages over traditional solutions:

  1. the device already contains 4 components, which are usually purchased separately: the feed horn, the microwave circuit from the antenna to the modem, modem and the router;
  2. mPCI modem allows you to get the maximum possible speed 4G Internet that may not always provide a normal USB modem;
  3. due to the fact that the feed horn and the modem are installed as close as possible to each other, the loss in the microwave cable is minimized;
  4. easy to install: for mounting the device it is necessary to lay only twisted pair, which is much easier, faster, and cheaper, than to lay two microwave coaxial cables;
  5. to power the router does not need to mount a separate cable, as the power is on twisted pair: pair 4-5 serves "+", pair 7-8 serves "-" (the power injector is already included in the delivery set of the device).

Inside the device mini-PCI modem Huawei ME909s-120 is installed.

The router has one LAN port 100 Mbit/s.

System "dish+feed horn" has a very narrow directional diagram (beam angle is 2-3 degrees) so aiming requires precision. Deviation of 1 degree reduces the signal level significantly.

The installation of the feed horn.

Hold down the feed horn in the dish holder. Most operators of 4G-Internet use X-polarization signal. To find out the type of the polarization of the signal from your 4G operator, you need to turn the feed horn in the holder at 45° and view on the indications of the signal level in a program on the computer. In the case of incorrect choice of polarization, the signal level will drop by 30 dB or even more.

Direct the dish to the tower. To do this, the arc from the dish to the irradiator should be directed precisely to the 4G operator's tower. It may seem that the dish is "looking" into the ground. In fact, it receives a signal from the direction of the arc that holds the feed horn. If the tower is far away, the arc will be approximately parallel to the ground.

The dependence of the gain on the diameter of the dish (data are approximate)

The diameter of the dish, meter 0,5 0,6 0,8 0,9 1,2
The coefficient of amplification, dB 23 25 27 29 34

Own antenna gain (without dish) is 8-9 dB.

Note that any obstacles between the tower operator and your dish will lead to a weakening of the signal. It can be trees, houses, buildings, uneven terrain. Therefore, choose the place of installation of the dish so that there was direct visibility of the tower.

The larger the diameter of the applied dishes, the higher the gain. The more the operating frequency, the higher the gain.

ATTENTION! Satellite dish not included!

Attention! The router works with SIM card of any 3G and 4G/LTE operator in the supported frequencies. Warranty - 12 months from the date of sale.
