The KROKS KAA20-1700/2700 BOX MIMO panel antenna is designed for use in conjunction with 3G / 4G modems, in the frequency range 1700-2700 MHz. The antenna is compatible with equipment for the following standards:: 2G (EDGE, GPRS on GSM1800 frequencies) 3G (UMTS 2100) 4G (LTE1800, LTE2600) 2.4 GHz WI-FI (IEEE 802.11 b, g, n) Dimensions (length, width, height), mm 440 x 435 x 105 Package dimensions (length, width, height), mm 445 x 440 x 110 Package weight, grams 3900 Antennas-characteristics : Operating frequency range, MHz 1700-2700 Antenna gain, dB 17-20 SWR in the operating frequency range, max. 1.8 Polarisation ,Linear Wave resistance, Ohms 50 (SMA connector) Maximum input power, W 10 Connector, SMA-female Operating temperature range, oC -40 … +50 Maximum permissible air humidity, % 100 Port decoupling at least, dB 35

,,, and for the 1800MHz frequency... 1800rect-patch.cst

,,,an antenna with square elements cut corners...

,,,for which this antenna must be placed at a height and not have obstacles in front ... !!!!

These are the dimensions for a Yagi antenna with 6 elements and linear dipole CFO-FZo A3 CFO-VZo

,,, this antenna is one of the best, I wonder why it doesn't work for you...!!!!??? ,,,, with 2x2 such antennas I don't think it has a gain of 21dBi but only 18 dBi....

I also need these dimensions ... !!!

,,, try to open the antenna panel, there may be something wrong inside or check the coaxial cable and the connections with the sma plugs...!!! ... could you show the inside of the antenna ... ??? !!!

I have tried many times to make a simulation at this antenna but I was never satisfied with its results. So I made a change to it, and I got some good results, especially with regard to the frequency bandwidth

AGATA-2F 2X2 MIMO Operating frequency range, MHz 1700-2700 Gain, dBi 15.0-18.0 Bottom width (-3dB), deg 16-50 Side lobe level not more than, dB -12 Port decoupling at least, dB 25 Forward / backward ratio, dB 26 Input impedance, Ohms 75 SWR in the operating frequency range at the inputs, max. 1.6 Permissible power, W 10 Polarization of received / emitted waves vertical, horizontal Mechanical characteristics of the antenna Weight with mounting, g 2115 Overall dimensions without mounting, mm 240x450x50 Connectors 2 x F-female Antenna Material, Galvanized steel Material of the protective box, Polycarbonate Dust and moisture ,protection class IP67 Protective coating ,Polymer coating Operating temperature range, -50℃ to +80℃

I don't think this type of adaptation covers a high frequency band with an impedance of 50 Ohm...

Cisco - AIR-ANT2524V4C-R= - 2.4GHz 2dBi/5GHz 4dBi Ceiling Mount Omni Ant., 4-port,RP-TNC Aerial Placing / Mounting:Ceiling mountable, indoor Directivity:Omni-directional Frequency Range:2.4 GHz, 5 GHz Gain:2 dBi (for 2.4 GHz), 4 dBi (for 5 GHz) Voltage Standing Wave Ratio (VSWR):2.0:1 Connector Provided:4 x RP-TNC Cable Length:91.4 cm Depth:2.5 cm Height:18.4 cm Product Type:Antenna Weight:0.59 kg Width:18.4 cm

,,, and impedance .... ??? ,,, why don't you give the dimensions...??? ,, and why not .. ??? batnew.cst ,,,or so..

Batwing antenna and offset dish...

,,, no, this. !!!

,,, put a Batwing antenna in the focus of the parabolic satellite dish ... !!!

,,,for which this antenna variant is also very good ... ???

,,, maybe it would be interesting to see these... https://www.lan23.ru/forum/node/340 https://deracahyono.wordpress.com/2011/02/26/isi-omni-built-up-hyperlink-15-dbi-review/ https://www.lan23.ru/forum/node/462?t=978

I think the best is the galvanized sheet ... !!!

I have only one question,,, for which frequency ... ??
