Description

The KAA20-1700/2700 is a wideband directional panel MIMO antenna produced by KROKS Plus LLC, a scientific-production company based in Voronezh that has been designing and manufacturing wireless communication equipment for the Russian market for many years. Covering the full 1700–2700 MHz band, the antenna delivers a gain of 17–20 dBi, making it highly effective for boosting 3G and 4G connectivity at considerable distances from cellular base stations.

The dual-port MIMO 2×2 design enables LTE cat.4 modems to reach speeds up to 150 Mbit/s and LTE cat.6 modems up to 300 Mbit/s. Compatible standards include GSM 1800, UMTS 2100, LTE 1800/2100/2300/2600, and Wi-Fi 2.4 GHz (IEEE 802.11b/g/n).

The sealed ABS plastic housing is UV-resistant and weather-tight, rated for operation from −40 °C to +90 °C at up to 100% relative humidity, enabling year-round outdoor installation without additional protection. Antenna inputs are DC-shorted between inner and outer conductors, which dissipates static charge and reduces the risk of damage to connected modems or routers — eliminating the need for a separate lightning arrester in most installations.

Port-to-port isolation is at least 30 dB. The mounting bracket accommodates pipes 32–40 mm in diameter and supports full azimuth, tilt, and polarization adjustment for precise signal alignment.

Details & Equipment

Antenna Views

Front panel

The 430 × 430 mm panel face with its flat radiating array provides the 17–20 dBi directional gain across the 1700–2700 MHz band.

Connector detail

Both N-female and F-female output connectors are accessible on the housing, offering compatibility with a wide range of coaxial assemblies and modem pigtails.

Mounting bracket

The rear bracket clamps to masts 32–40 mm in diameter and includes hardware for setting azimuth, tilt angle, and polarization orientation.

RF Performance Diagrams

Vertical radiation patterns

Measured elevation-plane radiation patterns across 1800–2700 MHz confirm a narrow vertical beamwidth consistent with the 20 dBi gain specification.

Horizontal radiation patterns

Azimuth-plane patterns across 1800–2700 MHz show a well-defined main lobe with good front-to-back ratio, as expected from a high-gain panel design.

VSWR across operating band

The measured VSWR curve stays at or below 2 throughout the 1700–2700 MHz range, confirming good impedance match and low reflected power on both ports.

Features

📡

17–20 dBi Gain

Delivers 17–20 dBi of gain across the full 1700–2700 MHz band, enabling reliable LTE and 3G connections even at the outer edge of a base station's coverage zone.

🔄

MIMO 2×2 Dual Port

Two spatially separated feed ports with at least 30 dB of inter-port isolation allow simultaneous use of both LTE spatial streams, supporting data rates up to 300 Mbit/s with cat.6 modems.

🌦️

All-Weather ABS Housing

Hermetically sealed UV-resistant ABS plastic enclosure operates from −40 °C to +90 °C at 100% relative humidity and withstands wind loads up to 30 m/s.

⚡

Built-In Static Protection

DC short-circuit between inner and outer conductors on each port prevents static charge accumulation, protecting connected modems and routers without requiring a dedicated lightning arrester.

📶

Multi-Standard Coverage

A single antenna covers GSM 1800, UMTS 2100, LTE 1800/2100/2300/2600, and Wi-Fi 2.4 GHz (IEEE 802.11b/g/n), allowing automatic fall-back from 4G to 3G when needed.

🔧

Adjustable Mounting Bracket

Included bracket fits masts 32–40 mm in diameter and allows adjustment of azimuth, vertical tilt, and polarization to maximise signal toward any base station orientation.

Buyer Benefits

Achieves LTE data rates up to 300 Mbit/s (cat.6) or 150 Mbit/s (cat.4) when used with a MIMO-capable modem or router
Covers all mainstream Russian cellular and Wi-Fi bands in one unit, removing the cost and complexity of separate per-band antennas
20 dBi peak gain extends usable LTE range far beyond what compact or omnidirectional antennas can provide
Built-in DC shorting eliminates most static-induced modem failures, reducing downtime and replacement costs
Sealed housing and wide temperature range mean no seasonal maintenance or weatherproofing is required
Azimuth and tilt adjustability lets installers fine-tune signal capture at any mounting height and orientation
N-female and F-female connector options suit a wide variety of modems, routers, and coaxial cable assemblies

Applications

Rural and suburban homes and offices where LTE signal is weak or inconsistent Fixed wireless broadband setups requiring stable high-throughput 4G connectivity Industrial facilities, warehouses, and manufacturing sites needing reliable mobile data coverage Remote monitoring, telemetry, and SCADA systems with marginal cellular signal M2M and IoT gateway installations in hard-to-reach or cell-edge locations Outdoor Wi-Fi 2.4 GHz links supplemented by cellular backup on the same antenna Construction site offices and temporary field camps where wired internet is unavailable Vehicle-mounted or portable communication kits requiring a high-gain directional panel
