MAIN FUNCTIONS:
Trench device “Greek 4M” – is an electronic warfare tool for countering FPV drones
operating in the frequency range (470-530 MHz or 410-490 MHz.) 700-1050 MHz, 

It has four separate jamming bands:
(470-530 or 410-490).
700-820 MHz.
800-920 MHz.
900-1050 MHz.
and has the ability to jam all bands simultaneously and will block communication for the most popular FPV transmitters.

EW GREEK 4M – is a reliable and powerful tool for protection against electronic interference.
Combining numerous functions, a wide range of operating frequencies, and compact dimensions, it is an indispensable component in the security system.

A significant advantage of the model will be its weight of 7 kg and dimensions of 370x295x134 mm for comfortable transportation or storage.

The model also has a wide operating temperature range from -30°C to +50°C.
Special attention has been paid to the casing – it is made of heat-dissipating materials with a cooling system to avoid overheating.
The level of moisture protection and dirt protection IP 54 will prevent dust and moisture from entering the casing.

Thanks to its characteristics and advantages, EW GREEK 4M will become an indispensable tool for ensuring the safety of military facilities, infrastructure, and people.

Operation from 220V = 158,000 UAH (with quadrifilar antennas)
Operation from 220V = 151,000 UAH (with collinear antennas)

TECHNICAL SPECIFICATIONS:

THE GREEK 4M INCLUDES:

OPTIONALLY, THE FOLLOWING CAN BE ADDED:

HOW ANTENNAS OF DIFFERENT TYPES WORK

Collinear antennas – on a moving object (fig. A). The drone enters the action zone of the EW device while moving, unable to fly over the moving unit. They provide a greater distance of interference spread. 

Dome-type antennas – on stationary positions (fig. B). They have coverage ABOVE the protected object at a better level, but have a smaller radius of action.

PRODUCT DESCRIPTION:

Power Supply:
The device operates on 220 V and optionally 28 V, with separate inputs for them.
The 220 V connection socket IEC 60320 / C7 (figure eight), a cable is included.
The 28 V connection socket TX60 (yellow) – optional. When ordering – MANDATORY consultation on usage.

Control Elements 
They consist of buttons on the casing for powering on and activating each jamming band separately/or together.

1. The “Power” button – turns the power on/off.
   The lower position – turns on the device, if the “Power” button indicator is lit in color – power is supplied to the device and it is ready for use.
   The upper position – turns off the device, the button indicator does not light up.
2. The “1” button – turns the first jamming band 700-820 MHz on/off.
   The lower position – turns on the first jamming band 700-820 MHz, if the “1” button indicator is lit in color – the first jamming band is active.
   The upper position – turns off, the button indicator does not light up. 
3. The “2” button – turns the first jamming band 800-920 MHz on/off.
   The lower position – turns on the first jamming band 800-920 MHz, if the “2” button indicator is lit in color – the first jamming band is active.
   The upper position – turns off, the button indicator does not light up.
4. The “3” button – turns the second jamming band 900-1050 MHz on/off.
   The lower position – turns on the first jamming band 900-1050 MHz, if the “3” button indicator is lit in color – the second jamming band is active.
   The upper position – turns off, the button indicator does not light up.
5. The “4” button – turns the third jamming band 470-530 MHz on/off.
   The lower position – turns on the first jamming band 470-530 MHz, if the “4” button indicator is lit in color – the third jamming band is active.
   The upper position – turns off, the button indicator does not light up. 
6. The LED button for turning on/off the illumination of the jamming band buttons

On standard models, pressing the buttons is accompanied by light indication, but on some versions it may be absent.

INSTALLATION REQUIREMENTS:

Connection to an external power source, 220 V or 28 V (optional).
Absence of physical damage to the device, antennas, and power supply cable 
Properly connected corresponding antennas.
Antennas of the device are positioned vertically. Ambient temperature not lower than -30°C and not higher than +50°C.

ADVANTAGES OF OUR EW DEVICES:

• Affordable price
• We cover the bands requested by the military, not those that were relevant six months ago
• Combined solution: for vehicle and trench EW due to special springs and antennas
• We conduct selection of antenna equipment (to use optimal antennas to ensure the safety of various positions)
• We strive for the organization of real dome protection
• We conduct thorough diagnostics of the equipment before shipment
