Portable EW is a compact wearable anti-drone tool for those who work without a vehicle: a trench, an observation post, an assault. In short: you switch it on the moment a threat appears, and it jams drone control at close range.
Here you'll find handheld stations and «Patelnia» anti-drone guns (KANT-M-3, KANT-M-4). Below is when each format is more convenient.
Who needs a trench jammer
Portable EW is for infantry, assault teams, crews and observers — anyone without a vehicle-mounted complex on hand.
Its main advantage is that you can always take it with you. Handheld EW is carried in a backpack or kept ready and activated when a drone is heard. It is personal protection from FPV and drops, not a stationary solution.
The «Patelnia» anti-drone gun
«Patelnia» is a handheld directional EW in a "gun" form factor. You aim it toward the drone and cut its control and video channels.
Models:
- KANT-M-4 «Patelnia» — infantry handheld EW on 2.4 / 5.2 / 5.8 GHz, drop protection from DJI Mavic 3 and 4.
- KANT-M-3 «Patelnia» — a more compact version on 2.4 and 5.8 GHz.
The directional form is good because it concentrates power toward the drone instead of radiating in all directions.
Protection from Mavic drops
A distinct job of infantry EW is drop protection. A Mavic drone moves over a position and releases a munition; the handheld EW cuts its 2.4/5.8 GHz channels, breaking the aim and control.
That's why «Patelnia» works on Mavic's Wi-Fi frequencies — it is the main drop carrier in the front-line zone.
Portable or vehicle EW
Simple selection logic:
- No vehicle, need personal protection → handheld infantry EW.
- Cover gear on the move → vehicle dome EW.
Buyers often take both: the vehicle complex covers transport, and «Patelnia» stays with the soldier on the position.
Frequencies and effectiveness
Handheld EW works on 2.4 / 5.2 / 5.8 GHz — the bands of Mavic and much of FPV. At close range a directional device effectively breaks control.
For harder scenarios (low-band FPV), wider-band solutions are needed — then look toward multi-band complexes or combine tools.
Kit and power
Portable EW runs on a built-in battery charged from a socket or a power bank. The device is built for the field — dust, moisture, shocks.
Every unit is tested before shipping. If you need to complete the system with antennas or cable, that's in the antennas & accessories section.
Tactics for using handheld EW
Portable EW is effective only when it's used in time. So the main rule is to keep the device ready and switch it on at the first signs of a drone: sound, visual contact, a spotter's warning.
The directional «Patelnia» is aimed toward the aircraft — that way all the power goes into the needed sector instead of scattering. At close range this breaks control and forces the drone to lose the target or pull away.
Don't radiate continuously without need: it drains the battery and gives away the position. Handheld EW is a "button for when a threat appears", not background cover. For a constant perimeter, a vehicle dome complex makes more sense.
Battery, weight and readiness
Autonomy is the key parameter of portable EW. The device runs on a built-in battery charged from a socket or a power bank, so for long watches it's worth having a spare source.
The format is made for carrying: the station goes in a backpack, the gun stays at hand. Check the exact weight and runtime on the specific model's page — they differ between KANT-M-3 and KANT-M-4.
Before heading out, check the charge and function — the same way a weapon is checked. A device sitting there discharged won't save you from a drone.
Questions & answers
What is a trench jammer?
It is a compact wearable EW device for positions. It creates radio interference and jams a drone at close range when no vehicle complex is nearby.
How much does a handheld EW cost?
Price depends on the model and band set. Compact versions are cheaper than multi-band ones. See the current price on the «Patelnia» page or ask a manager.
Does an anti-drone gun protect against drops?
Yes. «Patelnia» covers Mavic 2.4/5.8 GHz channels, so it breaks drone control during a drop run.
What frequencies does infantry EW use?
2.4 / 5.2 / 5.8 GHz — the bands of Mavic and most FPV. Low-band aircraft need wider solutions.
Is handheld EW heavy? Is it carried in a backpack?
The format is built for carrying: the station goes in a backpack, the «Patelnia» gun is kept ready. Check the exact weight on the model's page.
