P-FM1 Portable FM Radio Jammer, equipped with a 360° Omnidirectional Rotating Antenna (50M)

FM broadcast coverage in the 80–108MHz range is where this Single-antenna FM radio jammer operates. A stable 5W RF output sits at the center of its signal handling behavior, pushing interference outward in a controlled and continuous pattern. In open environments, the effective radius can extend up to 50 meters, although surrounding density and receiver sensitivity will always influence the final result.

A 360° rotatable omnidirectional antenna distributes output evenly in all directions, and the rotation adds another layer of flexibility to positioning.

No directional alignment is required, yet coverage remains uniform regardless of how the unit is placed.Considering how most compact RF devices struggle with maintaining balance at different angles, this structure holds a more stable field pattern in practical use rather than relying on fixed orientation.

Power flexibility is another key point. The system supports AC input, vehicle charging, and a built-in 7.4V 3000mAh lithium battery. In real usage, this means operation does not depend on a fixed environment. You can switch between stationary and mobile setups without modifying the device.

Controls are kept minimal: a physical power switch, a working indicator, and a charging indicator. You can also see a series of small perforated holes along the side of the unit—yes, this is its heat dissipation system. Nothing unnecessary is added, yet everything essential is visible at a glance.

Notice:

• If hissing sounds persist after turning off the jamming device, you will need to manually restart the device. The signal will automatically recover when using an analog radio. Due to the suppressor's high power, some radio models may be damaged if placed too close to it. It is recommended to test with an older or low cost radio first.
• This product is custom-made; each device is assembled to order. The delivery time is approximately 10-15 days. Thank you for your understanding.
