Import Cell Phone Jammers — Buy in Bulk from Supplier in China

The SK-01F Remote Control Wireless Phone Jammer is a portable signal disruption device designed to block cellular communications across CDMA, GSM, DCS, and 3G frequency bands. It operates with adjustable output power to control the effective jamming radius, typically up to 3 meters in open environments, and features a 360-degree swivel antenna for directional coverage. The unit measures 29.5 by 15 by 11 centimeters and weighs 1.5 kilograms, with dual power options: internal battery or mains adapter.

This jammer uses high-frequency interference technology to disrupt downlink signals only, avoiding interference with base station transmissions. It does not transmit or receive any signals itself, ensuring compliance with non-interception standards. The device is engineered to function in environments with varying signal strengths, where proximity to cell towers or physical obstructions can influence its effective range. No certification claims are provided by the supplier regarding regulatory compliance or EMC standards.

The device is used by law enforcement, military units, and institutions such as museums, theaters, classrooms, and banks to prevent unauthorized communication in secure or quiet zones. Buyers typically require it for controlled environments where mobile phone use must be restricted. Trade terms are not specified; buyers must confirm minimum order quantities, packaging, and delivery conditions directly with the supplier. The product is shipped from Beijing, China.
