CT-12H is a super-powerful portable jammer that combines the power of large stationary signal blockers with portability. It effectively blocks all mobile, GPS, and WiFi signals across 12 frequency bands, ensuring total signal silence where it's needed most. The CT-12H sets a new benchmark in portable jamming. Outclassing older models like the PJ-12S, P12H, PJ-12, PJ-122, PJ-121 and even the New P-12Ultra High power phone Jammer, it delivers performance on par with our best-selling Powerful desktop Jamming device DJ-122—while maintaining full mobility.
Our engineers have upgraded the CT-12H to block LoJack signal in addition to standard tracking frequencies, effectively countering almost all types of unwanted trackers.
This enhancement makes the jammer far more versatile and truly multi-functional — one device serving multiple purposes.
