Desktop UHF/VHF Walkie-Talkie-Jammer Blocks 315/433/868MHz/Lojack Signals (18W)

What makes stationary blocking equipment stand out is not just the 18W output, but the way it handles a surprisingly wide spectrum: UHF, UKW (FM), LoJack, 315MHz, 433MHz, and 868MHz. And here’s the interesting part—this range also includes VHF and UHF frequencies commonly used in walkie-talkies and alarm systems.

This FM radio signal blocker uses an integrated extruded aluminum alloy base, with vertical heat-dissipation fins. A side-mounted axial fan further enhances airflow, forming an end-face air intake/through air duct to quickly remove internal heat along the fin direction.

This 315 433mhz car remote control jammer abandons complicated menus and cumbersome digital operations, allowing for easy adjustment of antenna output at any time with just a rotating knob, which is refreshing.

To meet different interference suppression requirements, our engineers have developed the following frequency combinations:

• Combination A: UHF, VHF, Lojack, 315MHz, 433MHz, 868MHz
• Combination B: GSM, PCS, 3G, 4G (LTE/WiMAX), WiFi 2.4G / Bluetooth
• Combination C: GSM, PCS, 3G, 4G (LTE/WiMAX), GPS L1
• Combination D: Selectable frequency bands (no more than six)
