SZ Vodasafe N18 The Ultimate 18-Band Handheld 5G Signal JammerIn an era where seamless connectivity coexists with the critical need for silence, confidentiality, and information security, SZ Vodasafe proudly presents the N18 Handheld 18-Band 5G Cellphone Signal Jammer---a cutting-edge solution designed to block unwanted wireless signals across a wide spectrum. Crafted with precision engineering and user-centric features, the N18 redefines signal jamming technology, making it an indispensable tool for diverse professional and public environments.The SZ Vodasafe N18 is a portable, all-in-one signal jammer encased in a durable ABS shell, integrating 16 high-performance omni antennas (with dual-band design for key channels) to target and block 18 distinct signal bands. It effectively neutralizes signals from 2G, 3G, 4G, and 5G mobile networks, as well as Wi-Fi (2.4G/5.2G/5.8G), GPS (L1-L5), UHF/VHF walkie-talkies, LOJACK tracking signals, and RF frequencies (315MHz, 433MHz, etc.).With a compact form factor (210x130x46mm without antennas) and a weight of approximately 2.0kg (gross weight), the N18 balances portability with power---delivering a total output power of 18W (1W per band) and a jamming radius of 2-20 meters (at -75dBm, subject to ambient signal strength). Its sleek black design and intuitive LCD display make it both functional and user-friendly, suitable for long-term use in various settings.

Signal BandsThe N18 is available in two region-specific models to adapt to global frequency standards: N18-EU (optimized for the European market) and N18-US (tailored for the U.S. market). Below is a detailed breakdown of their targeted signal bands, output ports, and frequency ranges:N18-EU (European Standard)

Specifications
Features
All-in-One Signal BlockingThe N18 covers nearly all common wireless signals, including:Mobile networks: 2G, 3G, 4G, 5G (compatible with Android, iOS, Windows phones, tablets)Wireless internet: Wi-Fi 2.4G, Wi-Fi 5.2G, Wi-Fi 5.8GPositioning & tracking: GPS (L1-L5), LOJACKShort-range RF: UHF, VHF (walkie-talkies), RC315, RC433, 868MHzSpecialized bands: CDMA450MHz, LORAFlexible Band ControlEquipped with a DIP switch on the side, users can independently turn on/off any of the 18 bands without affecting others. This allows for precise signal management-ideal for scenarios where only specific signals need to be blocked (e.g., disabling Wi-Fi jamming while keeping mobile network blocking active).Reliable Cooling & DurabilityDual cooling protection: A high-efficiency aluminum alloy radiator and 3 built-in cooling fans prevent overheating, ensuring stable operation even during prolonged use.Durable build: The ABS shell resists impact and scratches, while the nylon handheld cover enhances grip and comfort. The device operates safely within a temperature range of 45-60°C; if temperatures exceed this threshold, it is recommended to power off immediately to avoid damage.User-Friendly DesignEasy installation: Antennas are pre-connected and labeled with numbers-simply attach them to the corresponding ports and tighten.Intuitive LCD display: Real-time monitoring of battery life (percentage), working voltage, and current helps users stay informed about the device's status.Dual charging options: Use the AC adapter for indoor charging or the car charger for on-the-go power, making it suitable for mobile scenarios like trains or buses.
Application ScenariosThe SZ Vodasafe N18 is designed for environments requiring silence, confidentiality, or information security. It is widely applicable in:Professional spaces: Meeting rooms, conference halls, training centers, banks, factories (to prevent information leaks or distractions).Public venues: Museums, galleries, theaters, concert halls, churches, temples, restaurants (to maintain a quiet atmosphere).Transportation: Trains, buses (to avoid disruptions from loud calls or video playback).Important Notes for Special EnvironmentsFor locations with critical equipment (e.g., hospitals, gas stations), field testing is mandatory before use to ensure no interference with the normal operation of medical devices, fuel pumps, or other sensitive systems.Installation & Usage GuideFirst-Time SetupCharge the battery: Before initial use, charge the built-in battery for at least 8 hours. Turn off the power switch before charging-the charging indicator will glow red and turn green once fully charged.Install antennas: Attach the 16 omni antennas to the corresponding numbered ports (labeled 1-18) and tighten them securely. Do not power on the device if antennas are not connected-this may damage internal components.Power on: Flip the power switch; the power LED will turn green, and the LED for each active band will also illuminate (default: all bands are on).Band Control (DIP Switch)Locate the DIP switch on the side of the device (labeled CH1-CH18).By default, all switches are set to "ON" (all bands active). To disable a band, toggle the corresponding switch to "OFF"-the band's LED will turn off to confirm.To reactivate a band, toggle the switch back to "ON".Usage TipsOptimal placement: For maximum jamming coverage, place the device at a height of ~2 meters (e.g., on a shelf or stand) to avoid obstructions.Avoid interference: Keep the N18 away from computers, laptops, televisions, radios, or audio equipment to prevent signal interference with these devices.Battery maintenance: The Ni-MH rechargeable battery supports approximately 500 charge cycles. If the battery no longer holds a charge, contact your local SZ Vodasafe agent for replacement.Package ContentsEach SZ Vodasafe N18 package includes:1 x N18 Signal Jammer Host1 x AC Power Adapter (110-240V AC to 12V DC)1 x DC 12V Car Charger16 x Omni Antennas (with dual-band design for CH12/13 & CH15/16)Warranty & SupportSZ Vodasafe stands behind the quality of the N18 with a 1-year warranty from the date of delivery.
