Faraday Fabric 43″ x 118″
ARCTIC EAGLE’s Faraday Fabric uses a multi-layer copper structure to deliver robust shielding across 10 MHz to 20 GHz. With a 0.09 mm thickness and a 70 dB attenuation target, it provides strong EMF reduction for generator protection, networks, and wireless devices. The fabric is designed with a nickel-copper-nickel alloy to improve durability and corrosion resistance, prolonging the shield’s life. Available in multiple 43″ widths and lengths, it accommodates a range of generator and equipment setups, from compact to expansive shielding zones.
Dry Shield Rapture Faraday Bag 1,060L
Mission Darkness offers a military-grade Faraday bag with an impressive 1,060-liter capacity, designed to fit portable gas or solar generators and oversized electronics. Three layers of high-shielding TitanRF fabric line the interior, and the bag employs dual paired seams to maintain shielding integrity during EMP or CME events. It blocks WiFi, Bluetooth, GPS, RFID, and other RF signals with about 70 dB attenuation, enabling robust protection for emergency gear and power systems in field and home environments.
Dry Shield Revelation EMP Armor
Revelation EMP Armor is a MIL-STD-188-125-certified Faraday bag designed for generators and large electronics. The bag provides extra-large usable dimensions (approx. 30″ x 24″ x 22″) with portable folds for storage, making it suitable for mobile prep kits and home use. Its construction focuses on preserving device functionality amid EMP and CME events while remaining user-friendly for quick deployment and seal integrity through rugged environments.
G CUBƎ 100 Faraday Bag
Designed to shield portable power stations and generators, the G CUBƎ 100 by Xtreme Sight Line emphasizes a compact roll-top with a 20″ x 20″ footprint and 15″ depth in shielded configuration. Made in the U.S.A., it targets EMI, EMP, and GMD threats while providing a protective interior for sensitive electronics. The rugged exterior and internal Faraday lining combine to deliver dependable defense against RF interference in disaster readiness or field operations.
TitanRF DIY Faraday Cage Kit
The TitanRF DIY Faraday Cage Kit is an all-inclusive solution for building a custom cage liner inside a standard tote. It includes TitanRF Faraday Fabric, tape, anchors, jig, clamps, gloves, and an instruction guide. The kit is MIL STD 188-125 and IEEE 299-2006 certified, ensuring protection for generators, laptops, radios, and other critical devices. It is ideal for users who want a tailored shield for specific dimensions and logistical needs, with clear assembly steps for optimum performance.
Buying Guide: Key Purchase Considerations
- Application scale: For generators and large electronics, prioritize products with high shielding (70 dB or more) and large interior dimensions to accommodate bulky items.
- Shielding material: Multi-layer copper or TitanRF fabric offers strong frequency coverage and durable construction. Assess seal integrity and seam construction for EMP resilience.
- Portability vs. permanence: Bags and sleeves provide rapid deployment and transport, while DIY kits enable customized fits for fixed setups.
- Certified performance: MIL-STD and IEEE certifications indicate tested reliability under EMP/CME conditions; look for reports or documentation when available.
- Durability and environment: Fireproof, waterproof, and corrosion-resistant materials extend the shield’s lifespan in various conditions, from basements to outdoor shelters.
- Size options: Ensure the chosen product offers dimensions compatible with the generator size and other equipment you plan to shield.
- Ease of use: Consider the time required to deploy, seal, and retrieve items, especially for emergency scenarios where quick protection is essential.
- Maintenance: Reusability of shielding fabrics and the integrity of bags under repeated use are important for long-term setups.
