Proxicast Coaxial Lightning Arrester (ANT-271-002)

The Proxicast ANT-271-002 is designed for TV, satellite, AM/FM, and cable TV/internet setups. It features F-type female connectors compatible with multiple RG cables and can work with 4G/5G signal boosters that use 75-ohm outdoor antennas. It emphasizes bi-directional protection and outdoor-rated construction, making it suitable for inline use in harsh environments.
Key considerations include its 75-ohm impedance and compatibility with common coax standards. The unit’s robust outdoor design helps mitigate surge effects from lightning strikes or strong transients, helping to preserve connected equipment. Installation is straightforward for existing coax runs, and the device offers reliable protection without drastically impacting signal performance.
Proxicast UHF SO-239 Lightning Arrester (ANT-233-002)

This Proxicast model targets VHF/UHF and two-way communications, including amateur/HAM radios and CB applications. It uses two UHF female SO-239 connectors and provides bi-directional protection with outdoor-rated performance. The design emphasizes very low RF insertion loss and a 50-ohm impedance with DC pass-through, preserving signal integrity while offering surge mitigation for critical RF links.
Soft Annealed Ground Wire 10 AWG (25 ft)

Made from copper with a steel core, this 10 AWG ground wire offers enhanced tensile strength for durable grounding runs. Its annealed copper construction allows flexible bending while maintaining conductivity. It is suitable for general lightning protection, electric fencing, and various DIY grounding projects where a reliable, long-lasting conductor is required.
Grounding Cord for Sheets, Mats, 15 ft

This universal grounding cord is designed to replace lost or damaged grounding wires. It is compatible with grounding mats, sheets, pillows, and other earthing products, making it a versatile option for at-home grounding. The 15-foot length supports flexible setup in living spaces while connecting to standard outlets or grounding rods as needed.
Coaxial Grounding / Ground Block Accessories

These accessories address grounding and noise reduction for coaxial runs. They support satellite, broadband, and antenna setups, helping to remove noise and static caused by weather or grounding issues. NEC and local electrical codes often require proper grounding blocks to ensure safe and compliant installations while maintaining signal integrity.
Foboiu Coaxial Lightning Arrester (2 Pack)

Foboiu’s dual-pack offerings provide additional surge protection for HF, VHF, UHF, and CB systems, including HAM and two-way radios. The arrester uses gas discharge tubes and brass-nickel plating for durability in all-weather outdoor environments. It emphasizes wide bandwidth, low insertion loss, and robust interference immunity to protect sensitive equipment and keep signals clear during surges.
Grounding Cord for Sheets (VAJOOCLL)

VAJOOCLL offers a universal 15-foot grounding cord replacement intended for grounding sheets, mats, and other earthing products. It emphasizes compatibility with various grounding accessories and practical use in home settings, enabling a simple upgrade or replacement to maintain grounded readiness.
VQP Grounding Cable Clamp

This aluminum alloy grounding clamp is designed to secure conductors up to 23 mm and includes a coiled 16.4-foot anti-static wire. It includes three copper nails for robust three-point contact, improving grounding reliability in industrial environments such as fuel depots, chemical plants, or garages where static control is critical.
Buying Guide: Key Considerations For Grounding Cables And Lightning Protection
- Impedance and compatibility: Look for 50-ohm or 75-ohm ratings depending on your coaxial system and ensure compatibility with common connectors (F-type, SO-239, etc.).
- Outdoor durability: For lightning and surge protection, choose outdoor-rated materials with corrosion resistance, weather sealing, and robust connector hardware.
- Signal integrity: Choose arrester designs that minimize RF insertion loss and DC pass-through when needed, so protective measures don’t degrade performance of your RF links.
- Connector versatility: If you operate multiple systems (TV, satellite, HAM radios), select products offering compatible interfaces across the common connector types used in those setups.
- Installation flexibility: Consider cable length options (short runs for dense installations or longer runs for remote equipment) and whether a grounding cord can connect mats, sheets, or rods as required by your setup.
- Code compliance: Ensure devices meet NEC or local electrical codes for grounding, grounding blocks, and surge protection to avoid compliance issues during inspections.
- Maintenance and replacement: Grounding components should be inspectable, replaceable, and resistant to wear from outdoor exposure and UV light to maintain long-term protection.
- Use-case diversity: For corporate or large home networks, a mix of uplink protection, RF attenuators, and grounded coax accessories can protect both signal paths and equipment shelves.
In summary, the best grounding cable solution depends on your specific configuration—antenna systems, coax runs, and the level of surge protection you require. The models listed here balance durability, compatibility, and grounding reliability to help maintain system integrity during lightning events and electrical transients.
