Description
Coaxial Cable Grounding Kit for 1/2" Corrugated RF Transmission Lines
Genuine Motorola Solutions infrastructure grounding kit sourced from Fiplex Communications Inc (Supplier Item #: BDA-GNDKIT1) featuring 16 mm² copper lead and M8 lug.
The Motorola DSBDAGNDKIT1 (supplied directly by Fiplex Communications Inc under Supplier Item #: BDA-GNDKIT1) is a commercial-grade coaxial cable grounding kit engineered to safeguard critical Land Mobile Radio (LMR), Bi-Directional Amplifier (BDA), and Emergency Radio Communication Enhancement Systems (ERCES). Sourced directly from our verified inventory of Two-Way Radio Antennas, this kit provides a direct, low-impedance electrical bond from the outer copper shield of 1/2-inch corrugated coaxial cables directly to the facility or tower grounding system, neutralizing lightning strikes and power surges before they can reach sensitive active RF equipment.
Manufactured with high-grade components for harsh indoor and outdoor installations, the Motorola DSBDAGNDKIT1 utilizes a corrosion-resistant stainless steel clamping band engineered to conform smoothly around 1/2-inch corrugated copper coaxial cable (such as HELIAX and Cellflex) without damaging the internal dielectric core. The pre-attached 500 mm (19.7-inch) bonding conductor is made of heavy-duty 16 mm² copper wire insulated in an outdoor UV-resistant black PVC jacket and terminated with a factory-crimped, tin-plated copper lug with an M8 (5/16-inch) mounting hole. Tested to meet electrical grounding benchmarks under UL Standards (UL 467) and transient protection guidelines under IEEE Standards (IEEE C62.41), this assembly satisfies NFPA 1221, NFPA 1225, and International Fire Code (IFC) mandates for public safety in-building BDA systems. To comply with environmental protection benchmarks under IEC Standards (IEC 60529 IP68) and workplace safety protocols under OSHA Standards, the kit includes commercial butyl mastic sealant and heavy-duty vinyl tape to provide a weather-tight seal that locks out driving rain, ice, and atmospheric moisture.

Frequently Asked Questions
What is the relationship between Motorola DSBDAGNDKIT1 and Fiplex BDA-GNDKIT1?
The Motorola catalog number DSBDAGNDKIT1 represents the official distribution package manufactured by Fiplex Communications Inc under Supplier Item #: BDA-GNDKIT1. Both part numbers refer to the exact same commercial-grade 1/2-inch coaxial grounding assembly designed for public safety in-building bi-directional amplifier systems.
Where along the coaxial cable run should this grounding kit be installed?
Industry standards (including NFPA 1221/1225 and Motorola R56 site standards) recommend installing grounding kits at three primary locations: near the antenna connection at the top of the tower or roof, at the bottom of the vertical cable run prior to horizontal routing, and immediately outside the building entrance hatch plate before the cable enters the equipment shelter.
What size coaxial cable does this kit support?
The DSBDAGNDKIT1 is engineered specifically for 1/2-inch corrugated copper coaxial cable (including standard corrugated cables such as CommScope HELIAX LDF4-50A, superflexible FSJ4-50B, AVA4-50, and equivalent RFS Cellflex lines). It is not intended for smaller braided cables such as RG-58 or LMR-400.
Does this kit include weatherproofing materials?
Yes. The kit includes industrial-grade butyl mastic sealant tape and heavy-duty vinyl electrical tape. Applying the mastic sealant directly over the clamp area followed by overlapping vinyl tape seals the stripped coaxial jacket against moisture ingress to achieve an IP68 waterproof rating.
What size bolt does the terminal lug accommodate?
The grounding conductor is pre-terminated with a tin-plated copper lug featuring an M8 (5/16-inch) hole, allowing secure fastening to standard master ground busbars (MGB) using 5/16-inch or M8 stainless steel hardware.
