Network antenna accessory ALLNET MC-6BP

The ALLNET MC-6BP (AL6-NMNFBW-9) is a compact gas discharge tube lightning and RF protector with bulkhead N-female connectors and an O-ring seal for through-wall mounting. It provides wide-band protection and reliable performance from DC up to approximately 6 GHz while allowing DC to pass through the coax, making it suitable for systems that require remote power or inline DC to active components.

Advantages

This protector offers bi-directional protection with both connector ports equally protected, a replaceable gas tube element and multi-strike capability for extended service life. Its high-quality construction includes a durable brass housing and a ground lug/terminal on the housing for straightforward grounding. The unit’s RF performance supports high-frequency applications up to 6 GHz and preserves signal integrity for sensitive equipment.

Suitable for

• IEEE 802.11a and 5.2–5.8 GHz ISM/UNII wireless links
• 3.5 GHz WLL (wireless local loop) systems
• Installations requiring DC pass-through to remote amplifiers or LNAs
• Outdoor or through-panel antenna feedthroughs on enclosures

Key specifications

• Model: ALLNET MC-6BP (AL6-NMNFBW-9)
• Connector: bulkhead N-female to N-female
• Frequency range: DC to ~6 GHz
• Construction: brass housing, rubber O-ring seal
• Features: replaceable gas tube element, bi-directional protection, multi-strike capability
• Dimensions (from product data): 68 mm × 23 mm × 31 mm
• Sold as: single unit

How to use

Mount the protector through the enclosure wall or use the optional stainless-steel mounting bracket; ensure the O-ring provides a proper seal when installed through a panel. Connect the antenna cable to one N-female port and the equipment feed to the opposite port. Verify the ground lug on the housing is securely connected to the site ground to ensure effective surge diversion. Because the device passes DC, it can remain inline when DC power is supplied over the coax to remote amplifiers or LNAs.

Recommendations

For reliable protection, install the unit with a low-impedance ground connection and periodically inspect the replaceable gas tube element after significant lightning activity or multiple surge events. Replace the gas tube element per manufacturer guidance if degradation is observed.
