Proxicast Coaxial Lightning Arrester with 2x UHF SO-239 Connectors – Outdoor RF Surge Protector for Ham, CB & VHF/UHF Radios

Overview

The Proxicast ANT-233-002 Coaxial Lightning Arrester/Suppressor is a rugged, outdoor-ready surge protector designed to safeguard RF antenna setups. Featuring two UHF female SO-239 connectors, it installs inline on coax runs for VHF, UHF, amateur/HAM, and CB radios. Its robust, weather-resistant housing is built for field deployments or fixed installations, helping you maintain reliable signal paths in challenging environments.

Designed to blend protection with performance, this unit sits between the antenna feedline and ground. Its compact form is ready for mast or cabinet mounting, offering a neat, protection-focused upgrade to existing systems without adding unnecessary bulk to the signal path.

Key benefits and how it helps

• Bi-directional protection keeps the feedline safe while allowing normal signal flow in inline installations.
• Very low RF insertion loss with a 50 ohm impedance and DC pass-through maintain signal quality across the path.
• 230V gas discharge tube delivers multi-strike surge protection by shunting transient energy to ground, potentially reducing stress on connected gear.

• Outdoor-rated design built to withstand exposure on towers, rooftops, or exterior rigs.
• Two UHF female SO-239 connectors support flexible antenna configurations and easy inline integration.
• Grounding-friendly installation connects your feedline to earth ground for a clean protection path.

Designed for real-world setups

Whether you operate VOIP-free field days, home stations, or temporary event antennas, this protector helps you preserve signal integrity while adding a shield against surges and transients. The unit’s bi-directional stance means it can adapt to diverse coax runs and two-way radio configurations without forcing complex rewiring. While outcomes depend on your specific system and conditions, the ANT-233-002 offers a practical upgrade path for enhanced resilience and peace of mind.
