Icom 691-002-1491 6910021491 Antenna connector for Radios F3001 / F4001

The Icom 691-002-1491 is an OEM replacement antenna connector intended for use with the F3001 and F4001 series portable two-way radios. Over the service life of a professional radio, the antenna connector is one of the most mechanically stressed points on the device — subjected to repeated antenna changes, accidental pulls, and general field wear. When this interface degrades, signal performance and overall radio reliability suffer, making timely connector replacement a critical element of any serious maintenance program. This genuine Icom part restores the radio's antenna interface to its original design standard, ensuring the mechanical and electrical relationship between the antenna and radio body is maintained as the manufacturer intended. It is suited for use by qualified radio technicians, fleet maintenance teams, and professional repair depots that service Icom portable radios and require factory-grade replacement components rather than generic alternatives.

Key features & benefits

• OEM-Grade Replacement — Sourced directly from Icom, this connector meets the original design and construction standards established for the F3001 and F4001 radios, supporting consistent, predictable repair outcomes.
• Targeted Compatibility — Engineered specifically for the F3001 and F4001 portable radio platforms, eliminating the guesswork and fitment risk associated with generic or third-party connector substitutes.
• Critical Wear-Point Restoration — The antenna connector is among the highest-wear mechanical interfaces on a portable radio. Replacing a damaged or worn connector restores the integrity of this junction and supports continued reliable operation.
• Professional Maintenance Application — Designed for bench-level repair and depot maintenance workflows, this component supports technicians performing component-level service rather than full-unit replacement.
• Preserves Radio Investment — By enabling precise, manufacturer-aligned repairs, this connector helps extend the operational lifespan of existing radio inventory, reducing total cost of ownership for fleet operators and institutions.
