Description
VHF (144-174 MHz) Mobile Antenna with Spring
High-Gain NMO Solution and 100% Replacement for Icom Antenna 2
The TE Connectivity B1443S is an industrial-grade, 5/8 wave base-loaded mobile antenna designed for high-performance communication across the 144-174 MHz VHF spectrum. Measuring 49 inches in length, this omnidirectional whip antenna features a precision-machined chrome base coil and a heavy-duty stainless steel spring. The integrated spring provides critical flexibility, allowing the antenna to deflect upon impact with low-hanging obstructions, which prevents damage to the vehicle's mounting surface and ensures long-term operational reliability for public safety, utility, and transportation fleets.
Engineered as a primary alternative for discontinued infrastructure, the TE Connectivity B1443S is 100% compatible with the legacy Icom Antenna 2 (now EOL). By utilizing the TE Connectivity B1443S, fleet managers can maintain their existing Icom mobile radio systems with a drop-in replacement that meets or exceeds the original's electrical specifications. With a 3 dBi gain and a standard NMO mount, this antenna delivers the extended range and consistent 360-degree coverage required for mission-critical VHF voice and data transmissions.
Key Features & Benefits
-
Drop-In Replacement for Icom Antenna 2: Specifically vetted to replace the End-of-Life (EOL) Icom Antenna 2 with total mechanical and electrical compatibility.
-
Integrated Shock Spring: The reinforced chrome spring absorbs physical impacts, extending the lifespan of both the antenna and the vehicle mount.
-
3 dBi High-Gain Performance: Provides superior signal propagation and increased reception sensitivity compared to standard unity-gain antennas.
-
Rugged Chrome Construction: The base loaded coil is housed in high-impact ABS and plated brass for maximum corrosion resistance in harsh weather.
-
Standard NMO Interface: Compatible with all standard NMO mobile mounts, allowing for versatile installation on trucks, vans, and emergency vehicles.
-
Tunable Whip Design: The 49-inch stainless steel whip can be field-trimmed using the provided cutting chart for optimized VSWR at specific frequencies.

Frequently Asked Questions
-
Is this antenna a direct swap for the Icom Antenna 2? Yes, the TE Connectivity B1443S provides the same mounting footprint and VHF performance as the discontinued Icom Antenna 2.
-
Does this require a magnetic mount? It requires an NMO mount. This can be a magnetic mount, a trunk-lip mount, or a permanent through-hole mount depending on your vehicle's requirements.
-
Can I use this without a metal roof? No, the TE Connectivity B1443S requires a metallic ground plane (typically the vehicle's roof or trunk) to achieve the specified 3 dBi gain and proper VSWR.
