Swivel (Rubber) Antenna, Ham Radio 144/430MHz, Omni Radiation, 2/3dBi Gain with BNC Male Connector
Flexible Articulating Dual-Band Coverage
The commercial-grade 144/430 MHz dual-band swivel rubber antenna is precision-engineered for versatile handheld and portable amateur radio operations across the VHF (2m) and UHF (70cm) bands. Offering a well-balanced 2 dBi gain on VHF and 3 dBi gain on UHF, this antenna delivers an efficient omnidirectional (360°) radiation pattern. This pattern provides excellent horizontal propagation for simplex field communications, emergency services, and reliable repeater access.
The defining feature of this 15-inch antenna is its integrated swivel/articulating base, which allows the radiator to bend and rotate. This flexibility enables operators to maintain a vertical antenna orientation for optimal polarization and signal performance, whether the transceiver is carried on a belt, mounted on a chest rig, or resting on an uneven surface. Encased in a rugged, highly flexible injection-molded rubber jacket (often referred to as a "rubber ducky" style), the internal radiating elements are completely protected against impact, moisture, and rough handling. The antenna terminates in a standard BNC Male (Plug) connector, offering a secure, quick-disconnect twist-lock interface that permits rapid deployment and hardware transitions.
