Straight (Metal) Antenna, Ham Radio 144/430MHz, Omni Radiation, 2/3dBi Gain with BNC Male Connector 

High-Performance Dual-Band Amateur Radio Whip

The amateur-grade dual-band straight metal antenna is engineered for reliable, high-efficiency two-way radio communications across the popular VHF (144 MHz) and UHF (430 MHz) ham radio bands. Providing a balanced 2 dBi gain on VHF and a higher 3 dBi gain on UHF, this antenna utilizes an optimized collinear structure to flatten the vertical radiation pattern, projecting signals further toward the horizon. Its true omnidirectional (360°) horizontal coverage makes it ideal for maintaining steady contact with local repeaters and simplex stations while operating in mobile, tactical, or field-day environments.

Measuring 17 inches in length, this antenna is constructed with a rugged, resilient steel or alloy spring-whip design. This straight metal radiator is built to flex under stress and withstand mechanical impacts, making it far more durable than standard rubber duck antennas during outdoor field operations. The assembly terminates in a classic BNC Male (Plug) connector—a quick-disconnect, bayonet-locking interface featuring two radial lugs on the female side and a slotted collar on the male side. This snap-and-turn mechanism provides an exceptionally secure, vibration-proof RF connection and allows operators to swap antennas instantly on handheld transceivers, portable field rigs, or RF test equipment.
