Straight (Rubber) Antenna, Ham Radio 410~512MHz, Omni Radiation, Unity Gain with SMA Male Connector 

Ultra-Compact Fixed Stubby UHF Ham Radio Solution

The commercial-grade UHF flexible stubby antenna is engineered for high-durability, close-range wireless communication across the 410 to 512 MHz frequency spectrum. This range seamlessly covers the amateur radio 70-centimeter band, land mobile radio (LMR) systems, and standard PMR/GMRS/FRS operational frequencies. Delivering a unity gain (0 dBd or 2.15 dBi) profile, this antenna acts as a perfect isotropic-style radiator, projecting a broad spherical radiation pattern. This characteristic makes it highly effective for rugged, multi-elevation tactical communications, indoor security detachments, and dense urban environments where complex physical structures cause heavy signal reflection and scattering.

Measuring a mere 1-3/4 inches in length, this ultra-low-profile antenna features a rigid yet flexible thermoplastic (rubber) radome that protects the internal copper radiating element from heavy impacts, abrasion, and moisture. Its "stubby" design drastically reduces physical snags and mechanical stress on the radio's antenna port compared to full-length whip antennas, making it a preferred choice for belt-worn handheld transceivers and compact field testing equipment. The base terminates in a standard SMA Male (Plug) connector—featuring internal threads and a center male pin—ensuring a secure, vibration-proof direct mechanical connection to compatible handheld radios and RF equipment without the need for cumbersome adapters.
