The Jetfon DB-85F dual band antenna (SMA) -2m/70cm dual band portable antenna is a commercial-grade, ultra-compact tactical radiating element precision-engineered to deliver high-integrity voice and data synchronization for handheld transceivers. Designed for space-saving utility and high field reliability, this low-profile vertical whip optimizes portable radio setups across emergency dispatch grids, indoor facility coordination workflows, security details, and high-volume B2B radiocommunication accessory wholesale distribution networks looking to source responsive, specialized transceiver accessories.
The internal RF architecture of the Jetfon DB-85F is built upon a high-efficiency type 1/4 wave resonant structure that delivers dual-band coverage across core VHF and UHF allocations, matching the popular 2-meter and 70-centimeter bands. Despite its small mechanical footprint, the matching network handles a robust maximum power rating of 10W continuous carrier output. A highly innovative engineering feature of this model is its integrated top-cap active telemetry loop, which provides a bright LED indicator in TX. The diode glows in a sharp, clear RED color the moment the connected walkie-talkie begins transmitting, giving operators immediate visual verification of active RF power flow on the service bench or out in the field.
Housed in a ruggedized, highly flexible polymer casing that easily absorbs shocks and bending forces, this lightweight portable antenna has a net structural length of 8.5 cm and registers an incredibly light weight of just 18gr, minimizing physical torque strain on the transceiver’s upper terminal mount. This specific hardware variant is terminated in a high-retention, low-attenuation SMA female connector base with gold-plated contact components to secure a stable impedance bridge (note: this model is also available with an SMA male interface layout under part reference number 0283). Providing an excellent blend of field discretion, visual diagnostic tracking, and out-of-the-box system compliance, this turnkey replacement antenna guarantees absolute operational readiness across your corporate hardware fleet.
