Item description

Hybrid J-Pole Antenna – Precision-Tuned for 1280 MHz

Operating in the 1.2 GHz band requires precision, efficiency, and mechanical resilience—especially for airborne and mobile systems. Our 1280 MHz hybrid J-Pole antenna is designed specifically for high-frequency applications where compact size, reliability, and signal integrity are critical.

The J-Pole Advantage at Higher Frequencies

While the J-Pole is known for its simplicity, it scales very effectively into higher frequencies. At 1280 MHz, its shorter physical length allows for even more compact implementations while retaining key benefits:

  • Direct 50-ohm feed via a quarter-wave stub

  • No baluns or tuning circuits needed

  • Balanced radiation pattern with no ground plane required

  • Low-profile structure, perfect for drones and mobile equipment

Ideal Use Cases

  • FPV and digital video transmission

  • High-frequency drone telemetry (UAV/UAS)

  • Advanced RF sensing and data uplinks

  • Short-range microwave links

  • Compact ground or mobile stations

Materials & Construction

  • Stub and base: FR4 PCB with copper traces

  • Radiator: Stiffened PVC-coated steel wire

  • Connector: Gold-plated SMA

  • Form factor: Slim and rugged for field use

Electrical Characteristics

  • Center Frequency: 1280 MHz

  • Bandwidth: ≥ 20 MHz @ RL < -13 dB

  • VSWR: < 1.15 at center frequency

  • Gain: ~2.5 dBi (omnidirectional in H-plane)

  • Weight: < 10 grams

  • Connector: SMA (male standard)

  • Tuning: Individually calibrated and tested

Deployment Options

  • Short Version (Rigid):

    • 6 cm RG402 semi-rigid coax

    • Lightweight and impact-resistant—ideal for UAV frames or pods

  • Long Version (Flexible):

    • 1 meter RG316D flexible coax

    • Mount to mast, tripod, or mobile kit

Applications

  • FPV systems with low-latency video transmission

  • L-band UAV/UAS telemetry and command links

  • Microwave data relays for robotics or IoT

  • Emergency field communications

  • Portable ground control stations

Built to Withstand Real Conditions

Designed with harsh environments in mind, this antenna’s hybrid construction ensures:

  • High mechanical strength (resists bending and shocks)

  • Excellent weather resistance (moisture, dust, UV)

  • Consistent electrical performance across temperature swings

How It Stacks Up Against the Bardpole

The Bardpole has earned its reputation—no argument there. But our Hybrid J-Pole brings its own advantages to the table:

  • Just as precise (or better) – Matches or exceeds the Bardpole’s tuning and bandwidth.

  • Built tougher – Spring steel core resists bends, drops, and vibrations.

  • More flexibility – Choose your cable length and connector type to fit your setup.

  • Same compact profile – Lightweight and streamlined for FPV and telemetry use.

  • No guesswork – Every antenna is individually tuned, so performance stays consistent.
