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

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.
