Description

The TBS Triumph-Stub antenna represents a significant evolution in 5.8GHz circular polarized antenna design for FPV applications. Moving beyond traditional cloverleaf configurations, it employs a refined stub design engineered specifically for the demands of drone video transmission, offering a superior balance of signal clarity, range, and physical resilience.

Its construction prioritizes crash survivability with a unique foam-filled enclosure that is ultrasonically welded shut, creating a sealed unit that protects the internal antenna elements from moisture and physical damage. The use of heavy-duty, semi-rigid RG402 cable with a double jacket further ensures the antenna can withstand the repeated impacts and flexing common in FPV racing and freestyle.

Key Features

  • Advanced Stub Design: Engineered for optimal 5.8GHz performance, providing excellent signal purity and range with minimal multipath interference.
  • Ultra-Durable Construction: Features an ultrasonic welded, foam-infused plastic housing that absorbs impacts and protects the internal radiating element.
  • Heavy-Duty Cable: Utilizes double-jacket semi-rigid RG402 cable, offering superior strain relief and resistance to kinking or breaking during crashes.
  • High-Quality Connector: Equipped with a precision SMA connector (LHCP) ensuring a secure, low-loss connection to your video transmitter or receiver.
  • Lightweight & Compact: The stub form factor keeps weight under 10 grams and presents a low-profile, aerodynamic shape ideal for competitive and micro drones.
  • Rigorous Testing: Each antenna is manufactured and tested to the highest standards, a collaboration between TBS and antenna expert IBcrazy.

Applications

  • Lightweight 5-inch and 3-inch FPV racing drones where every gram counts and durable antenna mounting is crucial.
  • Freestyle and cinematic FPV builds requiring reliable video link integrity through dense environments like forests and urban areas.
  • Micro and Whoop-class drones (e.g., 65mm-75mm) needing a compact, crash-resistant antenna solution for indoor and outdoor flying.
  • As a high-quality receiver antenna for ground station modules or FPV goggles operating on the 5.8GHz band.
  • Long-range exploration mini-quads where a robust, low-profile antenna helps maintain a clean video signal.

Frequently Asked Questions

Is the TBS Triumph-Stub antenna compatible with my 5.8GHz video transmitter?

Yes, the Triumph-Stub is designed for the 5.8GHz band (5500-6000MHz) and uses a standard SMA connector. Ensure your VTX or VRX has an SMA port and that you require Left-Hand Circular Polarization (LHCP). It is compatible with most common FPV systems like analog VTXs, DJI FPV Air Units (using an SMA adapter), and receiver modules.

How durable is this antenna for FPV drone crashes?

The Triumph-Stub is built specifically for crash resistance. Its key durability features include an ultrasonic welded and foam-infused plastic housing that absorbs impacts, and a heavy-duty, double-jacket RG402 cable that resists breaking from flexing or snagging. This makes it significantly more robust than antennas with standard silicone-jacketed cables.

What is the advantage of the stub design over a cloverleaf antenna?

The stub design offers a more aerodynamic and compact profile with less drag, which is beneficial for high-speed racing. It also provides a very consistent radiation pattern and good axial ratio (0.74), which translates to cleaner video signal reception with less multipath distortion in environments with signal reflections, compared to some traditional multi-lobe designs.
