Kimpok ALPHA 8 analog transmitter

Kimpok ALPHA 8 is a seriously powerful analog FPV video transmitter (VTX) built for hobbyists who need a strong, stable video signal in advanced setups. With up to 8W output power, 80 channels, and an input voltage range of 12–28V, this model is a great fit for long-range FPV platforms, RC models, custom analog video systems, and demanding drone builds where signal strength and easy flight controller integration really matter.

The ALPHA 8 features an SMA antenna connector, a standard 30.5 x 30.5 mm mounting pattern, and a practical JST 8-pin cable connector with dual power input and dual ground. A built-in heatsink and cooling fan help manage heat during high-power use, while Smart Audio support makes transmitter setup and tuning much easier from a compatible FPV system.

Up to 8W Output Power for Advanced FPV Setups

The standout feature of the Kimpok ALPHA 8 is its very high output power. The transmitter supports multiple power levels: 25mW, 1W, 3W, 5W, and 8W, so you can match performance to your flying environment and setup requirements. Lower power is ideal for bench testing and short-range use, while the full 8W mode is designed for applications where the strongest possible analog video signal is the priority.

• 25mW – ideal for setup, testing, and short-range use.
• 1W – a versatile power level for typical FPV applications.
• 3W – stronger signal output for more challenging conditions.
• 5W – high transmission power for advanced analog video builds.
• 8W – maximum output for the most demanding FPV installations.

This wide adjustment range makes the ALPHA 8 a flexible choice for everything from safe low-power tuning to high-output VTX use in long-range or high-interference environments.

80 Channels for Flexible Frequency Setup

With support for 80 channels, the Kimpok ALPHA 8 analog transmitter gives you more freedom when matching frequencies with your receiver and adapting to different flying conditions. A wider channel selection is especially useful for group flights, testing multiple FPV systems, and operating in places where interference is present or several transmitters are running at once.

• 80CH support – broad channel selection for analog video transmission.
• Easier receiver matching – more flexibility when choosing frequencies.
• Lower risk of channel conflicts – useful when multiple FPV systems are nearby.
• Designed for analog FPV video – works well in classic analog setups.
• Convenient parameter control – settings can be adjusted via Smart Audio.

Smart Audio and Clear Connection Layout for Easy Integration

The ALPHA 8 supports Smart Audio, allowing you to control transmitter settings directly from a compatible flight controller. That is a big plus in FPV drones and RC models where the VTX may be hard to access once installed. It makes changing settings quicker and more convenient without needing to remove or reposition the transmitter.

The PCB includes clearly labeled connection points to simplify installation, including 5V-OUT, GND, VIDEO, TBS, Dual Power GND, and Dual 12–28V IN. The board also includes a MIC marking, making component identification easier during wiring and setup.

• Smart Audio – easy transmitter control through a compatible FPV system.
• 5V-OUT – 5V output for additional system components.
• VIDEO – analog video signal input.
• Dual 12–28V IN – dual power input for reliable connection.
• Dual Power GND – dual ground for the power circuit.
• JST 8-pin connector – clean and organized wiring for FPV integration.

Active Cooling and Heatsink for High-Power Operation

A VTX capable of up to 8W output needs effective thermal management. The Kimpok ALPHA 8 is equipped with a built-in cooling fan and heatsink to support stable operation at higher power levels. This is especially important in setups where the transmitter runs for longer periods or operates with high RF output.

• Built-in fan – active cooling during transmitter operation.
• Heatsink – improved surface area for heat dissipation.
• Better stability at high power – designed with 5W and 8W settings in mind.
• Compact form factor – dimensions of 68 x 36 x 15 mm help with installation.
• 30.5 x 30.5 mm mounting pattern – compatible with many popular FPV builds.

When using the highest power levels, proper airflow around the module is strongly recommended. Correct installation and a connected antenna are essential for both transmitter lifespan and video transmission quality.
