Kimpok Analog Transmitter ALPHA 5

Kimpok ALPHA 5 Analog VTX is a high-power video transmitter designed for demanding FPV builds, long-range drones, RC models, and custom video systems where a stable analog video signal really matters. With up to 5W output power, 80 channels, 12–28V input, Smart Audio support, and a 5V output for additional gear, this VTX is a strong choice for hobbyists who want serious performance from their analog FPV setup.

Built for high-output operation, the ALPHA 5 features a heatsink and active cooling fan to help manage temperature under load. Its 30.5 x 30.5 mm mounting pattern also makes installation easier in many popular FPV frames and RC platforms.

Up to 5W Output Power for Strong, Stable FPV Video

The standout feature of the Kimpok ALPHA 5 is its powerful RF output. You can choose from five power levels, making it easy to match the transmitter to your flying style, test environment, or long-range build requirements.

• 25mW – ideal for bench testing, setup, and short-range use.
• 1W – a versatile power level for standard FPV applications.
• 2W – stronger signal performance for more demanding conditions.
• 3W – high output for advanced analog FPV configurations.
• 5W – maximum transmit power for builds that need the strongest possible analog VTX signal.

This wide power range gives hobby pilots the flexibility to use the ALPHA 5 both for simple tuning sessions and for more challenging FPV missions where signal strength is a priority.

80 Channels for Flexible Frequency Setup

With support for 80 channels, the Kimpok ALPHA 5 offers plenty of flexibility when configuring your FPV system. A wider channel range makes it easier to match your receiver, reduce interference, and run multiple setups in the same area.

• 80CH support – broad channel selection for analog video transmission.
• Easier receiver matching – more freedom when choosing frequencies.
• Better interference management – selecting a less crowded channel can improve image quality.
• Great for group flying – useful when several FPV systems operate nearby.
• Suitable for RC and FPV builds – ideal for drones, FPV platforms, and custom video installations.

Smart Audio Support for Quick and Convenient Control

The ALPHA 5 supports Smart Audio, allowing compatible flight controllers to manage VTX settings without direct physical access to the module. That is especially useful once the transmitter is installed inside a tight FPV frame.

• Smart Audio control – adjust transmitter settings through a compatible FPV system.
• Easier post-install configuration – less need to remove parts or access the module manually.
• JST 8-pin connector – practical wiring solution with dual 12–28V input and dual ground.
• 5V output – handy for powering an additional system component.
• Pin labels on the housing – simpler and faster installation.

Active Cooling and Heatsink for High-Power Operation

Running a high-power analog VTX generates heat, so the Kimpok ALPHA 5 is equipped with a built-in cooling fan and heatsink to support more stable operation. This is especially important when using the higher 3W and 5W power modes.

• Built-in fan – active cooling during operation.
• Heatsink design – improved heat dissipation surface area.
• More stable high-power performance – designed for intensive hobby use.
• Compact form factor – dimensions of 68 x 36 x 15 mm help with installation.
• Standard mounting pattern – 30.5 x 30.5 mm spacing fits many popular FPV layouts.

Technical Specifications

The Kimpok ALPHA 5 Analog VTX is built for hobby-grade FPV systems that require strong analog video transmission and flexible installation options. The manufacturer recommends using a 6S battery. Current draw is rated at 1.7A at 12V or 800mA at 28V.
