Kimpok ALPHA 16 analog transmitter

Kimpok ALPHA 16 is a high-power analog FPV video transmitter built for demanding hobby-grade drone and RC setups. With adjustable output power up to an impressive 16 W, Smart Audio support, an SMA antenna connector, and a 5 V output for powering an FPV camera up to 500 mA, this VTX is a serious choice for users who need strong signal performance, stable operation, and efficient cooling in advanced analog video systems.

Designed for high-load applications, the ALPHA 16 operates on 19–28 V input and requires a capable power source. To handle the current draw safely, the manufacturer uses dual positive power wires and dual ground wires, all of which must be connected correctly. The unit also features an LED display, function button, and a built-in heatsink that should never be removed.

Up to 16 W Output Power for Serious Analog FPV Range

The standout feature of the Kimpok ALPHA 16 is its exceptionally high transmit power. Multiple power levels let you tune the VTX for everything from bench setup and short-range testing to long-range and high-demand FPV applications.

• 25 mW – ideal for testing, setup, and short-range use.
• 1 W – a practical setting for standard FPV video transmission.
• 3 W – stronger signal output for more challenging environments.
• 5 W – high-power mode for advanced analog FPV systems.
• 8 W – very powerful output for expanded FPV installations.
• 16 W – maximum performance for the most demanding use cases.

Because this is a very high-power VTX, proper installation is essential. Always make sure the antenna and antenna lead are securely connected to the SMA connector before powering the unit on.

19–28 V Input and Dual Power Wiring for High Current Loads

The Kimpok ALPHA 16 is designed to run on 19–28 V input voltage, with a peak operating current of 3 A. The recommended power supply should be capable of delivering more than 4 A for reliable performance. Due to the high power and current demand, this transmitter uses dual power input wires and dual ground wires. Both positive wires and both ground wires must be soldered correctly—do not connect only one wire from each pair.

• 19–28 V input – suitable for powerful FPV builds.
• 3 A operating current – requires a robust power source.
• Recommended supply above 4 A – provides safer operating headroom.
• Dual 19–28V IN – dual power wires for high-load operation.
• Dual Power GND – dual ground wires required for proper connection.
• JST 6-pin connector – convenient wiring for power and signal lines.

Smart Audio, LED Display, and Easy On-Board Setup

The Kimpok ALPHA 16 analog transmitter supports Smart Audio, allowing VTX settings to be adjusted from a compatible FPV system. This is especially useful in builds where the transmitter becomes difficult to access after installation, making tuning faster and more convenient without taking the setup apart.

The unit also includes a function button and LED display for quick status checks and manual setting changes. Please note that this model does not support a microphone, so it is intended primarily for analog video transmission.

• Smart Audio – easy VTX control from a compatible flight system.
• LED display – quick view of current operating status.
• On-board function button – manual access to selected settings.
• 5V camera output – powers an FPV camera up to 500 mA.
• No microphone support – focused purely on video transmission.
• SMA connector – standard antenna connection for FPV systems.

Heatsink and Airflow-Friendly Installation

Running at up to 16 W generates a significant amount of heat, so the ALPHA 16 comes equipped with a heatsink to help manage temperature. It should not be removed. For the best cooling performance, the manufacturer recommends mounting the transmitter on the top layer of the drone frame, where airflow is strongest during flight.

• Integrated heatsink – helps dissipate heat during high-power operation.
• Do not remove the heatsink – it is essential for thermal management.
• Top-frame mounting recommended – improves airflow and cooling.
• 30.5 x 30.5 mm mounting pattern – compatible with popular FPV frame layouts.
• 68 x 36 x 15 mm dimensions – compact size for a very high-power VTX.

As with any powerful video transmitter, never power the unit on without an antenna attached. Operating without an antenna or with an improperly connected pigtail may permanently damage the module.
