Kimpok Analog Transmitter KP-T1240

Kimpok KP-T1240 Analog VTX Transmitter 1.2 GHz up to 4 W
Kimpok KP-T1240 is a powerful 1.2 GHz analog video transmitter designed for FPV setups, drone video transmission, and hobby projects that need a stronger and more reliable video signal. With selectable output power levels of 25 mW, 2000 mW, and 4000 mW, it can be easily adjusted for short test flights, everyday flying, or more demanding long-range field use.
This model stands out with its durable aluminum housing, built-in heatsink, active cooling fan, and a wide DC 7-36 V input range. If you are looking for a high-power 1.2 GHz analog VTX with practical channel switching and adjustable transmission power, the KP-T1240 is a solid choice for hobby FPV applications.

Adjustable Power up to 4 W for Flexible Range Setup
The KP-T1240 lets you match transmission power to your flying conditions. The 25 mW mode is great for bench testing, short-range flights, or reducing interference in tighter environments. The 2000 mW and 4000 mW modes are better suited for situations where a stronger analog video signal is needed, such as outdoor FPV flying or longer-distance video transmission.
Power settings are changed using the button on the housing, while a green LED indicates the current operating mode. The transmitter also supports Pit Mode, making setup and service work safer by limiting signal output during configuration.
| Power Mode | Typical Use | LED Indication |
|---|---|---|
| 25 mW | Testing, short flights, reduced interference | Green LED flashes once |
| 2000 mW | Longer-range FPV flights, stronger signal | Green LED flashes twice |
| 4000 mW | More demanding field setups | Green LED flashes three times |
| Pit Mode | Setup and maintenance | Green LED stays on continuously |
9 Channels in the 1.2 GHz Band and Easy Button Control
The Kimpok KP-T1240 analog transmitter supports 9 operating channels. Channel switching is handled with the Band & Channel button, while the current channel is shown by a red LED. Each short press moves to the next channel, making it easy to match the transmitter to your receiver and current operating conditions.
This simple control method is especially convenient when setting up an FPV system, as it does not require a complicated menu or extra tools. You can quickly check settings, select the right channel, and get ready to fly.
| Channel | Frequency |
|---|---|
| CH1 | 1080 MHz |
| CH2 | 1120 MHz |
| CH3 | 1160 MHz |
| CH4 | 1200 MHz |
| CH5 | 1240 MHz |
| CH6 | 1280 MHz |
| CH7 | 1320 MHz |
| CH8 | 1360 MHz |
| CH9 | 1258 MHz |
Aluminum Housing, Heatsink, and Cooling Fan for Stable Operation
Because of its high output power, the KP-T1240 is equipped with an aluminum housing, heatsink, and cooling fan to help manage heat effectively. This design supports stable performance and helps protect the electronics during more intensive use.
The unit also includes thermal protection. If the transmitter temperature exceeds 100°C, transmission power is automatically reduced by one level. If the temperature remains too high, the power can continue to drop step by step down to 25 mW. Once the temperature falls back to around 95°C, the transmitter returns to the previously selected power level.
- Aluminum housing improves durability and heat dissipation
- Heatsink increases cooling surface area
- Cooling fan supports operation at higher power levels
- Thermal protection helps reduce the risk of overheating
- Leave enough space around the unit for proper airflow during installation
