Kimpok KP-T1220A – Compact 1.2 GHz Analog VTX for FPV and UAV Projects
The Kimpok KP-T1220A is a lightweight analog video transmitter designed for FPV drones, compact UAV platforms, remote monitoring, and light inspection work. It combines compact dimensions, up to 2 W transmit power, and a wide 7–36 V DC input range, making it easy to integrate into many hobby-grade video transmission setups.
One of the biggest advantages of the KP-T1220A is its excellent balance of high output power and low weight. At only about 16 g without the antenna, it is a great choice for builds where stable image transmission, low latency, and minimal added payload really matter.
- 1.2 GHz analog VTX for FPV systems and custom video links
- Selectable output power: 25 mW or 2000 mW
- 8 working channels across the 1080–1360 MHz range
- Low latency transmission below 30 ms
- Wide power input: 7–36 V DC, compatible with 2S–8S LiPo setups
- Compact size: 38 × 36 × 11 mm
- Low weight: approx. 16 g without antenna
- CNC aluminum housing for improved durability and heat dissipation
- 20 × 20 mm M2 mounting pattern for easy installation
Switch Between 25 mW and 2 W to Match Your Flight Style
The Kimpok KP-T1220A gives you the flexibility to choose between two transmission power levels. The 25 mW mode is ideal for short-range flights, bench testing, FPV setup work, or environments where reducing interference is important. The 2 W mode delivers a much stronger signal, making it better suited for longer-range flights, terrain monitoring, light industrial inspection, and exploratory FPV missions.
This quick power adjustment makes the transmitter especially practical for pilots who use the same drone in different scenarios—from short local test flights to more demanding outdoor operations.
| Operating Mode | Recommended Use | Estimated Range in Open Area |
|---|---|---|
| 25 mW | Short FPV flights, testing, low-interference operation | Up to 500 m with a 2.0 dBi omnidirectional antenna |
| 2 W | Medium- and long-range flights, monitoring, light inspections | Up to 3 km with a 2.0 dBi omnidirectional antenna |
| 2 W with higher-gain antenna | Extended FPV missions and field applications | Up to 6 km with a 5.8 dBi antenna |
Stable 1.2 GHz Analog Video Transmission with Low Latency
This analog Kimpok transmitter operates across the 1080–1360 MHz range and supports 8 selectable channels. With 40 MHz channel spacing, it is easier to choose a suitable frequency for your setup and reduce interference between nearby devices. The 1.2 GHz band is often chosen for FPV applications where signal stability and good propagation are important.
The unit uses FM analog video transmission and supports CVBS input as well as both PAL and NTSC formats, so it can work with many analog FPV cameras. With latency below 30 ms, it offers a smooth real-time view that is especially useful during fast flying, precise maneuvering, and inspection tasks.
| Channel | Transmit 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 |
Lightweight Design, CNC Aluminum Case, and Efficient Cooling
The KP-T1220A was built with lightweight FPV drones and compact UAV platforms in mind. Its 38 × 36 × 11 mm size and approx. 16 g weight without antenna make installation easy, even in tighter builds where every gram and every millimeter count. The 20 × 20 mm M2 mounting standard also helps with integration into many popular frames and compact drone projects.
The CNC-machined aluminum housing improves mechanical durability and helps dissipate heat during high-power operation. When running in 2 W mode, proper airflow is recommended, especially if the transmitter is installed in an enclosed space or used in warmer conditions.
- CNC aluminum enclosure improves durability and thermal performance
- Compact body makes it easier to fit into smaller FPV builds
- Low weight helps minimize the impact on flight performance
- 20 × 20 mm M2 mounting fits many lightweight drone configurations
- Built-in protections support safer everyday operation
