Video 受信機 VRX KP-R4959 80CH Version 4.9G to 5.8G

Buy a Kimpok KP-R4959 video receiver for a stable signal at frequencies of 4.9–5.9 GHz

The module accepts analog video signals in the extended range 4990–5945 MHz. The device is suitable for FPV drones, racing quadcopters and ground stations. 80 channels and high sensitivity -95 dBm provide clear images even in noisy environments. The frameless design allows the receiver to be built into the housings of other devices. It's a reliable choice for long-distance flights and fast-paced racing.

• 4.9–5.9 GHz range for operation on less congested frequencies.
• 80 channels in 10 frequency grids for flexible configuration.
• High sensitivity -95 dBm for a stable signal over a distance.
• Power supply from 7 to 36 V for compatibility with most batteries.
• Compact weight 14.2 g and dimensions 44x27x27 mm for easy integration.

The module receives an analog signal in the range 4990–5945 MHz. The built-in FM/PLL demodulator converts it into a composite video signal (CVBS). 75 ohm output impedance and 1V level ensure compatibility with FPV goggles and monitors. Channel switching is performed by a button on the board, the selected channel is displayed by eight LEDs. RSSI output (1.3–0.7 V) allows you to control the signal level in real time. Two SMA connectors connect external antennas to improve reception.

Features of the KP-R4959 model

The main feature is operation in the extended range of 4.9–5.9 GHz, which avoids interference from consumer electronics and electronic jamming devices. The frameless design simplifies the integration of the module into existing systems. Two SMA connectors make it possible to connect antennas with improved characteristics. Wide power supply range (7–36 V) allows the module to be used with various energy sources. The device does not have internal memory and serves solely to receive a signal with subsequent output through the AV output.
