The ChDB RX 310–330 dipole receiver antenna (1012) is a receiving dipole antenna from the Ukrainian manufacturer ChDB (Cherkasydronbud) for control radio channels in the 310–330 MHz range (resonance 320 MHz). It is designed for installation on RX UAV and UGV receivers as part of MIL ELRS systems and other ChDB kits in this range.
Linear vertical polarization (V), gain 2.7 dBi, bandwidth 20 MHz at VSWR < 1.5. Connection via RG1.13 cable (300 mm, 50 Ohm) with IPEX Female connector. Includes a plastic mount (mount and mast) for secure attachment to the drone frame.
Lightweight design (19 g), dimensions 450×70 mm, materials — aluminum and plastic. Optimal matching with ChDB receivers in the 310–330 MHz sub-band ensures stable reception of the control signal on board without unnecessary feeder losses.
Key Features
- Type: dipole, receiving antenna for RX.
- Operating range 310–330 MHz, resonance 320 MHz.
- Gain 2.7 dBi, impedance 50 Ohm.
- Polarization: linear vertical (V).
- Cable RG1.13, length 300 mm, connector IPEX Female.
- UAV frame mounting: mount and mast included.
Key Advantages
- Narrowband tuning: 20 MHz band with low VSWR for stable reception at 320 MHz.
- Low weight: only 19 g — minimal load on the FPV/UAV frame.
- Ready-made mount: no need to select a separate mount for the mast.
- ChDB's own production: compatibility with the manufacturer's receivers and communication systems.
- Durable materials: aluminum radiator and plastic mounting housing.
- Short 300 mm feeder: lower losses compared to long self-made cables.
Areas of Application
- Onboard UAV control receivers at 310–330 MHz frequencies.
- Ground and aerial platforms with MIL ELRS radio link (ChDB).
- Replacement or additional equipping of the standard RX antenna in the field.
- Operation in conditions where vertical polarization and 50 Ohm matching are important.
Package Contents
- RX 310–330 MHz dipole antenna with cable and IPEX connector.
- Plastic mount: mount and mast for frame installation.

Operating Warnings
- Install the antenna with vertical polarization (V) as designed — otherwise, reception will degrade.
- Do not bend or damage the RG1.13 cable near the IPEX output.
- Ensure that the receiver and transmitter operate in the 310–330 MHz range — outside this band, VSWR increases.
- Secure the mount and mast to the frame so that the antenna does not interfere with propellers and does not vibrate during flight.
The ChDB RX 310–330 antenna is a standard solution for onboard reception at 320 MHz: precise band tuning, light weight, and a ready-made mount simplify installation on UAVs and UGVs.
