ЧДБ RX 150 telescopic dipole receiver antenna without mounts — a collapsible receiving dipole antenna from the Ukrainian manufacturer ЧДБ (Cherkasydronbud) for the RX onboard receiver in 150 MHz radio control systems (MIL ELRS, TX+RX 150 kits). When extended, its length is 96.5 cm — optimal for stable reception of control signals on UAVs and UGVs.

The telescopic design is convenient for transport and rapid field deployment: the antenna takes up minimal space in a case when collapsed and is ready for flight in minutes. Gain ~2 dBi, impedance 50 Ohm, bandwidth with VSWR < 1.5 — approximately 10 MHz in the 150 MHz sub-band (by analogy with the ЧДБ TX 150 telescopic antenna).

Key Features

• Type: telescopic dipole, receiving antenna for RX.
• Operating range 150 MHz (ЧДБ 150–153 MHz systems).
• Length when extended: 96.5 cm.
• Gain ~2 dBi, impedance 50 Ohm.
• Collapsible design — convenient transport and deployment.

Key Advantages

• Compact for transport: telescopic sections take up less space than a fixed 96.5 cm mast.
• Compatible with MIL ELRS 150: standard option for ЧДБ TX+RX 150 kits.
• Alternative to spiral RX: simpler installation without strict requirements for spiral polarization (vertical dipole).
• ЧДБ in-house production: compatibility with manufacturer's receivers and firmware.
• Easy installation: mounting on the frame after RX soldering — minimal preparation time.

Areas of Application

• Onboard receiver RX Mk4 150 on FPV/reconnaissance UAVs.
• ЧДБ TX+RX 150 MHz radio control kits (options with telescopic RX).
• Replacement or additional RX 150 antenna in the field.
• UGVs and platforms with a 150 MHz control channel in an EW zone.

Package Contents

• Telescopic dipole antenna RX 150.

Technical Specifications

Operating Warnings

• Extend the antenna fully to 96.5 cm before flight — partially extended sections degrade reception.
• Do not damage the telescopic sections when collapsing; avoid excessive bending.
• Install the mast vertically relative to the frame, if drone layout allows — this ensures more stable dipole operation.
• Secure the mount on the frame so that the antenna does not interfere with propellers and does not vibrate.
• Protect the IPEX connector and cable to the receiver; do not strain the feeder when rotating the camera/frame.

The ЧДБ RX 150 telescopic antenna is a practical onboard option for 150 MHz: convenient telescopic design and compatibility with the ЧДБ MIL ELRS lineup.
