SKU CH-HNEM-EX605

A two-channel 27 MHz transmitter and receiver board set with antennas for remote-control cars and trucks

  • 2-channel 27 MHz radio control for car and truck toys
  • Transmitter and receiver boards included in one set
  • Two antennas supplied at 26 cm and 18.5 cm lengths
  • Compact PCB sizes of 27×40 mm and 24×35 mm
  • Green metal construction ready for universal installation

27MHz Transmitter and Receiver Set

This 27MHz radio system includes a transmitter board and a receiver board designed for remote control car and truck toys. The two-channel circuit boards operate on a 27MHz electronic frequency and come with two antennas measuring approximately 26cm and 18.5cm respectively. The set is supplied new and intended for universal use in compatible toy vehicles.

Included Boards and Antennas

The package provides one transmitter board measuring approximately 27x40mm and one receiver board measuring approximately 24x35mm, both constructed from green metal material. Two antennas are bundled to establish the wireless link between the boards. No additional accessories shown in product imagery are included with this set.

27MHz Frequency Constraints

The system uses a fixed 27MHz frequency for wire control communication, which limits operation to a single channel pair without frequency-hopping capability. Range and reliability depend on antenna positioning and local radio interference at this legacy band. The boards require integration into a host vehicle's electronics and are not suited for applications demanding modern spread-spectrum protocols or multi-model coexistence.

Questions about this item

Will the 26 cm transmitter antenna or 18.5 cm receiver antenna need periodic replacement?

The wire antennas are passive metal elements with no moving parts; they only require replacement if physically damaged or corroded.

What limits continuous operation of the 27 MHz transmitter board first?

The small 27 x 40 mm PCB has no heatsink, so thermal buildup in the RF output stage becomes the practical duty-cycle limit.

How much heat does the 24 x 35 mm receiver board produce when powered all day?

The compact receiver draws only milliwatts from the car's battery pack, so it stays barely warm to the touch during extended runs.
