The RF Transmitter is a compact, handheld device with a rectangular body, featuring a small antenna protruding from the top. Its surface is primarily metallic with a matte finish, showing signs of wear and tear such as scratches and minor dents, indicating frequent use. The front panel includes a small LED indicator light and a few buttons for operation, with a slightly raised, grooved texture for better grip. The color scheme is utilitarian, with dark grays and blacks, accented by the faint glow of the LED when active.
