1. Overview
FM YXHT-2 4000W/LIGHT stereo FM radio transmitter is an integrated high-quality FM transmitter that stereo-encodes the input left and right channel audio signals and adjusts the FM modulation to the broadcast band, then RF amplify to the 4000W output power for wireless broadcasting. The transmitter adopts the most advanced software radio technology to achieve the international leading level of product performance indicators.
With a new large-scale field-programmable gate array (FPGA) and direct digital frequency synthesis (DDS) technology at up to 5G, the product achieves the highest technical specifications in the industry to date, providing listeners with a CD-like sound experience.

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
