Package 1500W FM transmitter complete set include the 1500W FM transmitter, dipole antenna, 30meters coaxial cable. It is a economic complete package kit for radio station broadcasting.

1500W FM Transmitter Overview

This 1500W FM transmitter adopts the concept of simple design and integrates the exciter and power amplifier, output filter, switching power supply, etc into a 2U high 19-inch standard case. This advanced design reduces the number of connection cables and improves the overall efficiency of the transmitter, making it more reliable and easier to operate.

This 1500W FM Transmitter is 2U 19-inch all-aluminum standard chassis. 3.5-inch LCD display, PLL digital phase-locked loop frequency modulation technology, CD sound quality, the final power amplifier uses high standing wave ratio resistant LDMOS transistors. This 1500W FM transmitter can input analog audio signal or analog modulation signal, and AES / EUB digital signal.

Functional features
