NEW CTE High Efficiency FM Broadcast Transmitters TX05-HE 500W TX1-HE 1kW General Description The new 500W TX05-HE and 1kW TX1-HE are the first CTE FM Transmitters based on the last generation of RF Devices that greatly increases the total equipment efficiency, reducing dimension and weight, granting very high reliability and stability on the performances. The new line apply the same controls, user interface and FM modulator platform used on the actual CTE Transmitter series. Full compatibility is guaranteed between actual and new lines.
