The VHF transmission system is a device used in antenna feeding systems. It can combine multiple RF signals from channel equipment into a single signal and then transmit it to the antenna. This transmission system uses an efficient heat dissipation design, with all components integrated onto a heatsink, effectively enhancing heat dissipation efficiency. As a result, not only can the transmission power be increased, but multiple high-power signals can also operate normally at the same time. According to customer requirements, a fan cooling function can also be added to this system.
The operating frequency band, number of channels, and power capacity can all be customized.
Operating temperature: -30°C to 75°C.
