MAIN AMPLIFIER 3XUHF+DAB/B3-UHF+FM AGC

is a programmable, compact amplifier designed for channel-specific filtering or channel switching of DVB-T/T2 channels. The device features a built-in 4G/5G SAW-LTE filter to block access from mobile frequencies to the amplifier and distribution network. Real-time automatic gain control maintains the output level at the set value, even if input levels from the antenna vary. Thanks to its high output level, the DSP35-5G is ideally suited for medium and large antenna networks such as row and apartment buildings. No separate programming device is required, as the DSP35-5G can be programmed manually via the device’s front panel, automatically via scan, or using the LEMGUI Android/Windows PC software. Packing size: 1/5 pc. Features
