The new V51-204 offers extremely high quality dual UHF, FM and DAB high maximum input and output capability with filtering for 4G-800 LTE suppression.
This amplifier has two UHF inputs, UHF1 is filtered for channels 21-57 with DC powering for a masthead amplifier. This ensures high rejection of 4G-LTE above 790MHz. UHF input 2 is filtered for channels 21-60. For those who require channels above channel 57 they are advised to use this input, however additional 4G-LTE filtering may be required. A user test point -30dB is fitted at the output for test and measurement without disconnecting the network output cable.
Gain control is performed by 10dB switchable and 0-10dB variable attenuators in each input. This gives a total range of 20dB level control for each input. V51-204 is housed in a diecast chassis for rigidity and extra interference immunity. The built in SMPS power supply is designed for stability, cool running and long life.
V51-204 is ideal in small, medium and large MATV systems and as a launch amplifier in IRS installations.
