UFM230 Modulo amplificatore RF e filtro per UHF, 230 MHz di banda(*).
L'UFM230 Lectrosonics sostituisce il UFM50. Ha 12 dB di guadagno selezionabile e una banda passante di 230 MHz per coprire i canali RF dal 21 al 29.
The UFM230 provides a unique solution for antenna systems requiring long cable runs or distribution to multiple receivers or locations. The amplifier in the unit provides 12 dB of gain without attenuation. Gains of 5 dB and 8 dB can also be selected using the supplied attenuators. The built-in filters provide a 230 MHz passband.
To determine the correct attenuator for a particular application, first determine the total dB loss due to connectors, splitters, cabling, etc. The above example illustrates a 4-way passive splitter (ZFSC41) with 6 db loss and a coax cable (ARG15) with 2 db loss for a total loss of 8 dB. Therefore, you need 8 dB of gain in the UF230 (UFM50).
The example below show the UFM230 with a long coaxial cable (ARG100) connected to a receiver or multi-coupler. The cable presents 4.6 dB of loss, which can be rounded off to a required gain of 5 dB. A UFM230 configured for 5 dB of gain will offset the cable loss.
