I understand the the LNA gets it power from a DC voltage that is transmitted down the line. My questions: For the DC voltage on the cable, how much is required and how much is the max? The receiver typically puts either 13, or 18 volts onto the coax, depending on whether it wishes to receive the lefthand or righthand circular polarizations. There's often some voltage drop between the receiver and the LNA/LNB. What is the IF down converter frequency? There's no single downconverter frequency. The system uses a low-noise block converter, which downconverts a whole range of frequencies simultaneously. I believe you'll find the downconverted signals located between 950 and 1450 MHz, if you aim the dish at a DirecTV satellite. The block converter is designed so that its usual outputs don't fall below 900 MHz - this allows a single coax to carry both the downconverted satellite signals, and VHF/UHF television signals via a diplexer. Can I use my FRG-9600 which has continuous coverage from 60 to 934 MHz as an variable IF to decode voice data? I don't know whether the block converter will output frequencies that low... they're below its normal output operating range. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
