So, before I hook up my satellite to this, I keep hearing DC block or voltage block splitter. I'm thinking this would be a good thing to get in my collection before experimenting. Any links to example products?
To place the DVBT USB tuner inline between the receiver and the LNBF out at the dish, you will need a splitter capable of passing power from the STB to the LNBF, but block the voltage from reaching the DVBT USB dongle. The splitter should pass frequencies up to the top of the satellite IF range, so look for a top range of 2150Mhz.
An Example would be: http://www.solidsignal.com/pview.as...ase&utm_medium=organic&utm_source=google_base
If you only use the DVBT USB dongle on the loop-out port of the STB, no voltage is present on this port and no voltage blocking is necessary.
