The Difference?

[0bn0xi0us]

Sorry Newbie question here, what is the difference between the Dish Pro LNB and a Regular LNB?

Thanks

Dishpro only uses vertical tp's, 13 volts. Takes the horizontal tp's (18 volts) converts them to higher frequencies and and become vertical, 13 volts. Actually vertical is the wrong term since these are circular polarity, but our receivers show them as being horizontal or vertical, but are actually left hand or right hand polarity.
The advantage with DP is you can have a longer cable run.

The down side of dpp lnbs is that they require more power - certain receivers are problematic with them . On the positive side they have an internal switch ( based on diseqc) which eliminates the need for an external one , also , depending on models , one can connect up to 4 receivers, receive 2 sats with 1 lnb 110/110 or 82/91,or add input from a secondary dish .

Dish Pro LNB's (big DP logo on them) do not use any voltage to switch the transponder polaritys, they are band stacked, this is done inside the LNB, this means that all the "R" polarity transponders are in a 950 to 1450 MHz band, then there is a 500 MHz guard band, then follows all the "L" polarity transponders, they are in the 1655 to 2150 MHz band.

To properly use these types of LNB's your coax must be rated to 2.5 GHz or better, and using good RG-6 quad coax you can run out to 200 feet.

Some FTA receivers use an "OCS-DP" setting to use these types of LNB's, others use "Dish"

A regular LNB (sometimes called a "Legacy") uses +13 and +18 volts to switch the transponder polarity's, if they are Dish legacy LNB's then they are old.

Other "regular" LNB's can also be the linear type, they are used for the true FTA satellites in the 11.6 to 12.2 Ku band.

Here is a very useful DishPro document that will explain DishPro:
