Dish Networks, Dish Pro technology changed the way their satellite dish LNBs transfer the satellite channels from the dish to the receiver inside the home. Not all Dish Network receivers are able to work with Dish Pro LNBs (DP LNB). The DP Twin LNB/Switch combo units look very close to the original LNB combo unit, which are now called Legacy Twin 500s.
With the DP LNBs came a new switch. The DP-34 switch. Using the Dish Pro technology, they were able to use a single switch for many applications. Several DP34 switches can be linked in a series to provide satellite signal to as many receivers as needed.The only visual cue is the Dish Pro Logo. It is important to know that DP LNBs will not work on legacy receivers with out an adapter. See our Dish Network receiver page for more about DP compatible receivers

The only disadvantage to Dish Pro technology is the use of higher frequencies. The high frequency used between the dish and receiver raised from 1450 MHz to 2250 Mhz. This higher frequency increased the minimum coax cable requirements. With legacy systems, an installer could use much of the existing cable found in older homes. Dish Pro changed that. For proper performance, it is critical that newer RG-6 coax cable be used for all Dish Pro installations. Most existing RG-6 will work, but some will not. Another important part is the method used for cable installation. Metal staples will often pinch the cable and dramatically reduce the signal quality. See the Consumer Awareness Project for proper cable installation methods.
Dish Pro technology made it simpler for technicians to install more then one receiver and it allowed for one switch to be used in several applications. But for the new dual tuner receivers coming on to the market, you still needed to have two coax cables installed from the dish to the receiver location. Each tuner acts like a separator receiver and needed its own dedicated cable.
Dish Network Dual tuner receivers can operate using one coax to provide signle, if the LNB is a DishPro Plus (DPP) LNB. More about Dish Pro Plus LNB's at the end of this page.
In some cases, installers need to install a single dish to receive a satellite. Due to no line-of-sight issues, it may be required to install one dish for 119 and another for 110, with each positioned to receive the desired satellite.
Single Dish Pro LNB With Dual Output
Customers who need to receive satellite 61.5, or 148, cannot to use a single multi-satellite dish such as the Dish 500, Dish 1000, or the Dish 1000.1. To avoid using legacy LNBS and returning to the SW-64, or other legacy switches, a Dual DP LNB is used. The term dual does not mean it receives two satellites, those LNB's are called twins, or quads. The term dual refers to the fact that is has dual outputs. This is a common mistake even among professional installers.
To increase channel capacity for the addition of more local channels and international channels. Dish Network developed the Super Dish. The Super Dish receives satellite signals from the 119 and 110 satellite locations as well as a third satellite. There are two versions of the Super Dish. The 105 Super Dish receives programming from a satellite at 105 and 110/119. The 121 Super Dish receives programming from 110/119 and 121.
The Super Dish version you use depends on the programming you desire. Not everyone uses a Super Dish.

DishPro Plus LNB
In the fall of 2004, Dish Network released its latest innovation. DishPro Plus. DishPro Plus technology allowed one coax cable to carry the satellite signal requirements for two receivers or one dual tuner satellite receiver. This single cable solution solved many problems with installations of the newer DISH 322, DISH Player 522, DISH Player 922 and DISH 942 receivers. All dual tuner units using a DPP single cable installation require the use of DPP Separator to seperate and isolate the two satellite signals.
Another nice feature of DishPro Plus is it will work with legacy receivers as long there is at least one other DP compatible receiver in the system. The DPP Twin LNB (right) has three coax connections. The two on the left connect to receivers or DPP distribution switches (DPP44). The single connection on the right connects to another DP single satellite LNB for reception of 61.5, 148 or 129. The DPP Twin LNB is the standard LNB for the DISH 1000.
