Dishes

Dish 300 Single

Legacy Dual Ouput LNBF and 18 inch round dish. Use to receive from 61.5 or 148 degree echostar. Can also add to a Dish 500 setup using Twin LNB and a DP34 multiswitch to distribute 101, 119, and 61.5 satellite. Some have Winegard printed on the dish face. Optimized for Dishnetwork, ExpressVU. One LNB allows two receivers to be connected. This original Dish Network dish design, used to receive programming from a single high powered DBS-band satellite, is now mostly in use by customers requiring the use of a second dish in order to receive local programming.

Dish 500 Dual Single LNBs

The first Dish 500 Dishes used two-single LNBs for a one receiver system. This Dish 500 with two Dish pro single LNB's will receive signals from Echostar 7 (110) and from Echostar 6,8 (119). A Dish 500 Dual installation may use DP (Dish Pro) LNB types or two Legacy LNB types. Either allows a receiver to get signal from both the 119 LNB and the 110 LNB. Dish network developed the SW-21 Switch for combing the signal from the two separate LNBs. Note that even with the dual DP LNBs the SW-21 switch is still required. The SW-21 Switch is a digitally controlled A/B switch.

Dish 500 Legacy and Pro

Made for Dish Network by Winegard with either Legacy Twin or Dish Pro (DP) Twin LNBs used to pickup the Echostar 110 and 119. The Pro Twin LNB features a built-in DP21 videopath multiswitch compatible with all newer "DishPro" receivers. Older units equipped with they legacy twin LNB, newer equipped with DishPro Plus twin LNB. Units may also be available with the old Legacy Quad, which still received from two satellites but allowed for a total of four receivers.

Dish Pro 500 Plus

Dish 500+ adds a third LNB. Receive from satellites 110°, 119° DBS-band and the 118.75 FSS Ku-band satellite. This dish replaces previous 500 models which could not do the 118.75 satellite.

• 20"x24" : 110°, 119°, 118.7°

Super Dish 105

Can receive from 3 satellites, replaces earlier Dish 500 which could only receive from 2. The 105 SuperDISH is pointed to receive signals from Dish Network satellites at 105, 110, and 119 degrees West. SuperDish was the first design by Dish Network to receive satellite programing from the core 110/119° DBS-band satellites and also programming from either the 105° or 121° FSS Ku-band satellites. Local programming for selected markets were originally broadcast using the FSS Ku-band satellites. Recently, Echostar has migrated many local markets to the new 118.75° satellite to allow most U.S. customers to receive it as well as nationwide high definition programming from a single dish. Currently, there remain a few selected local channel markets that require the use of a SuperDish to receive local channels. These markets will require a second dish if they wish to receive high definition programming.

Super Dish 121

Can receive from 3 satellites, replaces earlier Dish 500 which could only receive from 2. The 121 SuperDISH is pointed to receive signals from Dish Network satellites at 110, 119, and 121 degrees West. Appearance nearly the same as 105. Just like the 105 the 121 is a legacy dish.

Dish 1000

DISH 1000 legacy provided reception from the 110, 119 and 129. Replaced by Dish 1000.2.

• 20.5"x22.5" : 110°, 119°, 129°

Dish 1000.2

The Dish 1000.2 antenna gives you the advantage of receiving more programming (such as HD) using a single dish solution. Reception from 110, 119 and 129 and allowing 3 receivers. Can also add a second dish. International programming from 119 available. 3 outputs DISH Pro separators can be used to create up to six outputs from the dish. Compatible with DISH Pro single-orbital LNBFs or DISH Network bandstacked LNBFs, and DISH Pro Plus 44 switch.

• 23.8"x30.9" : 110°, 119°, 129°

Dish 1000 Plus

The DISH 1000+ supports reception from 4 satellites. Includes a DP Dual Band LNBF and two DP Dual LNBF. The DP dual band LNBF receives 118.7 and 119 while the 2 DP Single LNBFs receive 110 and 129. Install using a DPP 44 switch. Works with any Dish Pro or Pro Plus receiver from Dish Network. Primarily used to receive nationwide high definition programming, delivered form the 129° satellite. The elliptical Dish1000+ design replaces the Dish1000 design, which did not receive the 118.75 FSS Ku-band satellite.

Dish Parts and LNB Information

Legacy LNB Explained

Dish Network uses a general type of LNB called a circular feed lnb. All of the following DBS providers use specific types of circular LNBs: Dish Network, ExpressVu, and Direc TV. With these circular LNBs not all are compatible across the DBS providers. ExpressVu and Dish Network are compatible.

This term is in reference to LNB switching that is necessary for receivers connected to more than one LNB. Remember, to receive from more than one satellite, more than one LNB was needed. Dish 500 introduced a dual LNB system. The receiver needed a way to switch between one LNB and the other, depending on what satellite a particular channel resided on.

The Dish 500 required a 2 in 1 out switch(SW21), and the 4 in 2 out (SW42) switch for the receiver to receive from two satellites (119 and 110). Then Dish Network came up with the legacy Twin 500 and the legacy Quad. This LNB's incorporated two LNB and internal switches, eliminated the need for external switches.

The switching system had to be further improved to accommodate the connection of more than four total receivers. This improvement is the Dish Pro (DP) LNB. The Dish Pro (DP) LNB takes the odd and even transponders and brings them both to the receiver at the same time. The old voltage switching control of the legacy LNB polarity became obsolete. With the new system the signal could be split to multiple receivers. However, the new Dish Pro (DP) LNB consumes the use of a full 1000 MHz or 1 GHz of bandwidth. Coax cable which worked Ok for Legacy installations may not meet the needs of a DP installation.

The Dish Pro LNB's are typically denoted by the letters DP or DPP on the side of the LNB. The Dish Pro (DP) LNBs basically convert all horizontal frequencies to vertical so the lnb handles only one polarity. This is easier to separate signal with DP splitter. If the Dish Network receiver is a legacy receiver, it will not work with the modern DP LNBs.

Both Legacy LNB Dish 500 and Dish Pro 500 are designed to receive satellite transmissions from 119 and 110. Twin and Quad legacy LNBs will connect up to four receivers. They have the SW21 for each output. These LNBs are designed to work for old receivers for Bell ExpressVu & Dish network. For ExpressVu the satellites are Nimiq 91W & Nimiq 82W. The newer DP LNBs will not work with older receivers, as stated above. Newer receivers should have the letters DP right on the front or top to indicate compatibility with modern DP LNB dishes.

LNB Types Explained

Single LNB: This refers to an LNB designed to support only one satellite receiver. It cannot be split to support more than one receiver at a time. It may be pointed to a single satellite in space.

Dual LNB: This refers to an LNB designed to support two satellite receivers, or more with the addition of a multiswitch.

Legacy Twin: This unit is two circular LNB units inside one plastic housing with two outputs. The multiswitched signal combines both satellites 110 and 119 to be carried on a single cable. Two cables may be connected to this unit for two receivers. The Legacy Twin points to two satellites in space.

Legacy Quad: This unit also has two circular LNB units inside one plastic housing, except with four total outputs. The multiswitched signal combines both satellites to be carried on one cable, and up to four receivers may be connected, one cable per receiver. The Legacy Quad points to two satellites in space.

Legacy Dual: Two Single LNB units are mounted side by side, they are each in their own separate plastic housing. An external SW21 switch is needed to combine the signal from each LNB together. This is intended for supporting only one receiver. The SW21 is a legacy switch.

Dish Pro Twin:

Switches and the DisEqC

A dual has two coax connections. To allow a receiver to get signal from both the 119 LNB and the 110 LNB. Dish network developed the SW-21 Switch. The SW-21 Switch is a digitally controlled A/B switch. When the receiver want to tune to a channel on the 110 satellite, a digital signal using the DisEqC format was sent down the coax to the switch. Another signal was sent to switch back to 119.

Dish Network also came out with several additional switches for various applications. All the switches used the same DisEqC method. The SW-64 required an external power supply. The SW-64 was used to distribute signal from three satellites (usually 119, 110 and either 61.5 or 148) to as many as four receives. The 61.5 and 148 satellites are used for additional local channel channels, international programming and other niche market market programming.
