I got a Viewsat Ultra, and I'd like to go for a two-dish setup to grab BEV/DN. I intend to buy 2 Dish 500 dishes, but am totally confused when it comes to the LNB's. Part of that is typical dual/twin confusion (still havent got that totally figured out) and part of it is just people on ebay not being clear about what they're selling.
Anyway, I'd like to set up both dishes with the option of hooking up another reciever at a later date in the bedroom. What I need to know is what would be the easiest way to set something like this up? What LNBF's would I want to have on both dishes? I would prefer to use something like 2 SW21 switches rather than messing with power inverters and all the risk to equipment that comes with it.
I think what I need is the Dishpro Twin but I'm not sure. Any help would be appreciated. Thanks in advance. |
Thanks to Grasshopper fore this post.
Lnb And Switch Combinations Gives a good starting point as to what you will need
U need the right combo of LNB's and switches.
This document is directed to novice,and slightly experienced hobbyists.Its purpose is to help those in need of answers to basic switching setups;It is not directed to those involving 2 or3 types of LNB's to 5 receivers...you should already be blueprinted.
You must determine your setup and gear.Here we will try to get you started with the most efficient and reliable switches.
One
LNB to one receiver..............no switch needed
One
LNB to two receivers...............no switch needed(requires a DUAL output LNB)
Two LNB's to one receiver............This can be done with any one of the following; AB switch/2x1 diseqc/4x1 diseqc/22Khz switch/4x4 multiswitch
(1) A/B switch from wallyworld or Ratshack;works great,switches every time...you will need 2 cables run to switch. (NOTE! not recommended to switch with power on you could fry your
LNB or stb.....Randy)
(2) 2x1
Diseqc switch;works reasonably well;antennae settings must coincide with switch inputs.
(3) 4x1
Diseqc switch;Probably the most widely spread and unreliable switch on the market.Performance level is abysmal.Does NOT like 2 different types of LNB,long cable runs,water,humidity,or anything else.Best brand by far for a good price is Chieta,and Spaun for high end...better be for the money.
(4) 22Khz switch; Very reliable tone switch.Easily installed and reasonably priced.One line from each
LNB to switch,and one line out to receiver.Highly recommended.
(5) 4x4 multiswitch; Very versatile switch that requires dual LNB's.It can drive up to 4 receivers,and is 22Khz operated as well.These were around in the old D*V days and have an excellent track record and are highly recommended.
Two LNB's to two receivers..........This is where multiple switches is required in 3 of 4 examples.
(1) 2x1
Diseqc switch;2 required for this installation,as well as 2 dual LNB's.The outputs from each
LNB will go to a separate 2x1 switch,and from switch to receiver.
(2) 4x1
Diseqc switch;2 required for this installation,as well as 2 dual LNB's.The outputs from each
LNB will go to a separate 4x1 switch,and from switch to receiver.
(3) 22Khz switch; 2 required for this installation,as well as 2 dual LNB's.The outputs from each
LNB will go to a separate 22Khz switch,and from switch to receiver.
(4) 4x4 multiswitch; 1 required for this installation,as well as 2 dual LNB's.The outputs from
LNB #1 will go to Sat A inputs,and the outputs from
LNB #2 will got to Sat B inputs.Do not be concerned with the 18v and 13v allocation,as the switch "freezes" these voltages within the unit.Set 1 sat to 22Khz ON,and the other to OFF(in your settings).
This
Unit can drive up to 4 receivers.
Three LNB;s to one receiver...........As much as we hate to say so,the 4x1
Diseqc switch is the simplest(although not the most efficient) switch for this job.As the cost of these has dropped,so has the quality.
Four LNB's to one receiver..........Again,reluctantly,the 4x1
Diseqc is the simplest choice.
Two LNB's to three receivers..........4x4 multiswitch
Two LNB's to four receivers............4x4 multiswitch

1
LNB = 1 sat bird..but for ~~~~~~~~~~~ TV, most people want 2 satellites,the 110 and 119 birds reception on each receiver..
--------------------------------------------------------------------------------
LNBF
1. Legacy:
a. single: called single legacy, one output.
b. dual: called dual legacy, 2 outputs.
c.
twin : big fat
LNBF , 2 outputs, has 2 SW21 switch built-in. (sw21 is not for FTA)
d. quad: big fat
LNBF , 4 outputs, has 4 SW 21 switch built-in. (sw21 is not for FTA)
2: DishPro
a. single: called single DishPro, one ouput.
b. dual: called dual DishPro, 2 outputs.
c.
twin : big fat
LNBF , 2 outputs, has 2 independent
Diseqc switch built-in (FTA-yes)
d. quad: big fat
LNBF , 4 outputs, has 4 independent
Diseqc switch built-in (FTA yes)
Dish Pro
twin LNB gets both the 110 and 119 on 2 receivers..and no switches needed...
Dish pro LNB's cannot use legacy channel lists...need DP channel lists
sw21 switch are used with ~~~~~~~ receivers
disque switch is used with FTA receivers
--------------------------------------------------------------------------------
DUAL
LNB is for 1 satellite signal (example 110) and 2 receivers...
twin LNB aka fatboy/fathead is for 2 satellites ( Example..110 and 119) AND 2 receivers .. there is much confusion about DUAL vs
twin LNB's
--------------------------------------------------------------------------------
For all who wish to use Dishpro lnbfs
Dishpro lnbfs are erronously being reported as not usable with Fta receivers because of internal switch. this is not true. You can use them with no additional switch needed. The only time you will need to use an additional switch is when adding a second dish to your system. Pro lnbfs have a built in
Diseqc switch not a sw21 as the legacy
twin has. You can easily identify pro lnbfs by a large black D/P label. All that is needed to use this
LNBF is to connect 1 cable from
LNBF to rcver. Each output on this
LNBF carries both 110 and 119 signals. The different outs are for connecting additional rcvrs. Load a modified dishpro channel list or modify your own list by using Gtools. To do this subtract all horiz. transps. from 25600. enter result as your new transp freq and change to vertical. IE. on sat 119 transp 6 is 12297h. doing the subtraction, you get 13303. So change transp 6 to 13303 and change h to v. Now you have 13303v And will be received dy dishpro lnbf's. To get a bit technical, the dishpro's use an oscilator that runs at 25600mhz. this is mixed with the horizontal transp freqs and new freqs are generated. If you should wish to add additional dishes to receive a third and even a fourth sat you must add a external 4x1
Diseqc switch. you must feed both port 1 and 2 with both(or in case of quad,2 )outputs. you can then add a third dish to port 3 and even a fourth to port 4. I hope this clears up the confusion.

DishPro
twin or QUAD LNBs have an internal DiSEq switch and use an LO of 11250
For FTA receivers the switch settings are:
DiSEq1(or A) for 119(echo7)
DiSEq2(or B) for 110(echo6,
Use no external switches unless you are adding a 3rd satellite/
LNB to your system. You will also need to use a DP channel list OR manually edit the H transponders
Dish types and uses.. Dish 300
Single slot 18" round
DBS dish that can pick up programming from one
DBS satellite location at a time.
DBS locations for Dish are 61.5°, 110°, 119°, 129°, 148° and (not used) 157°.
Dish 500
A two slot 18" x 20"
DBS dish designed to pick up 110° and 119° simultaneously. However it can be used to pick up 119° and 129° or just one satellite location like 61.5° or 148°.
Dish 1000
A three slot
DBS dish designed to pick up 110°, 119° and 129° simultaneously. This dish can be used to pick up 129° and 148° simultaneously.
Dish 1000.2
Slightly larger than a Dish 1000, its integrated head
Unit has 3 LNBs (110°, 119° and 129°), an input for a 4th
LNB , and DP Plus switching to 3 receiver outputs.
Plus Dish 500+/1000+
Same as the Dish 1000 in function but about 5" larger and can pick up the 118.75°
FSS location. As a 500+ it picks up 110°, 118.75° and 119°. Adding an
LNB for 129° makes it a 1000+.
SuperDISH
105: Specifically designed to pick up 105°, 110° and 119°
121: Specifically designed to pick up 110°, 119° and 121°
Dish Size Mast Use Alternate
Dish 300 18" round 1-5/8" One
DBS slot
Dish 500 20"w x 22.5"h 1-5/8" 110° & 119° One
DBS slot,
119° & 129°
Dish 1000 23"w x 18"h 1-5/8" 110°, 119°, 129°
Dish 1000.2 25.9"w x 20.7"h 1-5/8" 110°, 119°, 129° Input for 4th slot
Plus Dish 30.9"w x 23.8"h 1-5/8" 110°, 118.75°, 119° Add 129°
SuperDISH 33.3"w x 24"h I: 2"II: 2-3/8" 105°, 110°, 119°..110°, 119°, 121°
Dish, LNB And Switch Info C/P
all,
There are lot of misinfo floating arround, so I take some time to do a summary of DN lnbf/switch.
LNBF
1. Legacy:
a. single: called single legacy, one output.
b. dual: called dual legacy, 2 outputs.
c.
twin : big fat
LNBF , 2 outputs, has 2 SW21 switch built-in...****nnot use with FTA
d. quad: big fat
LNBF , 4 outputs, has 4 SW 21 switch built-in.
2: DishPro...great for FTA and DP receivers
a. single: called single DishPro, one ouput.
b. dual: called dual DishPro, 2 outputs.
c.
twin : big fat
LNBF , 2 outputs, has 2 independent
Diseqc switch built-in
d. quad: big fat
LNBF , 4 outputs, has 4 independent
Diseqc switch built-in
Remember..
single LNB...receives ONLY 1 satellite signal and has 1 output to ONLY 1 receiver
Dual............ receives ONLY 1 satellite signal but has 2 outputs for 2 receivers
TWIN....has built in switches..receives 2 sats AND has 2 outputs for 2 receivers
Quad... same as
twin but has 4 outputs for 4 receivers
Many people get Dual and twin confused, so there are pics of each attached..they happen to be Dish Pro, but Legacy look similiar except for the DP logo..
Switch
1.
Diseqc : 2 versions: 1.0 and 2.0. People having problem with 2.0 version
a. 2 ways: 2 inputs, one output. Switch up to 2 lnbfs....OK for FTA
b. 4 ways: 4 inputs, one output. Switch up to 4 lnbfs....best for FTA
2. 22khz switch: 2 inputs, one output. Switch up to 2 lnbfs.
3. 0/12v switch: 2 inputs, one output. Switch up to 2 lnbfs. (Note: 0/12v switch needs to be installed close to the receiver, therefore 2 cables has be run into your house)
4. There is no such thing as
Diseqc 1.2 or 1.3 switch. The 1.2 and 1.3 (aka USALS) are for motorizing
Diseqc h-h mount.
5. DP34. 3 inputs, 4 outputs. Can be used to combine a 2nd (61W or 148W)dish with DP
twin or quad, so receiver will get signal from 3 sats.
Switch does not work well
1. SW21...not suggested with FTA's
2.
Diseqc 2.0 version (either 2 ways or 4 ways).
Dish 500
1. with 2 separate legacy single or dual lnbfs.
2. with legacy
twin or quads
LNBF , no good.
3. with DishPro
twin or quads
LNBF , good. Need to use modified transponder list.
Setup:
1. Dish 500 with legacy single/dual lnbfs: use with any working switch stated above to switch between lnbfs. 2nd or 3rd dish can be added using
Diseqc 4 ways.
2. Dish 500 with legacy twin/quads
LNBF : replace the
LNBF with single/dual lnbfs or DishPro twin/quads.
3. Dish 500 with DishPro twin/quads
LNBF : good, controlled by
Diseqc command using modified transponder list. 2nd dish can be added using DP34 switch.
