multi feed ku

[gabshere]

well for the guys that have multi feeds for ku on on 1 dish...... my hat is off to ya.... lol i only got to work on it about 1 1/2 hours but failed to locate the next satellite over ( got 97 trying to get 101 so i need more work...... main reason was i was hunting blind and also i hook up the receiver wrong lol ... well it was my first time using a traxis 3500 ....... so i also had to get a feel for using that receiver to tune with..... plan on setting up two more stationary dishes tomorrow both are 1 meter primestars and one i plan on doing some c band testing. and the other will also be a multi feed tester.

ok post me some basic tips for finding the feed next over ( for multifeeds)
the dish i'm currently using is a primestar its 40 X 30 inches (84E)
the dish is centered on 97W.

101 the lnb should be mounted on the right side (if looking at the dish)?

 

[Mr Tony]

correct

When working with multiple LNB's they go backwards on the dish compared to their actual location due to the reflection off the dish

Case in point is the below picture...the main LNB (the farther one away) is at G10 (123W) and the closer one is at 119...

In the clarke belt the 119 LNB would be farther away but since we are working with multiple LNB's, they go opposite

 

[Mr Tony]

or in the case of the T90...sure they are aimed at the 2nd reflector but the setup is the same

closest is 119...farthest is 72

but in the clarke belt they are opposite (72 would be the closest)

An example of MJFlash's math to find location for multiple LNBs is well documented in LinuxMan's thread on his 123/129 Primestar setup.
Get your focal length, and we can do the same for you.

Below is a photo when I had 97 and 101 on the same dish. As in Iceberg's photo, to get satellites 4 degrees apart one LNB (101) had to be slightly behind the other LNB (which then partially blocks it causing some signal reduction). I remember it as being a pain to aim and get the highest possible signal (much tweaking). Due to the larger number of transponders on G25 (97), you don't want to put the 101 LNB in front of 97! Good luck.

Iceberg that is an amazing picture lol. Are you sure some kind of permit isn't required to own that many lnbfs? One question I've wanted to ask about these toroidal things is--Wouldnt it be cheaper to just buy one lnb and a motor, for what all those lnbfs cost? Or is it just because its a cool dish?

 

[gabshere]

instant channel change ( no waiting on motors) and plus you can add you subscription dish to this (toroidal) so it cuts down on the # of dishes plus if you motor over to g10 you can't have someone else watch a sub over at 119 or say your pvr is set to record a game over at amc3 .... so there are several advantages to having a toroidal... i would love one but i'm pacing myself you know with the addiction and all

Just to add to what George said, I also use 4x4 Multi-Switches (so you need dual lnbf's) so the Torodial can be used with multiple receivers (up tp 4), and like George says, any receiver can watch any of the lnbf's.

Those are good answers, things I didn't think about. I haven't seen one of those dishes anywhere yet, but they seem to be gaining momentum.

 

[Mr Tony]

original reason was to combine my Dish subscription, StarChoice subscription and a couple KU LNB's onto one dish (which eliminated 4 dishes at the time)

Also as noted above, hook up some 4x4 multiswitches and you can have multiple receivers on different satellites
(works really good during sports seasons)

But the main drawbacks are only 40 degree spread and its 3 degree spacing between LNB's so you have to go like
85,89,93,97 or 83,87,91,95 etc

I use a cheap signal meter, hold the LNB by hand and hunt for the best signal. Be aware that it maybe lower or higher than 97. Once you feel you are in the right location, mount the LNB firm and do a scan.

 

[ftarock]

it depends on your needs. If you only watch channels on 1 sat at a time, having motorized dish is a better choice because it will get you best signal from the sats.
If you (and your family members) watch channels from more than 1 sats, Toroidal is a better choice.
all depends on what you needs are.
In terms of costing, Toroidal is a bit more expensive than diseqc motoro/dish combo. Good thing is it will last darn longer than the diseqc motor...but a good motor such as Stab will have a lifespan more than 3 years.
I have been using a STab for more than 3 years, still going strong...no problem at all.

where can I pick up one of these bad boys... If I can add instant channel change to this set up... the wife will let me play more with FTA

Try "Eye in the Sky", for a T90 = 196.00 shipped

 

[airgator96]

anyway to add this to my current system without buying a whole new sat?

Find a neighbor that's willing to put one up and then talk them in to letting you run coax lines over to your house...

A long time ago, when I was still a young fool, and wifi was a new technology, I tried to talk a neighbor at an apartment in to splitting cable internet charges with me and shooting wifi signals down the outside of apartment walls... It never worked well, and we only had the equipment for less than 24 hours before returning it to the store we bought it from... be careful when trying do similar endeavors.

I thought that any self-respecting FTAer had two T-90's...
One for 85,89,93,97 . . .
and the other for 83,87,91,95 . . .


Also, didn't JerryT post how to get some bandstacked LNBs 2º apart on the T90?

 

[Mr Tony]

nah...dont need two of them. Honestly from 103-123 there isnt much on those satellites unless you have a subscription to Dish or StarChoice. 119/123/129 can be easily obtained on a separate dish

 

[Anole]

Iceberg -
I remember when you were buiding that T-90 ...
Didn't you experiment with small LNBs, grinding down their sides, and other tricks?
Do you have recommendations on how to pack more LNBs into the short space?

 

[Mr Tony]

nope that wasn't me. I just was able to jam 2 LNB's next to each other for 91/93 & 72/74

But there are other ways
