Hello to all,

 

I'm about to purchase some LNB's to feed four receiver at the same time.

But each receives must have it's own LNB that they have full control of.

 

The setup wil be as folow:

 

4x LNB's with 4x F-Connector outputs.

4x DiSEqC switches.

4x Sat-Receivers (single tuners)

 

What is the difference between Quad Switch LNB vs Quattro LNB ?

 

Can someone advice me which LNB that I have to buy.

 

Thanks in advance for you help!

I have found out that I need Quad LNB's for my purpose!

 

Quatro or Quattro LNB's are for big distribution systems like on an Apartment/Buldings etc...

Actually probably not...

They can be used for that purpose, but also for home use. As soon as you have four (indepedent...) tuners (in whatever amount of receivers, that is irrelevant) or more, it can be interesting to use a multiswitch-system (with quattro lnb's). With quad lnb's you'll never be able to connect more than four tuners, whilst using a multiswitch, you can connect whatever amount of tuners you'd like, it only depends on the switch. This already may be interesting starting from four tuners. I actually do have this setup and it doesn't have to be more expensive than quad lnb's. The multiswitch costs extra, but the lnb's themselves are much cheaper.

Aren't those multi-switches much more expensive?

 

I mean, if it's home use it might be better using Quad or Octo LNBs and simple, cheap multi-switches?

 

I have a T90, too + 16LNBs, 12 of which are Twin and 4 Quad, with Centauri 2 x 16in1 switches and 1 x 4in1 and it's not that expensive and all tuners are independent...

 

If I sell this one, now that I am moving again, I will buy Octo LNBs and connect each room separately, Twin and Single tuner recs and peace... :D I mean, Cantauri 16in1 are only around €40 nowadays...

Multiswitches are good if you want up to 4 satellites to 5 or more tuners. I have 13 quad LNBs on a T90 and one quad LNB on dish with actuator motor + polar mount, and four EMP Centauri 16:1 switch. If I wanted 14 LNBs with multiswitch for let's say 8 tuners, I would need 4 multiswitches and 8 spaun diseqc 1.1 switches. The cost would be very high.

They're a bit more expensive, but the LNB's are way cheaper.

It's down to simple maths and demand for quality of signal, so one sits down and calculates...

 

How many satellites do we want to watch and how may tuners do we need to feed?

 

What kind of loses have various (multi)switches?

 

LNBs - gain v. cost?

 

Do the rmaths...

Not only "maths... " For starters, if the minimum reception goes from 18 dB to 16 dB by inserting an extra switch, it's irrelevant....

 

Also, if you buy a whole array of quad lnb's, and want to add another tuner, you'll have to replace all lnb's. Not everybody would be keen on that.

You mean to say, after all it is down to maths... :D
