    advice diameter dish and minimum 3 lNB's

    Dear

    Can someone give me some advise.

    I'have a dish with the name 'nuevo lifetime warranty', I measured the diameter, it's 75cm

    I'm thinking to get a new one.

    I live in Belgium.

    Can someone point me to the right direction?

    I have read a lot about satellites.

    I would like to receive at least 3 satellites: hotbird 13°, astra 1 19,2° and astra 3 23,5°

    If possible, also astra 2 28,2° and/or badr 26.00°

    first setup would be do receive all of the satellites, ( 5 satellites.). so let us first talk about what is needed for this setup.

    Because we live in a country with al lot of rain (winter , .. )I want to avoid using 23mm LNB's.

    I wan to use 40mm LNB, so I can receive a good quality signal.

    How big does my satellitedish has to be , if I want to use only 40MM LNB for eacht satellite signal I want to receive, as long as I don't have to use 23mm LNB's.

    Maybe 40mm LNB for astra 2 and badr is to big? But if the dish is large enough, maybe it's possible? because I think that how bigger the dish, how bigger the distance between the LNB's, correct?

    I don't need a motor, I just want 3to 5 LNB's on a multiholder.
    A simple triax dish (cheap) is enough for me. for LNB, i was thinking the inverto black premium 40mm (cheap and good quality)

    Can I manage to install the first setup on a (75cm, 80cm, 90cm, 100cm, 110 ) cm dish in Belgium? location is 50.891494,4.700217.

    I want a dish that is big enough to have enough signalreserve during rain and snow.

    Generally speaking, with a 120 cm dish your minimum distance between LNBs is 3 degrees, unless you use multiconnect (23 mm) LNBs.
    With regard to rain and snow, it all depends on their intensity: there's no dish diameter that can grant you a decent reception with pouring rain.

      the majority of fans watch satellite TV using satellite dish 90 cm, from the rain and snow will not help you larger diameter dishes, as the drops and the snow cover surface Converter, therefore, falls signal.

        Go for 120 CM Dish, but 26 E is slightly difficult for you. You can't do any thing against rain

          You have to think about the fact that with more than one LNB, they are not exactly in the focus of the dish and gain is not the same as with only one LNB, so a bigger one is always better...

            Hi mate

            In order to have good signal and avoid problems from rain,
            I suggest you to use 2 dishes of 120cm.
            1 for 19E + 13E and
            1 for 28.2E + 26E + 23.5E.

            Yes I know .... that the cost is a little high, but is a very good solution.
            For the second dish you have to use slim lnb's only (like alps).
            for astra and hotbird you can use everyng you want and of course you can add more lnb's to get many other satellites.

            Finally, I would like to make an other suggestion...
            Think about a motorized dish.
            The cost is the same , maybe you need less money, but you have more choices.

              Also consider a motorised option. Buying a motor would be cheaper than 4 or 5 lnb's and you'd have more open to you.
              Yes you have to wait for the motor to move to a different sat, but it's pretty fast.

                I would suggest you think about a Motor rather than a Multi Lnb set-up. I spent about 5 years with a 3 Lnb set-up on a 1 Mtr dish, it worked very well but when I fitted a motor I discovered a whole new world, It also may be a lot cheaper going for a motor.

                  I live also in Belgium

                  I would suggest a WaveFrontier T90 dish and 5 LNB's

                  for 13E + 19E and 23.5E you can use normal 40mm LNB's
                  for 26E + 28.2E you have to use 23mm LNB's (or mabe Smart Rocket Trs Single 40mm LNB's)
                  This way I would add 16E to receive
                  Also a suggestion EMP-Centauri DiSEqC switch S 8/1PCP-W2 (P.168-W) this have to be the V2 version not the older one!!!

                  I have no problem with rain or snow-clouds

                    That's definitely the best solution, though not the cheapest

                      Re: advice diameter dish and minimum 3 lNB's

                      Well, first of all, thanks al lot you all for your helping me out.

                      I was thinking to go for a motor but thaught maybe it wil be to much cost, and installation.

                      My other reason is also I want to learn to instal myself my dish, so it's a good way to learn.

                      They say that a motor is not always better? some advice to take that certain motor(name I don't know anymore). So before I want to start with motors, I need to do some preparations;

                      @ gianni253: so if the size of te dish wil not help if it's raining a lot, then I will take distance from a large dish. then MAX 90cm wil be ok.

                      .... with a 120 cm dish your minimum distance between LNBs is 3 degrees... . What do you mean with that? 26° and 28° is then not a problem to use for each 40mm LNB? but only if I use 120 cm dish? so it means I must use 23mm LNB.
                      I rather want to avoid these small LNBs as they are sensitive for raindrops.

                      So if I understood correct:

                      120cmm dish = 3 degrees distance -> 26° and 28,2° with 40mm LNB is possible.
                      90 cm dish = ? degrees distance -> badr , 26° and astra 2, 28,2° with 23mm LNB is possible, 40mm LNB not possible?
                      For the others (hotbird, astra 1 and 3) it's alway possible to use 40mm LNB(80-90cm dish)

                      and why do you use degrees (° )to measure distance? :-)

                      @rizwan

                      Why is 26° difficult? Because I'm from Belgium? A friend of me has it (I installed it for him), but he has only one LNB.

                      @herrr
                      so a bigger dish is better for better signal in case of more then one LNB? thanks for the confirmation.

                      @ kalpikos
                      I have to see if I can put 120cm dish but chance is small, let alone 2 dishes :-)

                      But if it's not possible at all to use 40mm LNB for 28,2° and 26° , then I will choose one of them. But 13, 19, 23 should have no problem with 40mm LNB's at all, even if I use a 78cm dish?

                        Motor is more expensive, hard to fine tune, and you have delay when zapping from a sat to another ...

                        Good choice, as far as it's enough for the weakest transponder you are willing to receive (take a look to the footprints to be sure)

                        "Min 3 degrees" means you can't receive 26° and 28° (difference here is 2°).
                        LNB should be overlapped ... that's why you should use "slim" LNBs

                        With smaller dishes the minimum angle is higher because the focal lenght is shorter. With 90 cm dish it could be 4°, i.e. 13° and 19.2° is possible (difference is 6.2°)

                        It's angular distance !

                          You will definitely struggle to pull in 26e unless you go for a very large dish.

                            Hello haramo,

                            I live near belgium and I can confirm a 75cm dish is big enough for 13°, 19,2° and 28,2° on one dish - with diseqc 1.0 (4in1) a cheap solution. Perhaps you can also use 5° as fourth sat on your dish.
                            19,2 and 23° is to close.
                            If you want to make God laugh, tell him your plans!

                              So if I hear this all, then I have to make my decision.

                              I will see for a max 90cm dish. Then I will install only 19.2, 23° and 13° , and I will experiment with an old LNB for 28 and/or 26°, I have twee slim LNB and one standard LNB.

                              the 19.2 and 23 are very important for me to have, but it was told that I could use 40mm LNB for both on my (old) dish of 75 cm, so 90cm will be no problem right?
