    Default Boosting Satelltie Signal from dish to STU

    Hi there,

    hoping someone could pls help me out. I am in Melbourne Australia and currently have a 2.4 meter fixed dish pointed at Telstar 10 to pick up FTA channels. I am getting RIK and ERT. ERT is coming in ok however RIK keeps loosing signal and cutting out bacause signal strength is is not strong enough I have trying rehoning the dish to no avail still same problem. Was wondering if there was some sort of satellite signal booster/amplifier i could get to connect between dish and stu to get better signal amplification . If so could someone pls advise me of what to get name brand etc.... and where i could get it from .

    Any help you can provide would be greatly appreciated

    thanking you in advance mcmuzzy

    yes you can get an inline amp but its for making up loss with long cable runs only (20m and over)

    The only way your getting to better signal is if you get a bigger dish

    Only way to boost your signal is get a bigger dish!

    Before you use a in line signal booster, check your connections, dish point, LNB skew and focal point.

    Ive run some pretty long runs with quality Rg6 and never needed one fitted.

    Remember one thing, when using a inline amp, not only will the signal be amplified but also any interference too.

    thx for the advise guys i really appreciate it. I understand that it will also amplify noise as well as signal . I saw on ebay i can pick up an Inline Satellite Signal Amplifier Booster 20dB gain and one that is 30db gain. which one you would you reccommend or should i look for more gain ??
    Also what MHz Range should i be looking at as far as Inline Satellite Signal Amplifier Booster goes for boosting signal from Telstar 10

    thankyou once again .

    thnx again .

    You seem to have missed the point of the previous replies.
    An in line amplifier does not increase the signal to noise ratio. If anything it makes it worse.
    You must increase your signal at the dish.
    Bigger dish / fine tuning focal point, skew, azimuth, elevation and check your line of sight to the Satellite for obstructions.

    once up on the roof what is the best way to fine tune focal point, skew and azimuth will i need any special equipment or just take my stu up on the roof and connect it to lnb with small screen and check it that way

    this is often the best way. Once you've got lock it's best to refine the signal by peaking the LNB skew, then going up, and down until it's best signal.

    usual story, the meters will peak, then drop off, just fiddle till you get the best signal. Also (if you STB shows it), you want a low BER too (error rate)

    Talking Optimising a C Band Dish.

    G'Day Cobber,
    Quite sophisticated Spectrum Analyzer, etc. would be ideal, but not entirely necessary.
    Do as you have suggested, making each adjustment in small increments.
    One trick is to gently push/pull the dish in azimuth and elevation to see which way to adjust. Focal point is in/out in the holder and fine adjustment of the rings. Skew is rotation in the holder. There are two points, 180 degrees apart for max. Use the one where the lead is down to minimise water ingress.
    You should be pleasantly surprised what you will gain by careful tweaking.
    Kindest Regards, " The Druid ".

    Some transponders are (as you've discovered) weaker than others on Telstar 10. Fine-tuning dish alignment and LNB settings will give you the best possible result with the dish you have, but ultimately, you'll need to increase the dish size to 3m+ for reliable reception.

    If it's a mesh dish, replacing it with a solid dish of the same size would also provide extra gain, similar to that of a 3m mesh dish.

    ahhh, never tought about it! Thanks for that info.
    Bit off topic now (curiosity):
    is it possible to link few dishes to gain signal?, sort of like multiple telescopes in astronomy..?

    Cheers

    I would imagine so. Distance apart and phasing. Probably need some very sophisticated equipment and plenty of patience I have no doubt.

    if it would be not to complicated/expensive than that could be a good solution for pple who can't install big dishes for whatever reason.

    If your already getting as 'Good as it Gets' on a fine day, the next weather pattern between you and the satelitte can wipe you out.

    This 'Multiple Dish' concept was discussed in depth in the old Austech Forums and at the time there were those who really knew their subject (engineer level) and it soon became apparent how complex that system is.
    Like the Very Large Arrays (VLS's) used in Radio Astronomy, the dishes need to be placed a little more apart than the average surburban backyard allows.
    Then there's the 'coupling', either by a Wave Guide or cable or Microwave.
    Then the receivers, Cyrogenicaly cooled, Minus whatever !!!!!
    Nothing the average DSE PowerBarn doesnt have on the shelves.(As If)
    Most of what they said went right over my head but it was damned interesting tho.
    Electronics Australia (miss that magazine) did some articles in simple langauge that supplemented those postings.
    So, a $100 Million or so later your up and running, untill they either go off the air or encrypt the signal !!!

    hehe... too complicated/expensive! Thanks for that input.
