    i went out and bought a digital satellite finder etc but its all the same.
    the main question is the dish toooooo small for perth c band, mainly want the asian channels, thaicom 5 etc
    thanks in advance for any help
    If you are getting 70% signal strength, that's generally fine.

    Poor signal quality with good signal strength is usually incorrect LNB SKEW.

    so you think a 2.1 meter dish is ok ?
    i can move the dish 180 degrees and the signal etc stays the same, doesn't rise or fall.
    i would have thought something would move up or down when i go between satillites
    very confusing

    Signal shouldn't stay the same when you move the dish, so you definitely have something wrong.

    Perhaps start with ALL information about your setup.... eg: what decoder you are using, what transponder frequencies etc you have programmed into it, the LO frequency of the LNB and do you have it correctly programmed into the decoder for EVERY satellite.

    Is the dish a fixed position, or is it motorised?

    What procedure have you followed to correctly align the dish/LNB?

    We need lots more info about your setup to be able to help.

    G'Day Cobber,
    From what you say, it would seem that you do not have the vaguest idea of setting up a Satellite dish.
    What make and model of decoder are you using?
    What is the Local Oscillator of your LNB?
    You need to point your dish quite accurately for each Satellite.
    Satellite information for our region is available here:-


    The relevant Pointing information, Azimuth, Elevation and Skew, as well as a ground line of sight for each Satellite, is found here:-



    Feel free to ask if you need further assistance.
    Kindest Regards, " The Druid ".

    Positioner EZ 2800 :

    its mounted on a 3 meter pole thats level, and pointing due north (per dishpointer.com)
    i moved it to asiasat3 and had elevation to 51 degress and pointing close to where dishpoint says
    the dish is setup as per instructions and measured for alinement and pointing directly to the centre of the dish and the f/d to 38
    entred the lmb freq to 05150, tp freq to 3706, h and symbol to 6000.
    came up with 79% signal and 4% quality.
    if i move the dish in any direction nothing changes

    So true, thought it would be easy to setup, done a bit of reading etc and followed all the instructions
    tried different satellites with the imformation on lyngsat.com but can't pick up a thing
    even went out and bought a 3.5" LCD Digital Satellite Finder Fr Sat Dish Receiver
    but got the same results
    must be something simple i'm doing wrong
    the tech here wants $150 per hour and said it will take 3 hours to aline the satellite

    Sounds like you haven't aligned the dish correctly, for starters.

    You need to do all the alignments before attempting to use a positioner/actuator.

    If you have the dish correctly aligned, you should get peaks of signal with each satellite it moves past as you move the dish across the clarke belt.

    Once you have the alignment/tracking correctly set up, then you can fit the actuator to drive the dish movement.

    If you are just slightly out with with the alignment on any axis, the dish will not track the clarke belt and you are unlikely to find any satellites.

    When you say you got 79% signal & 4% quality on asiasat3 (asiasat3s I assume) was that on the LCD sat finder, the decoder, both?... If they gave different readings, what were they?

    The dishpointer settings are appoximate only.... you need to fine-tune ANY and ALL dish alignment settings.

    Even with specialised, accurate instrumentation (eg: spectrum analyser) it can indeed take several hours for a professional/experienced installer to get every adjustment perfect for a motorised C-Band system.

    Also, apart from incorrect LNB SKEW, there is a possibility you have a faulty cable/connection or a faulty LNB.

    G'Day Cobber,
    Have a good read here. Should help you understand why a competent Installer can charge so much. You too can do the same, but may take you longer.

    Wow you have done all the hard work mounting the pole and fitting the dish and he wants to charge you 3 hours at $150 ph?

    I need to get back into installing sat gear.

    What i would do.....
    Assuming your elevation and declination angles are correctly set on the polar mount.

    Through the actuator, turn the dish to the west till the dish is at the correct look angle for asiasat 2 or 3.

    Undo the polarmount to pole locking bolts and turn the dish till you have a signal lock.

    Improve it by turning the LNB skew.

    My guess is your pointing to magnetic north instead of true north.

    Just my beginners mistakes suggestion.

    thanks i'll give it all a try in the weekend, i've decided i want to learn how to do it all, I'm part of a large asian community here (wifes Thai) and they all waiting to see how it works.
    my company is such that it would be good to branch out and install a few dishes and aerials etc
    give this wally over here a bit of compition

    If you plan to do it semi/professionally, you'll need a professional signal meter/spectrum analyser.
