how hard is it to get a satelite dish installed? is it possible to do it myself or do i HAVE to get someone to do it? the physical part is not the problem, you have to align it or something, is that a matter of keep moving it till i have signal or what? anyone?

You will not align the dish without some form of signal strength indication device. Do the physical installation an point the disc towards the North East (azimuth = 50 deg) at an elevation of approx. 55 deg from the horizon. That is a good start.
You can get these mobile dish alignment thingies from good caravan shop. It's a small device that plug into the LNB and a socket for an earpiece. You now "listen" to the signal strength to locate the PAS7 Sat. I think the higher the pitch the stronger the signal.
The manual that came with this device was rather criptic but I did manage to get a good signal within a few minutes of sukkeling.
The manual also contains a skymap of approximate dish azimuth and Sat elevation depending on your location within SA.

assumption 1: you have one of those devices?
assumption 2: you live in gauteng?
assumption 3: you know how it works better than me
request : can i buy you a case of beer?
I helped a friend install his dish. Took my small b/w tv and decoder up onto the roof, and used the decoder's signal strength meter to get the best signal. We got it tuned within a few minutes.
Squeezing the the last few pertentage points of signal quality by aligning the dish by hand is the most difficult as when you try to fasten the dish it disaligns slightly causing you to lose a bit of signal. We eventually got 90% signal quality out of a 60cm dish in the Cape Town area. Not bad I think as mine was "professionally" installed and I get 80%...

okay now sorry a few questions...
how long after you point it in the rigth direction will it appear on the screen as you are getting somewhere?
i mean i will first attempt to hold the dish on my patio and see if i get a signal. then mount it on the wall if i came right. but cant sit and point in all directions the whole day and not know if i'm even doing it right.
The dstv signal meter updates quite fast. If you turn the dish about 3 degrees per second, you should "catch" the right azimuth angle quickly. Remember to look at the signal quality percentage, not the signal strength.
What we did was install the dish on its pole on the chimney, and first fixed the elevation angle at around 55 degrees. Then it was easy to turn the pole and find the right azimuth angle. Once the correct azimuth angle is found, you can fasten the pole so that it doesn't turn sideways and then just fidget with the elevation angle again slightly to fine tune.
Don't be satisfied with less than 80% signal quality, the less your signal the more likely your picture will break up during a thunderstorm.
I wouldn't just hold it loose like you suggest. You can easily miss the correct angle I would think.

i think i will put it on its pole in the ground to start with. then move it like you say. i will look at neighbours one to at least see what direction to point the thing. haha.
what do you call that thing that you get from the caravan shop? any idea?

The method that ajax describes will work. When I did the install we still had the old software with the slow bargraph display. The new software does give a faster response on signal quality that does make it possible to align with a TV and decoder on the roof.
Fix the dish elevation at 55 deg. I think most decoders have a deg scale on the side, that is punced into the metal frame, to get you going.
The azimuth is about NE (45-55 deg from North).
I saw the unit for sale somewhere but for the life of me can;t remember. Try maybe Midas or Builders Warehouse. I think this unit is quite expensive though...

OK have a look at Ellies:

They call it a digital satellite seeker. It's part of a Caravan Kit though. Sure you can get it as a separate item.

shot. you guys help a lot i must say.
i really appreciate it. lemme call ellies... (if it cost more than R150 i may as well get someone to come install the thing hehe)

okay well the seeker alone is R299 from them. maby i can start my own business and pay it off. LOL

You did mention a case of beer! lol :D
What you can do: Instead of using a TV on the roof, use a video camera with a LCD display just to see the signal strength. LNB to decoder and decoder S-video output to Camcorder video input...just an idea!

lol i sometimes wonder about us humans. instead of paying R400, we are prepared to cart our whole tv and decoder and a lead up onto the roof and sit and aim hopelessly with a dish into the sky hoping something out in space will get a connection with your satelite dish....
well today after work my video camera and decoder will be on the roof... so if you see anybody with all their electronics and a campmaster chair sitting on the roof, throw me a beer hey!!

You could alway just get a friend to shout from your lounge, that worked for me when I set mine up and I have 60% strength and 86% quality in the Table View area.

lol i told my wife she's gonna have to do that. but she doesnt seem to keen on the idea. it may take like an hour of batteling to even get half a % of signal. will try and get back to you people tomorrow! :D

A friend of mine did it for me.
1. Get a tweeter tuner at Makro or Game. Little thingymabob that costs around R100 that indicates allignement. It is red with a little earplug. It is mainly used to tune portable dishes.
2. Make sure you mount your bracket on the right side of the house. Look at neighbours for a clue.
3. Buy the dish from a dealer or wherever you can that suits your pocket.
4. Remember that PVR requires a dual LNB. Invest in one from the start. Only costs about R600.
5. Wiring and grounding is important AFAIK. Obviously wiring correctly will make a huge difference
6. and when installing PVR keeping cables (from decoder to TVs) as short as possible is better. Less interference allows for better remote control functionality when using the remote blaster that signals through the coax.
I am sure other peeps can add more...

grounding? the dish? the dishmust be grounded?

The LNB and bracket should be earthed. Buy a 1 m grounding rod and drive it into the ground close to the mounting position and connect with a good quality copper wire. Welding cable works best.
I tried the "person shouting form the lounge giving info about signal strength" trick but it ended in a massive argument ending just before one makes the decision to bring in Police assistance and classify the event as domestic violence....:D
Anyway, you still offering the case of beer?

The little gadget to get signal strength definitely works. When moving the dish, it must be in small increments, with about 2-4 seconds before moving it again. With compass and/or GPS, we normally get it set up (one of the portable dishes) in about 5-10 minutes to watch rugby in the bush :D

how essential is this to get a signal?
i moved that freakin dish last night in all directions didnt even get 1 % nevermind 80% or 90%

defnitaly. anybody interested in installing my dish for a case of beer???

Earthing the dish doesn't affect the signal quality or dish performance but it does give you some peace of mind when the thunder clouds roll in. Earthing is especially important if the dish is a prominent feature of the house outline.
If the dish is somewhat protected by the roof or house structure, it's not that important.
I'm not sure of building regulations require the dish to be earthed.

okay thats what i wanted to know. i am still trying to get the freaking thing to get a signal. once i got that right i will start earthing it and so on :)

Hey Albert, I presume you installed the LNB correctly on the arm - remember if you take the cap off, that little metal thingie should be at a certain angle else it will not work. What they call that again, I did this so long ago can't remember.

well the dish comes from a previous installation and that cap thingy hasnt been off so i dont see why that wouldnt work....
i moved that freakin dish last night in all directions didnt even get 1 % nevermind 80% or 90%
Did you make sure that there was nothing in the way, even a small tree branch can screw you around.

well i will try again tonight. does it have to be a certain height off the ground? i was putting it on a little table in the middle of my lawn?

The height shouldn't be a problem, but the thing is if you are out by just a few degrees on elevation or azimuth you will get nothing. If it is a 90 cm dish, the angle is even more important as the dish is more directive than the 60 cm ones.
Maybe you could borrow one of those portable dishes from a caravan shop and play around with that one first. They are smaller and hence don't need such pinpoint accuracy as the larger ones although they will give a lower signal strength.

hi wondering if anyone can help me. i bought a dstv elsat 60cm dish kit. set it up on the chimney. got the cable, ran it through the roof to my decoder. now i also bought a satellite finder with earpiece. so i connect it up and move my dish around until i get the loudest pitch possible. but i am still picking up nothing on my decoder when it says searching for signal with bouquets and tv services etc. shouldnt i atleast be picking up something?

Ok just reporting
We had a thunderstorm and some real bad wind 2 days ago, woke to find dish on the ground, so went about trying to set it up again without luck.
I searched the net and found this tread, and noted the post "check the signal quality, not strength"
so went and tried again, had a support crew shouting the percentage while turning it, so found it real easy, took only about 2 min,
got 96% quality and 72% strength now :cool:

... or just look at a neighbours dish and guess! :p

Further minute improvements can be had by moving the LNB closer or further away from the dish in its bracket.
