Satellite Dish

[dan20leeds]

Ok guys.

So I currently have an 80cm dish and have three lnbs, one on 16.0e, 19.2e and 28.2e, however I would like 13.0e but I cannot seem to quite pick up that signal?

Would my best option be to buy another dish that is bigger or is there another option? Please can someone advise me the difference between a motorised and fixed dish? Plus, what is the maxiumum number of lnbs I can have on one dish?

Regards

should be no problem if you are in leeds ?

4 to 6 lnb,s is achievable as seen in that multi sat thread by shady and I have 5 on my 80cm dish although the best ones are on 13e + 19e + 28e
getting 16e is hard due to the small separation between the lnb holders (its too crowded to get 13e + 16e + 19e with standard holders and standard 40mm lnb`s)

a motorised dish usually gives you better signals across all satellites compared to a fixed dish setup and even better using an inverto ultra black lnb too

Seems strange that I can only pick up 28.2 and 19.2 and 16.0 doesn't it? Is there any specific advice? Was just about to go and buy a new dish? Yes, I am in Leeds. Also the signal on the 19.2 is 95% but on the 16.0 and 19.2 it's around 83%, any ideas where I am going wrong? thanks

I can tell you now even with 19.2? east as prime focus satellite you will need the inverto multiconnect kit as the 3? spacing cannot be achieved with both 13? and 16? east both these positions require at least a 60cm as prime focus or above, I managed to squeeze in 23.5? east between 19.2? and 28.2? east but there was no room for the LNB holder to move just around a couple of mm but due to 23.5? east being as strong if not stronger than 28.2? east i got away with it being just off that slight amount.

But what i described above will not be the case with 13? and 16? east they both need to be spot on, you could try 16? east as Prime focus and jam 13? east as close as possible but it will still not be entirely spot on and with 16? east as prime then 28.2? east will suffer especially Eutelsat 28.5A bird its just not as powerful as the astra birds and presently $ly have used some transponder space on there as a stop gap until Astra 2G gets launched.

I would be more inclined to think you get 13e and 19e and 28e and cant get 16e myself

check the channels for each satellite position are actually correct, in other words make sure 16e really is 16e with albanian channels on it

check your last sentence too, doesnt make sense as I think you have your positions mixed up

[dan20leeds]

At the moment I am getting 84% on 28.2, 19.2 95% but 16.0 and 13.0 I am struggling to get signal. Why can't i achieve a higher than 84% signal on 28.2???

[ramjet]

the dish will tend to get the highest signal on the satellite it has been focussed on, in your case 19e
so you arent going to get a stronger signal on 28e unless you point the dish at it, and you should be ok with anything higher than 70% to 80% across the range
sometimes you can try too hard m8, you should be looking to get a good signal across all the 3 or 4 satellites, not 100% on all of them

That is a very vague question more information is needed to determine if the 84% signal is adequate and relates to the transponder and or channel you are receiving this figure from.

Also take into account the following factors the make and design of your dish the LNB type used even the quality of cable and also line of sight.

thanks. am I correct in thinking that i could add a motor to the fixed dish that i currently have? and if i added this motor i would be able to more easily change satellite? could someone give me a little brief bit of info thanks

yes you can, using a darkmotor or tm2600 technomate motor, T-K brackets and a short length of scaffold pole

some good info in here too http://www.digital-kaos.co.uk/forums...-setup-301108/

[dan20leeds]

what exactly does the motor actually do mate? plus, i have an 80cm dish, what is the best motor to buy?

[ramjet]

I would recommend the darkmotor superior or similar, but others recommend that technomate tm2600 instead , or maybe a stab motor

both can manage diseqc v1.2 and usals for controlling its movement

I think its pretty obvious what a motor actually does m8 !

With a fixed 80 cm on 19 east i would have thought 16 east would have been the hardest signal to receive a great signal on with your setup!

As Digicon stated LOS(line of site) should be looked at= also quality of lnbs..check your dish is also not (warped) you can check if your dish is warped if you either take it down or get high enough if the dish is at a height and look downwards..unlike zone 1 and zone 2 sky dishes an 80 cm should be completely even all round..i have to say this can take a trained eye and an experienced engineer to spot this one...also green moss/dirt/rust and even snow (albeit not permanent) on the dish facia can cause issues signal wise//// what dish have you got/what lnbs are you using? what meter do you use for alignment? Have you also checked the lnb scew on all lnbs as certain meters particularly crappy ebay ten quid ones wont show you what the scew should be set at... lnb bar could also be bent all over the shop...

Looking at your signal on 28.2 your dish is probably sound...but what do you base this information on? from a satellite signal meter or a certain receiver?

I would also recommend a motor as above too if you are now looking at discovering the amount of satellites you are talking about..i use a technomate motor but dark motors are good...if you go the motor route and your dish is exposed to the elements in any way then make sure the motor has metal gears although most motors have this now..

I would also recommend upping your dish size to 90 cm minimum if you are wanting 16 east on a diseqc motor!!!

Good luck

hi, before you put a motor on your pole make sure it is exactley up right in all vertical axis. if not the moter will not trac the ark as it should. if you set your system up ok use usals and all will be well kind reguards sidwho. ps you will find all the information you need on this excellent site
