Hi
i have an 80cm dish(moteck motor) with 0.6 lnb and get reasonable reception on 28 19 16 13 10 7 east and 30 west ...ufortunately when the trees fill out during the summer 28 e disimproves considerably ....would a change to a 1.1 m dish improve things much?

I would suggest you invest your money in height not size, however your saying reception is reasonable so maybe a little of both wouldnt hurt.

Basically the leaves will still be infront of your dish, so height is a priority.

It depends on what you mean by "disimproves considerably". If the channels are breaking up, then a 1.1m should make enough of a difference to bring you over the threshold and give a stable picture. If they are completely gone, it may or may not be sufficient - it depends on the signal quality level.

Line of sight is more important than height per se - could the dish be moved to a different location with clear LOS?

Of course, if you go sufficiently high enough, you can usually get LOS although the dish will be more exposed to wind.

Thanks folks..think i may invest soon

save me starting a new thread ........im thinking about getting a 115cm dish here - http://www.corksat.com/oscommerce/product_info.php?cPath=28&products_id=52

I currently have one of those lidl 80cm dishes and a superjack motor. Just wondering does anyone know if the wall mount etc from my 80cm dish be able to support the 115cm dish? As that 115cm dish isnt so cheap if you have to buy mounts etc

MisterAnarchy

I wonder what kind of gain there is on that 115cm dish ,would the Triax 110cm for €70 be a better option ?

watty

110cm dish even is close to edge of windload for *ANY* coax powered Diseqc motor unless it is very slow (more gears).

I have no idea what your wall mount is. If it is a Lidl mount then it is already too flimsey for 80cm on a motor!

110cm is NEARLY TWICE the windload of 80cm, the 115cm is OVER TWICE the wind loading.

Obviously there is a static weight issue too as the dish gets bigger, but since at 60 mph gust the wind load can be several tons ...

Triax dishes have a good reputation for gain vs size. Not all dishs have same efficency, which varies from 50% to 85% depending on dish accuracy of curves, surface deformations, dish deforiming under own weight or in wind, feed design and LNB placement accuracy, match of focus rings/integral horn of LNB to Dish F/D ratio (how far the focus is out from dish relative to size of dish, the "cone of view" of LNB should only just "see" whole dish, rather than the middle (lose signal) or overlap (pickup noise).).

Personally, I'd go for the Triax 110cm dish. They're good long-lasting dishes IMHO.

Cheers ,will go for the Triax so.
Gonna pair it with a Moteck motor and a Technomate CI 1500.

I think the triax is out of stock for a week or two. i was in the shop at the weekend.
Although if they have them let me know here thx.

any info on where i can get one ,hopefully in Ireland as to save on postage?
What are those Lidl 80cm like?
I would like max 90cm dish to pick up eutelsat and hotbird (min 80cm).
thanx in advance

see the sticky for Irish suppliers

Maplin or www.satellite.ie or see the stickies.

Lidl only sell sat gear occasionally and not anything bigger than 60cm lately.

i ordered a 115 cm dish off corksat with a suitable wall bracket for 83 euro incl. del.,which is very cheap for ireland.hopefully putting it up goes well . how can zintek get away with selling moteck dg2100a motor for 125 euro,costs only 40 euro on german sites.i pity the people who fork out that much for a motor.

johnnyboy4711

anyone have any idea which is the best sat online store in germany?
with some english on the website would be great!
thanx

Well in fairness they will keep selling at that price as long as people keep buying.

I think hmsat.de are good.

Run the website through Langauge Tools in Google. It'll give you a basic translation that works mostly OK..

hi there!
does it really matter on non-brand dishes(which corksat have) as supposed to branded(ie Triax,Gilbertini etc).
thanx

i got a 1.15m dish but cannot get signal.the dish is in no way symmetrical.my lidl dish is symmetrical looking form the top down.i take it my dish should be symmetrical along its longest axis like the lidl dish?.cannot get any signal with it after hours of trying.

watty

It is MUCH MUCH harder to find a satellite with a large dish.WHat kind of satfinder have you?

mayto

i just have cheapo lidl type satfinder.is it okay to use these to tune in 1.15.m dish?i am well used to putting up diseqc motors with 80cm dishes but cannot get a signal with this dish.the dish just does not look right.its in no way symmetrical,should a dish like this be symmetrical?i think courier damaged the dish.supplier will send out another one but i would like to make sure the dish is at fault.

watty

It should be east/west symetrical. But won't be up/down symetrical.

A 115cm dish is really 4 to 6 times harder to align.

You need to set approx elevation and then move East/west VERY slowly.

If elevation is out by an amount that still just gives a picture on a Sky minidish you will get NOTHING, no signal at all.

mayto

dish in no way east/west symmetrical.courier must have threw something on it to knock it out of shape.will try again today with help of supplier to see can i get any signal with it.he will not have 1.15 in stock for a few weeks so i may as well see can i get any satellite tuned in.

ordered 88cm triax,smart 0.2db LNB,and motek motor incl postage for
€118.
not bad eh?
they sent me the bill through paypal,paid it and its on the way,way-hay!

That sounds very good.

OT, what is with German retailers who don't seem to directly take Credit Card details, sometimes opting for Paypal?

Great deal, nice one

got a few satellites tuned in with my 1.15 m dish,(28.2,19,13,7,5 EAST) and (8 ,15,30 WEST).but i cannot get thor 1w or eutelsat 16 east.would a warped dish stop you from getting a few satellites?. i could get all possible satellites with my 80cm lidl dish incl. thor and eutelsat,but i cannot even get a stronger signal on any satellite with this dish .

byte

A warped dish would definitely affect the levels of signal reaching the LNB.

Recently I am loosing picture on BBC sometimes , and during heavy rain UTV/ITV also go , would the purple beach (in front of the dish) be the prime suspect , or has BBC signal gotten weaker ? This was not a problem last year but I changed dish and added two more LNBs in Feb.

Secondly, can someone remind me of the distance required to get clear reception over a tree ie ; if I have a tree which is 5m higher than the dish, then the dish needs to be 10m , 15m ?? back from the tree .

Thanks in Advance

Yes, the tree must be prime suspect. Also, it may not have been set up as well when you changed it in Feb.

The angle is aprox 22 degrees, depending on location. Therefore, dividing the 5metres by tan (22), gives about 12 and a half metres.
But remember, the tree will keep growing, so leave even more distance if possible.
