nOOb working on a first time dual LNB set up

nrgetic99 · 01-03-2009

Greetings,

Another Brit abroad here. Find myself in the Hessen region in Germany for a couple of years. Need a dual LNB set up to find Astra 19.2E for my local Premium channel set up and then Astra 28.2 for FTA channels that remind me of home. I am in rented accomodation but do have a really nice South Facing "DachTerrasse" or rooftop patio so I have essentially free reign for dish placement.

Total nOOb but read a lot here before joining.

I think I have a very good overview but will have some seemingly dumb questions to follow.... please be nice

My first simple question. I am somewhat limited to the HD receiver provided by my Premium Programming provider (in a contract, yeah...I know

) . The receiver they will send me is a Phillips DSR9005/02 which says it has 22 kHz tone switching. I am looking at dual LNB's, an 88 cm dish (my research tells me that would be fine), when set up, I would like to be able to view programming from both 19.2 and 28.2 .

I assume I will use a DiSEqC switch and then a single cable to the receiver.

As for the dual LNB's and the nice PDF setup guide in the stickies, from experience, anyone know which will be the stronger, 19.2 or 28.2 so I know which one is set up direct and which is offset ? Goes without saying, for setup purposes, run a cable direct to the receiver from the central LNB first and get that working then worry about the offset and switching later after the Receiver/Primary LNB/dish set up is proven.

Oh yeah, and as I am in rented accomodation I will be using a ribbon cable for going through a lightly used window seal as I can't drill holes. I have read any connections can impact signal strength/quality but it seems many others seem to get around this problem and use ribbon style cables.

Any major flaws in my plan ? Advice ? Anyone in Hessen wanna come help me set up for free beer and pizza ?

Thanks

Welcome,

Td88 dish with multi-bracket arrangement required. Weakest satellite at focal. See also http://www.satellites.co.uk/satellit...guide-pdf.html

As for the 'ribbon cable for going through a lightly used window seal', personally they can cause signal loss.

If your going to use a sky receiver for 28e then run a seperate cable for each. If your using the one receiver then a 2x1 DiSEqC switch required. The receiver will switch between the LNb feeds.

If your contract receiver has 22kHz switching that usually means it will work with a Universal LNB, not switch between two or more) of them.

You need to check in the specification if the receiver has DiSEqC 1.0 or above, if not then you will need a manual switch between the two LNBs.

It does, I've just checked

Your response time here is amazing !

Many thanks. Will try and source as much as I can locally but that has issues with the language barriers (I have 3 months German and doing OK) and I worried I will get the wrong equipment so I will probably do all shopping online.

Seems the Phillips will work just fine.

Not a Sky receiver, just want the Beebs etc from 28.2 with the Phillips.

I may try and do a really clean through wall set up for the cable but the Building owners are very picky.

Finally, any brand recommendations for the LNB's would be welcome but from my reading here, a 5 Euro LNB can work fine , its just seems to be luck of the draw. Thanks for pointing out the twin LNb guide..I had actually read that this morning before I posted.

Will update as I progress.

Thanks

Great ! I have been surfing and cannot find that detailed info..where did you find it ?

Thanks

Some of the BBC channels in Hessen with a small dish may not be receiveable

Thanks for the info. I have found info that suggests 80 cm will be fine and there is a chap in Frankfurt (30 km North) that says he is having no issues.

I hope an 88 cm will work as much bigger than that will be a problem at my appartment/flat.

UPDATE :

I found this _http://www.sateuropa.co.uk/information/free-to-air/uksatellite_channels_footprint.asp and it looks like I am right on the line of 90 cm so 100 cm would be safer.

If your keen on Traix, they do Td110 (1.1cm) although the dimensions are more accurately at 1m.
With multi-bracket always set up the weakest satellite on the focal. In your case 28e (2D) and offset 19e feed. From behind the dish the offset LNb for 19e will be on the left and postioned lower than the focal LNb, with the use of titling the bracket in that direction. This applies with the Td LNb bracket. Behind the dish meaning: stood behind looking out towards the sky.

BTW, I am located essentially in the center of the City of Darmstadt.

Again, great quick info.

I am just going to get you to drop by on your way to the Canaries

Thanks again,

lol, yes I do that trip regulaly enough.
Good luck.

nrgetic99 · 01-03-2009

Followed one of the posted links (thanks) and got this.

"Darmstadt - City Centre
Receiver: Strong SRT 4155 Evolution FTA Box
Dish: Strong 80cm Dish
LNB: ALPS dual o/p
Posted 30-08-03
I bought a Strong FTA 'Starter Pack' in Germany containing all the above. Astra 2D signal is clearly weaker than 2A/B and Astra 19E, but I can get all the BBC FTA channels perfectly OK even in heavy rain. "
This guy must be less than a kilometer from me. I know its annecdotal but I think I will start with an 88 cm

Thanks

A little more research shows an LNB with a "DiSEqC loop" so that you do not need an off board switch. The illustartions shows a twin set up with a regular single LNB looped into this LNB with the DiSEeQ loop and then a single cable going off to the equipment.

Not sure how your German is but _http://www.neckermann.de/index.mb1?mb_f020_id=ehBVbERPdDYNpzn6JKLA10QLaPjLL jH9&nav_id=18675547&vkh=0461&wersch=15334&link_id= YPyAtsjitUng78RhWvAE10LszHjas7&ct=1

Forgot to add..

I found this place by finding this thread

Great thread and info and I learned a lot from this before I made my first post.

I did some more surfing and came across the Technisat Multytenne. It is available locally quite reasonably and I did find anecdotal evidence of a user no more than 10 km from here and getting the Beeb.

However, the spec tells me it is pre set with multi lnb's for 13, 19.2 , 23.5 and "Eurobird 28.5" according to the box.

I have seen multiple threads of folks claiming 28.2 with this setup.

Sorry for the rookie question but is this a different animal ??? Is it possible to get 28.5 with a system pre-set with an offset from 19.2 for 28.5 ??? Sorry again...

some of the sky channels at 28.2 actually come from 28.5
