Triple LNB ?

Lol it was port 3 & 4 for me to.when i switch them round it worked for me.

For linguistic reasons (I'm a translator), I'm only interested in Thor 2 at 1W (primary interest) and Hot Bird at 13E (secondary). I see you have the (empty) LNB holder for 1W at the very end of the bracket. Do you think it would be a feasible solution for me to place my 1W LNB in the middle of the bracket to pick up as strong a signal as possible, with the 13E LNB away at the end (I believe the Hot Bird signal is quite strong)? And would it be possible to fit, say, an Invacom Quad QDF-031 with Channelmaster feedhorn at the 1W position to improve the signal? Can you remember getting any channels at all at 1W (most of them are Conax-encrypted and I shall need to buy a card). I'm thinking of getting a Triax TD-88 or TD-110 dish - any comments?

Hi Charles. Thanks for reminding me of your situation. I answer a lot of questions, and it all gets a bit confusing sometimes

Working backwards through your questions; firstly, I would definitely go for the largest dish - the TD110, to give you the best chance of success (or an even larger dish, if you can accommodate it).

Yes, I had reasonable success with 1W on my TD110, though I receive all of Thor2 well on my TD88 too. I haven't spent much time at 1W for ages. I'll have a scan later and post some results if I remember.

The Invacom quad/Channel Master feedhorn will probably be an expensive waste of time, as the CM feedhorn is exactly matched to the Channel Master dish, and so will only give you a performance boost when used on that particular dish (in theory at least).

The Invacom Quad might give you a little bit extra, but I don't think that Triax make separate feedhorn for the TD110 ( :?) so you might as well go for the integrated feedhorn version.

As for setup, I think the best way to approach your situation would be this:-

Setup the Hotbird LNB first, and fix it at the extreme westward end of the multi-LNB arm.

Guesstimate the required slope of the arm, and then peak the Hotbird signal from the dish az/el mount.

Now throw the 1W LNB on (slightly east of centre, probably) and tweak the slope of the multi-LNB arm and the lateral position of the 1W LNB until you maximise the signal there.

Then you should revisit the Hotbird LNB/arm 'slope' to see if you can improve the signal there by tiny adjustments, then the same minor tweaking of the az/el mount, followed by re-tweaking the 1W LNB etc. etc.

Just keep going around this loop until no further improvements can be seen, and that's the best you'll get out of this dish. Use BBC World to set up 1W, as it's nice and strong, is FTA, and is immediately recognisable on-screen.

If you can now receive Thor2/3, then all well and good. If not, then you plan has failed.

My reckoning is that you'll get Thor 2 no problem, but you might struggle with Thor 3 if you're 'Down South' (sorry, can't remember).

Hi STICK

Thank you for your reply ... it's given me both information and assurance. I think I'll go for it: a Triax TD110 dish with a pair of decent LNBs on the 20-deg bracket ... and set up according to your advice.

With respect, I'm not entirely in agreement. I have a Gibertini OP150cm dish in Denmark (we live there for a few months of the year) on which I tried without success to pick up ITV/STV Grampian, BBC Scotland 1 and 2 off Astra 28.5E - until I fitted the Invacom quad and CM Feedhorn, and the missing channels came in 24/7 clear as a bell (along with all the other 100s of FTA channels I had already been getting). So it is possible to fit non-matching components together and get a good result ... ... but maybe a less ambitious LNB will do this time to pick up 1W from my location: the Moray Firth coast about 50 miles NW of Aberdeen. I have a spare MTI 0.6dB Blue Line - maybe that could be used for Hot Bird reception (13E), while I use one of Triax's LNBs for Thor 2 (1W).

Any suggestions for a receiver? I've been thinking along the lines of Technomate TM-1600 2 CI Super. Any comments?

Hi m8,i have 3 tms,the vantage is a better receiver for about the same money.

Do you know Sid i'm starting to get feeling that you really like the Vantage receiver

Dr. Dish has a lot to answer for

Hi nano.i do lol,i did say 2 you before you got your technomate :roflmao:

Well, feedhorns are matched to dishes, so if you get a result with a C120 and the wrong feedhorn, it's either down to the superior LNB, and/or you've been lucky that the dish illumination patterns match well.

Maybe you'd be better with a Gibertini dish and multi-LNB arm, as they DO have matching feedhorns.

The Techno 1xxx is a good choice of budget receiver, and is almost certainly the no.1 selling non-sky receiver in the UK.

Hi stick,since the vantage came out in the uk,there a better budget receiver by a long chalk.to me soon vantage will be no 1.once people get wise

SatSid ... thanks for your mention of the Vantage ... I'll look at it.

STICK ... thanks for your advice ... never thought about it like that ... that a good LNB could balance out using a feedhorn with the wrong dish.

For the records, do you know if there is a corresponding multi-LNB arm for the Gibertini? Or would the Triax bracket fit on the Gibertini?
I should add though that I shall probably stick with the Triax solution - and follow your setup instructions.

Charles

Yes, there is a multi-LNB arm for the Gibbi.
