C-Band/Ka-Band Reception in the UK (Dish Project: LNBs, Dish, Alignment) - Post your results here...

Use a Linear Sat without the plate to set the skew, which of course makes it very difficult as 3.3°E was active when I set mine up. Now we've got 46°E, the even weaker 38°E, prob better on the West Arc 37.5°W, 45°W, (weaker) 50°W & 55.5°W.
Then the plate goes :
:thum:
Just an update from me ....
Moved the 1.5m to location that I thought could see 55W and nothing yet
In fact still nothing linear polarisation at all on c band for me.
Back to the dielectric plate....
here is a strange one relating to the dielectric plate. Moved it to the opposite "wrong" position so that I have R=H L=V
40.5W SES 6
3980 R VOA
In normal position R=V, L=H I get nothing at all from this TP, other way around "wrong" position, comes in lock with watchable (small breakup) image.
The LNB feed does have 4 grooves at 90 degrees apart. Im assuming they are there for the dielectric plate to go in both ways around ?
Not tried any other sats other than this one, on blind scan seem to have more channels than before but not taken a good look at the list to be sure.
Any thoughts ?
Hello amdade,
i cant help with your equipment - because im using a Seavey Feed with mechanical polarisation. So it makes no different for me to receive a lineare Satellite or not. Both are working with this Feed without moving a dielectric plate in or out.. ( a Chapparal-Corrotor is also working )
If you want to receive the IMC Worldcup 2014 Feed on 55 West - i must be honest: you will not get it with 150 cm..

Hello amdade,
2,3 meters. If Trees are in the Focus - you can calculate on this side if you are wrong or not: http://satlex.us/en/elobst_calc.html

I am sure once you get the LNBF's skew correct you will get these channels with the plate in the correct position and weaker or not at all in the wrong position.
Yes Im sure you are right empb.
With antenna pointed at 1W, I have the two probes set vertical / horizontal. Im east of the greenwich meridian by about 1 degree.
This should be more or less correct ?
Just another FYI have the two ESPN TP's from 40.5W also with the plate in its current position. 3758 L and 3980 L

Perhaps a bit of a breakthrough a linear channel no plate installed. Think tree problems confirmed, with a new sat position for me.
Looks like my skew position was about right as set up.
37.4W NSS 10
3756 H 1777 Silverbird TV (in English)
I will do another blind scan now see if anything else appears
As I type the wind has eased, Signal 87 Quality 60, wind blows trees move, up and down S/Q goes, sometimes drops out completely.
So.... need to find another location for the third time All good fun

Embp i need c band lnb
An update from me related to the 2.4m fortec star antenna ordered couple of weeks ago...
Arrived well packed, but I was quite surprised with the weight of the package, could only just move it by myself.
Assembly fairly easy as long as you use an upturned bucket to support the petals at the centre, and take your time building it. I put the support assembly onto the reflector face down, then lifted whole thing onto the concrete pad.
Seems to be designed for C band, feed support arms come with holes to connect direct to a scalar ring. The unit came with an a KU LNB adaptor plate which I have not used.
Plus points :
Very low cost £195 inc delivery
surprisingly good build quality reflector
Decent results from 55W where it is pointed at the moment
Needs improvement
Nuts were not all well made I had 5 that were not threaded properly.
No washers included
Anchor bolts not easy to use, not quite long enough probably will have to replace.
Az El base not the best, the Az part is not really adjustable a case of move the whole thing around not easy
The base is going to rust, in fact already can see some issues around the bottom where I have been moving it. Hamerite needed.
Wish could buy the polar mount to go with it
No useful instructions
So the results.
Have C1W-PLL on there at the moment, Technomate TM6902 :
220 channels scanned…
4004 V IMC Worldcup 2014 signal 87, quality 68, works well, no luck with Sportsmax 1 or 2 on same TP
3846 V Fox + others, signal 89 quality 63, working, thanks to all for software upgrade
Not tried other satellites as yet may try for 58W next, not done this yet because wanted the IMC channel and how difficult it is to move.
Next step to find a polar mount for it….
Can upload some pics if of interest. Any questions fire away…

I'd like to see some pics of it, and more importantly I would very interested it you could get it motorized.
Please keep us updated :thum:
Yes that was kind of part of the plan to use the reflector on a n other polar mount maybe even replace the the IRTE 1.5. Im thinking now keep my 1.5 as is and add a polar mount to this one. May be next summer project...
Also should have said this is a HUGE dish, I should have realised but there we are. The petals are heavy
first try to upload photos here goes

Any up to date channel list
Has anyone got a list of possible channels and feeds on all the C-Band Frequencys. thanks
