    C-Band Reception in the UK (Dish Project: LNBs, Dish, Alignment, etc)

    A friend will be re-installing/re-aligning my Dish next month as I am sick of getting nothing from 4W, when I know I used to get some of the Beams (also lost ENTV on 5W).

    My East Arc is set up stronger at Present (Badr4 26E superb even in bad weather). But I think we Aligned on 13E and adjusted on 26E last time, need to do it right on 0.8W/1W this time (my reception Satellite Arc is generally 45E to 46W (telegraph pole obstructing a big arc).

    I seem to remember the Baltic Beams were the weakest receivable ones in the UK at 0.8W/1W but I can't remember the frequencies to use, can anyone help? (11747H ?, 12687H ?)

    I'm using a Triax TD110, location North West England & will prob replace the LNB and use a Inverto Quad LNB to supply my Topfield twin tuner, Manhattan twin tuner, Spiderbox HD9000 and Humax HD receivers.

    I am also considering adding C-Band but it would be an offset LNB ie something like:



    don't know what type of arm but would be Ku-Band Prime, C-Band offset, anyone think this would work for 3.3E C-Band in the UK and any other C-Band between 46E and 31.5W (e.g. 5W, 20W)

    I suguest check [Only registered and activated users can see links. ] for the transpoders that are the weakes .
    For Danish users it generaly 13e for dish allignment .
    Recheck your pole is 100 % in level .

    Lyngsat only gives you a general info (eg dBW / EIRP) based on manufactures supplied footprint info, satellite manufactures supplied infos. (Although some information is based on there own reception reports, which I believe are London based, not North West England).

    Weakest signal (beams was prob the wrong word to use!!! ) depend on your location, which is why I mentioned Location: North West England.

    And a good one to start with. I'd forget the c band lnb's feedhorn even if it is an offset one, just don't fit it so you can get them as close as possible as you are pushing it on C Band on a 1.1. Also cover the C Band lnb's cap with plastic to make it waterproof as C Band lnbs are designed for prime focus dishes which means they always face down so only usually have drain holes but on offset dishes they point upward.

    You can make a second lnb holder easy enough for a c band lnb with a U bolt - 65mm I think (can't remember tbh).

    In offset on a motorised it isn't as good as you move away from the top of the arc as if you use an inclined actuator & fit it above the ku lnb so you get all the focus (not easy on a Triax ) & at 1.m- 1.05m you are already on the limit. There's a lot of C Band up there though, don't forget there's circular & linear so access to swap the dielectric plate's not a bad idea either.
    the 6 degree offset does work on a td110 although reception site is down south and he did use lightweight ku-band ultra lnb's. thanks to satellites.co.uk/@vipersan for the picture. regards mdt

    Re: C-Band Reception in the UK (Dish Project: LNBs, Dish, Alignment, etc)

    Properly installing the LNBF on your dish is critical. After attaching the scalar ring to your support arms, you should confirm that it is pointing to the center of your dish. One way to do this is to measure from the edge of your dish to the edge of the scalar ring in several places around your dish. These measurements should be the same. If not, your feed is not pointing to the center of your dish and will not perform as intended.
    After finding a signal, turn the LNBF to find the best polarity performance. Do this on both polarities. Carefully move the C-Band LNB toward the dish and away from the dish to find the best operating distance. After finding the best possible performance tightens the set screw to hold the LNBF in place.

    SDG
    So as the majority of C-Band in the UK (on the Satellites mentioned earlier in this thread) have L / R circular polorization I would need to leave the dielectric plate fitted. Or remove it to get alignment with strong Linear 3E C-Band transmission and then re-fit it as I would want to get the circular L / R channels?

    I also found this:
