    I only require a single out put or are the doubles better?
    Seen one on *bay = 120907441518
    Is this OK?

    Whats the signal strength on ZEE AFLAM on 7W - Im getting a pic at the moment but breaky 34%
    Are you able to get a signal lock on the Add Packahe on Horizontal angle - Like Ten Sports etc?

    a single will do but maybe worth thinking ahead whats the chances you may add another receiver or even a twin tuner.

    i can only get 31% on zee aflam at the moment but thick grey clouds and its been raining.

    ive not checked the other package but if its h on one of the older sats at 7 west dont think its possible on a 1.2 were i am.

    How do you cut the front face off the lnb. Is it just a hacksaw job - or something more sophisticated?

    first one i did i used a chop saw does a nice clean cut not a lot of work req to clean up the surface, last few i just went to the good old hack saw takes a bit more work to clean up the surface but had a orbital sander didnt take too long then.
    make sure you put some tissue paper in the lnb to stop the fillings going inside.

    come back with youre results.

    Have you found a gibertini feedhorn yet, and if so how does it compare to the Channel master ?

    I bought quad invacom black LNB.
    And can surely confirm that works great on my 220cm dish.

    i decided this week to get a gibertini feedhorn to see if they are as good as recommended by digicon and have to say the results are very poor biggest waste of £28 i ever spent but i had to try.

    7 west. cm gib

    jsc sports hd 55% 41%
    iraqui sports 58% 48%
    alsalam 59% 48%

    10 east

    ortc 47% 26%
    syria 52% 39%

    both tested with modded smart tit and set up with meter and clear skies , the gibertini was at best 10% down on signals a lot worse on 10 east so bad a small shower or heavy cloud is not going to get you a signal .

    so if you not going to pay up the extra for the matched cm feedhorn then you be better off using a standard smart tit or inverto.

    you want the max on the weaker sats so far its still the cm feedhorn and modded tit for the channel master dish.

    Well I finally got around to modding a single Smart White Titanium 0.1dB.
    Cutting with a hacksaw and cleaning the surface with a broad file was relatively easy.
    The problem is the remaining flange diameter is three millimetres too small to fully encompass the four C120 flange screw holes.

    Anyway I did some comparative testing on 5E, BBC World.
    In all cases I did not move the dish, I only adjusted the skew and more importantly the focal length to optimise the signal strength for each LNB.

    My dish is a very old 180cm prime focus with F/D of 0.468 and unknown feed horn.

    With the LNB I'm currently using (Inverto White tech 0.3dB) I got 73%.

    With modded Smart White Titanium the best I could get was 69%.

    Finally I tried my old black Invacom and got 76%.

    Therefore, I've left that in place!

    So, to conclude. The modified Smart White works fine but not quite as good as the dedicated C120 LNBs with my dish and feedhorn.

    Interesting afternoon in the sun

    i only use 2 made up bolt holes and they are only half holes its strong enough to hold a lnb in place.

    shame you didnt try on a weaker signal , as if i remember correct the invacom did improve on some stronger signals , but not the weaker ones.

    but if you got a 60% or a 90% you not going to see any difference on youre tv.

    its the weak ones you cannot get or disappear in poor weather , thats you need the most from and where i live its **** weather 300 days of the year.

    got any pictures of the smart tit.

    Good to see someone else giving this ago

    However the big test is to find a weaker signal with your original lnb (say something on 7w or 26e etc that is pretty low) and then repete the test again with the smart and your old black and see if there is any difference then.

    Out of interest where abouts in the world are you, as i've just checked bbc world on 4.8e with my 1.2m channel master (with the hybrid smart tit with cm feedhorn) and i'm seeing 73% signal in sw uk.

    @CokeAddict
    I'm in West Yorkshire.
    I'm pretty sure the feed horn is not correct for my dish.
    I've not been able to find one with the correct F/D so, in general, I get the performance of a 150cm dish.
    Mind you the tuner sensitivity is also a factor. With my AzBox (with which I did the testing) I get 76% (using the Invacom) but when I swop to my DM7025 I get 80%.

    I'll try testing with a very weak transponder when I get some time.

    im even further away and im getting 56% on bbc world here is the footprint.

    ive got a gibertini feedhorn going cheep

    only a joke not suitable for youre prime focus.(or much else)

    hopefully digicon will buy it off me as he likes them so much.

    I've just tried on a weaker transponder
    ORTC 10e
    With the Invacom I got 55%
    with the modded smart white tit I got 54%.
    Low heavy cloud.

    So not much difference on my dish - but the smart white single is a lot cheaper if you are prepared and able to do the mod.

    I was then trying on 7W on JSC Sports only 10% (no lock) with the modded smart white and 56% on ALSALAAM and it started to rain heavily.
    Therefore, I could not compare the Invacom.

    I'll try again in clear weather.

    Incidently, the white plastic feedhorn cover I took of the smart white was a perfect tight push fit on my old, original feed horn.
    That will stop the spiders nesting in there!

    the fact that your azbox gives less signal strength than what your 7025 does is totally academic mate without you also comparing the cut off signal strength.

    you may find that the azbox starts to break up at 5% less signal than what you 7025 does.

    eg azbox starts to break up at 35% signal and 7025 at 40% signal.

    if this were the case then the results would be exactly the same with both boxes as these signal meters are only a guide and not gospel

    @ cosworth

    think that has to be a really old footprint mate,prior to the latest sats going up,because i have a 1.2m in manchester and so clearly outside of your posted footprint area,yet i can receive 85% signal,perfectly locked on bbc world.
