yeah can see them now , do you have to bond that lnb in or is it still bolt upto the feedhorn.
held by small bolts
thats ok then hes not putting it up the inside of the feedhorn.
is the feedhorn a c120 fitting.
if so ive still got a offer for you il send the modded smart tit for you to compair against the modded black ultra when you get it.
just really need to know if its a improvement on other dishes.
ill pay the postage both ways, as long as youre prepared to carry out the test.
yea its a c120 mate no problems ill test it for you ,decent dishes fibos are, they do punch slightly above there weight so would be interesting to see if its better than the modded BU ,ill let you know when i get it be end of month now
hes offered me this Mod also mate saying its as good as a BU ultra twin Octagon Twin Slim optima OTLSO PLL LNB (attached pic) they any good ?
just to add c120 lnbs usually fit onto a flange thats inserted into the feedhorn then a couple of alan key bolts tighten up onto it to keep in place modded lnb's go straight into feedhorn and are tightened that way

The Octagon Optima range have a slightly better gain 60-65 compared to the Black Ultra 60

cheers mate,its phased locked loop ,i had a read up the phase is locked to same as input phase something along those lines
Its to do with a change in temperature and how the LNB reacts with the drift of signal and locks itOriginally Posted by simon 2003
i didnt find that the black ultra worked that well standard or modified on the channel master , if the guy is saying that the octagon works better on youre dish id go that way and try the octagon hes obviously tried them both.
dont look like hes doing a bad job either as hes making a complete new end not just doing a chop and bodge
this only causes one problem now , im going to end up buying one myself to try, :o10:
ive ordered a octagon lnb today , ill post the results as soon as i can.
couldn't resist it , :o15:
Very interesting and worthwhile thread..
Cosworth4X4,, either you got a steady hand ! Or a Fancy Camera ! :respect-055:
Excellent Do***entation of your research and transcript.
P.S the banging of heads was a Great Read!
Honestly Lad's ! It was Constructive in every Manner.
Some Dissagreements about "absoulute" figures, and a shut down of the thread.?
What's New.....
Only makes the weekend more to look foward to.
.
(new installed super black, mounted MidWay with a batter'd triax 110 made a vbig improvment.)
Now If I won the lotto ?
Wrap Up well for Feburary,,,,,
:bravo-009:
I am trying to catch Eutelsat 36E in Denmark, Copenhagen. Every dB/% matters. I am waiting for my channel master feed horn to arrive soon and then will put it to test.
Octagon is not making c120, is it? I can't find it on the net with c120! Although on the Simon's picture it looks like c120 factory made.
no they dont thats why you have to modify them youreself if you want to put them onto a c120 fitting.
same with other makes that no longer build for c120.
lol you must have a shed load of lnbs,,,only drawback to mods is weather proofing as my black ultra has started to play up now
ive sold most on , at a loss :ack2:
yeah you need a very good sealer luckily i got some from work its used on sumps ford and Peugeot.
ive never seen anything stick/seal as good .
Could someone clear up a point re the Octagon C120 picture posted by "simon 2003"? If I have read the thread correctly this is a mod imported from the Netherlands, can anyone please PM me a link or contact details for the supplier as I am interested in testing out one of these on a 1.5m Precision Prime Focus dish to see how it compares with an Invacom C120 and an Inverto C120.
Rgds
As the main UK supplier I can tell you that Octagon are not producing any C120 LNB's only offset ones.
