lnb tests ,smart tit ,black ultra ,invacom twin c120,invacom quad c120

ive been doing a few tests last few weeks/months to try and get the best lnb i can they have been tested on a channel master 1.2 and a dreambox dm800,after each test lnb has been set with meter and channels rescanned on dreambox.

the smart tit has been modified to fit channel master feedhorn ,and the black ultra got the same treatment.


----------------


first test was modified smart tit channel master feed horn v/s black ultra standard feedhorn.

the lnbs were swapped within 10 min and same weather conditions.
i have re uploaded the pictures in case anyone wants to attempt the mod themselves.

2nd test modified smart tit against modified black ultra.this is done on a different day to the one above but same lnbs swapped within 10 min and conditions the same

a few more pictures from post above would not let me add them all to one post.


last test was putting back up a old invacom twin , invacom quad and then my smart tit (modified).

i only run the test on one sat 7 west.

inverto twin / quad / mod smart tit.

iraqi sports 43% / 40% / 44%
alsalam 50% / 50% / 49%

when i first put up the twin it was nice and dry , by the time i got the quad up it was light rain , by the time the tit was back up , it was heavy rain , and as you can see no signal at all on alforat.

i have one test left to do a modified smart tit / cm feed horn against the standard feedhorn , i didnt have time to do it when i first purchased it , but a new one has arrived today , so will leave a blank post below to add in the results.

pictures of 2nd mod to black ultra .

this test will now be with standard tit ,moded tit/cm feedhorn and 2nd moded black ultra cm feedhorn.

ok done the test tonight clear sky for a change .

looks like if you have a channel master 1.2 you need the cm/andrews/raven feedhorn to get the best out of the dish, ive not compaired the results yet from the moded black ultra long to the sort , but dont think there is a lot in it as i thought from before second mod.

black ultra seems better on the stonger signal 10e but weaker ones its is not the best and the invacoms in c120 will beat it .

ill look at the difference in results to see if its worth me shorting the tube on the tit , but at the moment i dont think its worth the effort the tit is well above in results if you prepared to do a little work,if not go for a quad or twin invacom with the correct feedhorn they are not cheep but could be the difference in you getting a channel or not if week.

ive now tested a icecrypt .1 quad (standard ) against the modded smart tit and cm feed horn after this month what sat mag gave it better results than a quad smart tit .found the results were very poor it could be the universal feedhorn was a better match on the dish they used,anyway results below and next ill chop off the head and mount it on the cm feedhorn.

clear skys.

Can't wait :D

what were the results with the lnbfs unmodified without the c120 feed better or worse

only the black ultra has been tested unmodified, i dont have fair results to give you comparing the black ultra in modified and un modified state , due to the time it takes the tests were done on different days , but can tell you the modified smart tit was better than it both times.

hopefully this weekend i can test the smart tit un modified against the modified one.

but from what i see the black ultra is at the end of all 4 lnbs ,5 if u like to count it modified as well.

but that is on a channel master 1.2 , it could be different on another dish i know poeple say the lnb aint going to make much difference on what you can pick up/see but it made a few channels watch able and that was only the few i tested.

Did they really call it a smart tit?

I'm going to get slapped if I walk into the shop and ask for her smart tit.

titanium

yeah its a smart titanium .1

thanks for all your efforts cosworth.

from the above though it seems you are really testing modified feed horns rather than lnb's ?

which from your tests would you consider to be the best c120 twin output lnb mate ?

no im making no modifications to the feedhorns as such, im modifying them to fit on the channel master feedhorn as they are not made in c120 form.
at the moment if you prepaired to do the work then smart tit modded to a c120 fitting, if you just want to buy and bolt on then invacom quad gave slightly better results but it was near enough new the twin is at least 5 years old could be a lot more.

is it a channel master dish you have?

From my side of tests,using the black ultra inverto on offset dishes i got very good results,comparing with other brands.
I dont have the smart tit to make a direct comparison with it,but i dont think the modded horns give the correct wave
to the lnb.

its a fiberglass offset echostar 1.2m.

ok so it has its own feedhorn with c120 fitting ? hopefully il test the channel master feed horn with modified smart tit against the standard smart tit this weekend ,but at the moment the smart tit modified to fit c120 is defiantly the best.

and im not being anyway bias i have them all here so i can just use what i find to be the best ,i could even keep the quad :biggrinjester:

i think those people mean the lnb wont make as much difference as a dish size increase . when buying a new full setup .

in all my tesing of lnb's and feedhorns i have found a vast difference . some lnb's tend to match better to some dishes and not others . some lnb's work simular on many dishes . some lnb's have better edge control and can benifit from a little focal adjustment . also lnb's can degrade over time mainly due to water ingress .

this is why tests like this are so important to others with a cm1.2 dish . it gives real numbers to real situations .

edit : is the quad the qdf-031 in the test ?

yes the quad is the qdf-031,gave good results that one , its was on route to new owner.

and one other point most people dont just go and replace a lnb unless its a good few years old , so a new one is almost guaranteed to give better results .

i think ive upset a few black ultra fans , but they do need to remember on a different dish it could give a lot better results end of the day it has a universal feedhorn to suite all dishes ,dont think you can beat a matched feedhorn.

but the results was still not what i was expecting when i matched it upto the channel master feedhorn.
