It shouldn't Something is off.
Satellite is on the same position for any transponder. They do have different power and antennas, that is the reason I always use the spectrum analyzer to see the peak of each transponder, tell my son (MiaSat) what the heck did with a $900 device.... grrrrr

But still you did a GREAT job. I dont think you can get more juice than that, almost the same level a signal possible a little more quality but without having the proper tools I cannot say if the measure is accurate or not. By the way I Used for my 1,2m a V9S Super that was forgotten with spider webs :oops:

And last, Hey etlam a 1,8m is not much of a difference there

Finally got the titanium and yes it’s worth every penny! 77% on byu, about 3-5% more on other tps, now i got univision also. Still can’t get cw when the sun is out. I’ll try later during the evening.

BYU on G17 and ZNS bahama on ses 2 are the strongest I get here in the mid atlantic area...

Thats good to know, do you know other transponders i could try to get with the titanium lnb and 1.2m geosatpro dish?

entre mas grados tenga el lnb mucho mejor tengo un 25K

I like ses1 at 101w heros and Icons, decades and movies 3957 v i think they usually do well for me even with lower signal quality than some others note the lower fec numbers( error correction) important for smaller dishes as well as no active transponders on the closely spaced adjacent birds

No esta mal, cuanto mas alta es la temperatura es mayor ruido
un LNB de 15K es mejor que 25K
La forma de medir el Factor de ruido es a traves de Grados Kelvin (hay tres maneras) cuanto mas cerca de ) el nivel de ruido es menor ego el LNB es mucho mejor
La otra manera en en db, 0.1db es mucho mejor que un LNB de 0.3 db

hola yo lo lo decía porque tenia uno en mi antena de 3 metros de 13 k y lo he cambiado por una de 25 k y me subió 2 puntos de señal
por eso dije que era mejor gracias por tu aclaración no sabia eso

That cheap lnb on the picture can get both cw and the fox mux 3820. Titanium can’t. Thats weird.

No is not weird etlam think,
If you eliminate noise, electromagnetic interference , white noise, spurious emissions through those premium LNB, because that what they do. They tend to ALSO eliminate low power TP
But also these "premium" LNB are very sensitive to alimnent, a just simple 3/64 inches AKA 1 milimiter makes a HUGE difference.

Example:
I am surrounded of "radio garbage" 4 Military radars, three 4 LTE towers each one 5 providers each.

Common LNB It did work, BUT the signal fluctuates.
Titanium solved that problem, but was more difficult to me to adjust it, why? I can say it in easy words.. it like it "narrows the beams" make it more difficult to align it, so just a minimum adjustment it can make you loose 1 or more TP usually those with low power
It Happened to me on 55.5W. in less than 1 minutes I got the Sat, 2 to 3 min to supposedly perfect alignment. Scanned and wow! 95% Signal and most of the TP's 74 to 85 % quality, then I realized through a friend I did not get the Fox and FX from Argentina and Chile, go figure! I didn't even touched the LNB screws just forced a little bit and Voila ! That TP Showed up!

But The problem FOR ME that when I align the LNB I have to go facing the dish with a ladder so, I am not skinny, though I am taking 1/4 of the dish, hence the signal drops or because of refraction goes up! giving me false readings.

That is the reason I invested on downconverter block PLL LNB. So I can adjust in Ku Band then C Band is done
