Geosatpro C1PLL LNBF - C-BAND vs BSC 421

<< < (2/3) > >>

Pyro:
I changed the subject to vs BSC 421 since I'm now able to scan more channels with the 421

Add to the list :

91W
3820 V 30000 @ 67%
4020 V 31250 @ 44%

99W
3810 H 3253 @ 56%
4080 H 22760 @35%

Seems to me that the channels that are on the edge of staying locked on the 421 are not locking when I put on the C1PLL

Pyro:
I updated the title to note that this lnbf was the geosatpro version not to get this confused with the titanium version under the same name(hope to have one soon for comparison)

Keep in mind that you are using a 1M dish which is VERY undersized for C-band. Your dish is actually receiving signals not only from the satellite you are aiming at but also both east and west adjacent satellites as it is not 2 degree compliant. 

What this means is that being more sensitive, your C1PLL LNBF could be receiving not only a higher signal level from the satellite you are aiming at but as well a higher level of adjacent satellite interference which would greatly contribute in not being able to scan and lock certain transponders.

In order to do a proper performance comparison between the C1PLL and the BSC421, a 2.4M or larger dish which is 2 degree compliant must be used.

Pyro:
Agreed, take my findings with a grain of salt. If you were looking to see if you can get more out your undersized dish on Cband using the Gesoat PLL or DMS 421 then I would stick with the DMS. Could be a different story on a BUD ? Next is to test the Titanium C1 PLL that I go today, too bad we got 25cm of snow yesterday and its going take a while to melt before I can on the roof.

Pyro:
Finally got the Titanium C1 PLL on, so far best out of all 3 lnbfs. Better signal strength across the arc, anywhere from 1-10% increase and it still locked the weaker transponders that the DMS got but the Geosat would miss.
