ADVERTS
The strongest sat chl on 43W Intelsat 11 is 3985V 1200 FEC3/4 for the Netherlands. However signal is weak (S67-69 on my Coolsat 4000)here in Ft Lauderdale that have a stronger foot print for my 6 foot dish. I cannot lock 3928H 13500 FEC 7/8 if that is what you are trying to get. Using my 6 footer I need higher signals for 7/8 FEC. usually S75 and above.
I'm currently viewing 40.5W and transponders with lower sig levels(less than S70) with FEC 7/8 will show, because of the circular polirization( using DMX741U w/insert). However linear signals I noticed need a higher Q for 7/8 FEC.(S75 and higher).
I clearly see why a bigger dish is needed for FEC 7/8. if the footprint is not strong and it being a linear sat. I experienced same issues with 55.5W trying to get 3940H FEC7/8 Cool TV (Mexico Travel Channel) which is a much stronger satellite.

Thanks, nycrich for all the info. I remeber S 67-69 is the minimum on Coolsat for 3/4 FEC signals, therefore I will aim the Dish at another bird then, since the 7/8 televisa signal was my main target and unlike you I am way up north here in Toronto. Besides I have a tree, without leaves now, in the way. Will try the circular 40.5W (also behind the same tree, yes I am masochist, lol) just for comparison and fun.

You should be able to get all the unscrabled signals on 40.5W. I have my 6 ft Fortec Polar mount tempoary pointing there. The strongest sig for pointing is 3803L 27500 3/4. There are some tp with 7/8 that will take a little while lock but you will be able to view it. There is less than 5 tp that I cannot get (3658R, 3746L, 3749L, 3982L, 4146L). Again I can get everything else, including scrambled(of couse I cannot view it, but for sig purposes). Surprisingly I can get MPEG-4 (3964R & 3966R) which registers the highest tp for the sat. However I would not try those yet until you lock MPEG2 sigs before.

The issue is not as much the signal seems lower its the adjacent satellite signals from the neighboring satellites that the 6' is seeing. The smaller the dish=more skyband wider beamwidth it has at a given frequency. A 6 ' dish sees 3 degrees of sky. Satellites are 2 degrees apart. You are getting unwanted noise from the other sats and it affects the high fec's first since there is less compensation for lost data with a high noise floor.
A 6' dish is an extraordinary ku dish but falls short on c band to some degree.
