Sorry. Haven't check this post in a long time. I think my antenna is a Channel Master. I will check this out this weekend and I will also post all the transponders signals at the best hour with a clear sky. I can tell you they are about 90 in the best ones and 60 for no weaker ones.

I'm also in Mexico City Hi jpr777! I'm also in Mexico City. I currently have 2 antenas. One 2.40m for 101° and one 1.80 for 119°. With the 2.40 antena I get on all trasponder you are currently reciving a signal above 80 but still could no get channels like TNT that it seems is in transponder...
