What size dish for COZI ?

[Andyboy90]

I have been considering getting back into Ku-band FTA. There is just not much content that I would be interested in nowadays. I can get two PBS affiliates and their sub-channels OTA. The only other FTA programming that I would be interested in is COZI which is not available in my area. Also, I have clear line-of-sight to 103 degrees while other sections of the arc are obstructed.
My EIRP from a small map linked from lyngsat seems to be about 48 db here in El Paso County, Texas. However I know there are many other factors involved in determining dish size. While I also realize that bigger is always better, the often recommended 90cm dish is very reasonable while 120cm would put a strain on my budget (not to mention my back).

I am a little late for this but i can easily get COZI on 103W with a 90cm dish in Northern Canada at the edge of 46db so you should be good with a 90cm dish.
