Ok finally i have found the article about receiving a US-Satellite in Venezuela. It's published by Christian Mass (Chief-Editor of Tele Satellite International) in 9/1993 p.178/179 (in german)
19 dBW had to be received then from G-Star 93.5W
DH Satellite from Wisconsin made the job.
They set up 8 5m dishes. Each antenna was aligned with a spectrum analyser to a max. of signal. Then the 2nd dish was connected with the first and in right phase. Unfortunately it isn't described what they did exactly. But with 8 5m dishes the signal was still too weak, didn'T reach even the FM treshold. So another 8 5m dishes were installed. Then it was ok. So they avoided the not possible installation of a 40m (!!!) dish.
After that they tried the same in Wisconsin. But Brazilsat could not be received because strong signals from the neighbour satellite Spacenet (4° close to Brazilsat) made the reception of the wished sat impossible.
Ok this all only for C-Band. Upon that time they hadn't had any luck for KU-frequencies.
Since then i don't remember any article i have found for this.
I would advise to contact Christian Mass. As mentioned in the new issue of TSI he will travel in winter to Southern Brazil where Klaus Schumacher has built up his own 8m dish for receiving Astra 19.2 analogue and the Hotbirds on 13E also only analogue. Maybe he knows more about it.
Here's his mail:

P.S.: Maybe also in Namibia/South-Africa could be anyone who tried this since as far as i remember around 95-97 there was someone receiving Astra 19.2 analogue with a 12m dish.
