Hello!
the signal on this transponder is very strong here!
i would say also 60 cm is enough!
i have declination of only 12.5 degree,the last satellite in the east i can receive,then the mauntain comes,and blocks every thing!
the old sabc channels,swtiched off 2 years ago,because nagravision was hacked!
to check,on your location,is there a free view to the satellite you want to receive,i found a real great site on _dishpointer.com
google earth and the nesersary browser plug in must be installed!
you can create a high profil!
just enter your streetname,and the place where you leave in the above line,select the satellite, mark it in the corner under the earth sign,then you can zoom in and out in all direction,
you see how high the mauntain is,the distance,from it!
this programm does not affect tres or houses!!
very nice to play withit!
with this programm you can find on what places is it posible to receive the satellite,i callculate,that i have to move from 800 m to 1500 m sealevel and found one little place,with this programm,where it would be posible to receive more eastern satellites like thaicom!
works worldwide,in the beginning it needs a lot of time to adjust!
and not all photographics are in a good quality depent on the location!
