After many years in Ku band(of course analog too) , this year I decided to "play" with C band too.
At the begining of summer I got a very good quality Al 150 cm PFA dish with f/d ratio of 0,42 .My dish has a good homemade polarmount and a 18" HARL actuator(as in photo).I can receive satellites between 93,5East -22West with this system!I also like to make depolarizer plates for (L,R) in C band of course.During outdoor testing I use an HOHER portable DVD player with A/V in and a Kaon 570 receiver .In the photo you can see Ariana afgan television from 93,5East, outdoor picture!An MTI 15 kelvin C-band LNB is my favourite now,after certain tests .
For blindscan I use Vantage X201
I upload some picture with the dish pointed on several satellites.My favourite C band sats are: 90E, 83E, 64E, 49E, 5W, 22W.
Now I work on a pretty cool 1,8m PFA dish.Soon I'll upload some photos
I noticed that some C band freaks are interested in my dielectric plate
I upload a schematic of it.I recommend to use aluminium foil from chocolate .This proved to perform very well among other Al foils...
Use only transparent plastic , the 1 mm thick one is the best in my tests.Everything between 0,5-1MM is good
The width of the alu stripes must be 3,5-4mm .Please respect the dimensions
The distance betwwen stripes is 5-6mm The big stripes(3 on the center) 10mm width are very important for the reception.
You can modify a little bit the dimensions and notice signal increases on certain channels
...Go further and put perpendiculary 1mm thick cooper wire spiral (4-5 little spirals) an the each side and you'll notice real frequency cuts and strong amplification one other freq.A lot of play with
