For the direction, try the tracking chart of lyngsat. On the map just click on your location and you will get all the azimuth and elevation angles.
With regard to the dish size, since you are on the fringes of the coverage **** print I assume you would need a fairly big dish for a good coverage, preferably 150cm or bigger.
Also during these days users in the middle east region have reported that the reception of DishTV and TataSky is very weak. I beleive this is due to solar interference which is inherent during March and April.
