Hi

Very new to this world.i have a technomate 5402 and a large motorised dish.i see there is a card slot on the reciever can i buy/aquire a card to put in here that allows me to view some scrambled feeds? is it complicated to understand? i like to watch tennis

Thanks

Debbie

Swing your large motorised dish over to 10° east and you will have plenty of Tennis feeds on there at the moment in HD and FTA
