I installed a slimline dish today but I'm only getting a signal on some satellites. On C (110) it has 95-98 on all transponders. On A (101) it has 80-85 but only on transponders 28,30, and 32. The remaining satellites have no signal. I replaced a 3 lnb satellite. Any suggestions? Is it just a matter of fine tuning perhaps? It got dark and I decided to wait until tomorrow to keep going. Thanks.
