I recently moved from the Atlanta metro area to the DC metro area and had the 5 LNB dish in Georgia. However, I'm worried the 5 LNB is too heavy to mount on the porch railing (I live on the 3rd floor), especially since the dish needs to be about 3 feet out from the railing to get signal. Right now, I have my old round dual-lnb dish and no HD except over the air and when I called D* about getting the 3LNB dish since it was lighter, the CSR informed me that the 3LNB dish does not received hi-def. programming? Is he right? Please help. Thanks.
