Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks. Note that by using the band from 3.7 to 4.0 GHz, this C-band overlaps somewhat into the IEEE S-band for radars.
A ventral hernia occurs when a weak spot in the abdomen enables abdominal tissue or an organ (such as an intestine) to protrude through a cavity muscle area. These hernias are visibly identified by a bulge in the belly area. The most common sites for ventral hernias are the site of a previous abdominal procedure (an incisional hernia), the navel (an umbilical hernia), and the groin (an inguinal hernia). About 90,000 ventral hernia repairs are performed in the United States each year.
1 Incisional hernia can occur through a scar if you have had abdominal surgery in the past.  Umbilical hernia is a bulge around the belly button. It occurs when the muscle around the belly button does not close completely after birth.
