There is disclosed a flexible fabric cover for an off-axis parabolic satellite antenna dish having a front surface which serves to cover and protect the front of the antenna dish and the receiver arm; the cover is preferably formed of a generally elliptical sheet of woven synthetic fabric which is at least moderately stretchable, which is about six inches greater in diameter than the antenna dishes it is intended to cover, and which has a central aperture or pocket for the antenna receiver support arm whereby the cover assumes a generally conical, slightly truncated shape; the cover includes securing means in the preferred embodiment consisting of a peripheral hem having threaded therein a drawstring or drawcord such that the cover may be placed over the front of the antenna dish with drawstring relaxed and the drawstring then tightened by employment of a conventional tightening device capturing the rim of the dish with the hem to fasten the cover tightly and smoothly over the dish and the receiver support arm. In one embodiment, the sheet comprises three sections generally in the shape of sectors of an ellipse with an angle of about 45 DEG and one section of generally rectangular shape positionable over the receiver support arm.
