== BUD: Big Ugly Dish ==A big ugly dish (often abbreviated to BUD) is a colloquial name for a satellite dish used to receive satellite television signals from FSS-type satellites on the C band. BUDs are usually about ten feet or three metres in diameter and have been a source of much consternation (even local zoning disputes) to neighbors of those with the dishes. Although some dishes are made of fiberglass, a common alternative is a metal mesh — such BUDs shed snow and suffer reduced wind loads; in addition, some critics consider them less unsightly.Recently, DBS services have reduced or eliminated the need for BUDs. Signals from DBS satellites (operating in the Ku band) are higher in power and therefore require smaller dishes than C band, and the digital signals now used require far less signal strength at the receiver. General advancements in noise abatement have also had an effect. For these reasons, significantly smaller dishes are now used for home satellite reception.A dual-band or Ku band LNB may be retrofitted to some big dishes, however there is a more restrictive maximum mesh size (anything less than the diameter of a pencil) if anything other than a solid dish is used at these shorter wavelengths. Usually, a solid fiberglass or spun aluminum dish is ideal for dual-band LNB operation.
