Lookup label: SAT
Drawing use: GA, Schematic
Reference families: IEC

## Symbol convention

Convention: IEC
Form: Parabolic antenna
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Symbol for a parabolic dish antenna used for satellite reception or microwave links.

## In plain English

### What does Dish antenna mean?

A dish antenna is drawn as a curved reflector with a feed point and a support line. It is used on TV distribution drawings for satellite reception and on communication drawings for point-to-point microwave links.

### A simple example

Dish positions need line of sight to the satellite arc or the far end, and wind loading on the mount. The plan symbol therefore sits on site or roof plans with orientation notes. The symbol does not show the dish size or pointing angles, which come from the link design.

### What the drawings help you do

Check line of sight notes. Check mount and earthing. The general antenna symbol has no reflector; the dish symbol shows the parabolic reflector.

### This particular reference

Symbol for a parabolic dish antenna used for satellite reception or microwave links. The general antenna symbol has no reflector; the dish symbol shows the parabolic reflector.

### Terms

## What it represents

A dish antenna is drawn as a curved reflector with a feed point and a support line. It is used on TV distribution drawings for satellite reception and on communication drawings for point-to-point microwave links.
Dish positions need line of sight to the satellite arc or the far end, and wind loading on the mount. The plan symbol therefore sits on site or roof plans with orientation notes. The symbol does not show the dish size or pointing angles, which come from the link design.

## How to read it

- Check line of sight notes.
- Check mount and earthing.

## Information to show or reference

- State dish size.
- State pointing direction.
- Show feeder and LNB or radio unit.

## Important distinction

The general antenna symbol has no reflector; the dish symbol shows the parabolic reflector.

## Facts

- Graphic form: Curved reflector with feed
- Uses: Satellite TV, microwave links
- Exact standard graphic: Not reproduced here; confirm the form against IEC 60617 and the project legend
