Dish antenna symbol
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.

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.
A distinction that matters
The general antenna symbol has no reflector; the dish symbol shows the parabolic reflector.
