The Wavefield Toroidal T90 is a powerful dual-reflector, multi-focus satellite dish designed for receiving several orbital positions with a single antenna. It is ideal for international television services and installations combining satellites such as Thor, Astra 4.8° East, Hotbird and Astra 19.2° East.
Unlike a conventional dish with standard offset multifeed reception, the T90 uses both a main reflector and a secondary reflector. This design creates several effective focal points along the integrated LNB rail, allowing each LNB to be aligned with a separate orbital position.
The antenna is normally used for reception from up to six satellite positions. Under favourable reception conditions, as many as eight positions may be possible. Performance always depends on the installation location, satellite footprints, spacing between orbital positions and the selected LNBs.
Its large reflector surface and gain of more than 39.7 dB at 12.5 GHz provide excellent conditions for stable reception, including positions towards the outer ends of the rail. Five LNB holders are supplied with the basic antenna, and additional holders can be installed.

🛰️ Example Satellite Positions
Depending on installation location, clear line of sight and satellite footprints, the T90 may be used for positions such as:
- Thor 0.8° West
- Astra 4.8° East, formerly known as Sirius
- Eutelsat 9° East
- Hotbird 13° East
- Astra 19.2° East
- Astra 23.5° East
- Astra 28.2° East
- Other Ku-band satellites within the antenna’s adjustment range
The optimum combination must be assessed for the installation location. Satellite footprints and the distance from the antenna’s central focus affect reception performance.
🎯 Ideal For
- Households requiring channels from several countries
- International and multilingual television services
- Reception from several European orbital positions
- Astra, Hotbird, Thor and Astra 4.8°E installations
- Locations where several separate dishes are undesirable
- Fixed DiSEqC systems
- Houses, apartment buildings and commercial installations
- Advanced satellite systems requiring future expansion
🔧 Installation and Alignment
The Toroidal T90 is installed on a rigid mast with a diameter of up to approximately 60 mm. The antenna must be accurately adjusted for azimuth, elevation and rotation so that the selected satellite arc follows the LNB rail correctly.
Begin with a suitable central orbital position. Install the remaining LNBs along the rail and fine-tune each one individually for maximum signal quality. The polarisation angle, or skew, must also be adjusted separately for each LNB.
A compatible DiSEqC switch is used when several satellites are connected to one receiver. The receiver must then be configured with the correct DiSEqC port for each position.
The stated basic assembly time is approximately 45 minutes, although complete installation and precise alignment may take longer. A professional satellite meter is recommended, particularly when configuring many orbital positions.

⚠️ Important Information
- Reception depends on location, satellite footprints and an unobstructed line of sight.
- Up to six orbital positions represent a typical installation. Eight positions may work under favourable conditions but cannot be guaranteed everywhere.
- The maximum figure of 16 LNB holders describes the possible rail capacity and does not mean that 16 satellites can always be received.
- Only five LNB holders are supplied with the basic antenna.
- Additional holders must be purchased separately when installing more than five LNBs unless included with the selected package.
- Minimum spacing of approximately 3° requires suitable narrow LNBs and precise alignment.
- LNBs and DiSEqC switches are supplied only with packages that expressly include them.
- Circular-polarisation reception requires a compatible LNB or feed system.
- The antenna has no dedicated earthing connection. Earthing and equipotential bonding must comply with applicable regulations.
- The mast, wall bracket and mounting surface must be rated for the antenna’s weight and local wind loads.
- The stated critical wind speed is not a recommended normal operating speed or a guarantee covering the complete installation.
- The antenna’s large wind area requires an exceptionally rigid mounting structure.
- Professional installation and alignment are recommended.
- Technical changes and minor construction differences may occur.
