Triax "44cm elliptical" designation refers to the shape and size of the dish. Unlike a traditional circular dish, the elliptical shape is longer in one direction than the other. This can provide a more focused and precise signal for certain types of satellite transmissions. The 44cm size refers to the width of the dish across its longest point.

Satellite dishes work by capturing and focusing satellite signals from space onto a small receiver called an LNB (low-noise block). The LNB then amplifies and converts the signal to a form that can be processed by a satellite receiver, which is typically connected to a television or other display device.

To receive satellite broadcasts with this dish, it is necessary to align it correctly with the satellite that is transmitting the signal. This usually requires knowledge of the specific satellite being used and its orbital position, as well as access to specialized equipment for fine-tuning the dish's alignment.

Overall, the 44cm elliptical Zone 1 satellite dish is a relatively compact and affordable option for receiving satellite television broadcasts in many parts of Europe. However, its performance and signal quality may vary depending on factors such as the specific satellite being used, the strength of the signal, and the quality of the LNB and other associated equipment.
