The Invacom adjustable feedhorn is designed for prime focus satellite dishes and LNB units equipped with a standard C120 flange. Its adjustable construction allows it to be matched to dishes with an F/D ratio from 0.32 to 0.43.
Correct adjustment helps the feedhorn illuminate the dish efficiently while reducing the amount of signal energy extending beyond the reflector’s edges. This can improve signal utilisation and reduce the reception of unwanted noise from the area surrounding the dish.
The feedhorn is a practical choice for professional and advanced satellite installations using a separate C120 flange LNB. It is particularly suitable for larger prime focus dishes where the feed system must be matched to the antenna geometry.

🔧 Installation and Adjustment
The feedhorn is attached to a compatible C120 flange LNB and positioned at the focal point of the prime focus dish. It is then adjusted to match the specified F/D ratio of the reflector.
For optimum reception, the feed position, focal distance, alignment and polarisation should also be fine-tuned using a suitable signal meter.
This product is intended only for compatible C120 flange LNBs and does not replace the LNB itself.
