Antenna feed (or it is also called like feedhorn or feed horn is possible) is one of the main part of a parabolic antenna (satellite dish) located either in its focus (phase center, if considering axial feed) or out of focus (if considering offset feed) or focal plane, which forms the radiation pattern and polarization of the antenna.
Antenna axial feed is a small horn antenna which is used to convey radio waves between the BUC and/or LNB and the dish (parabolic reflector). In directed antennas the feed is connected to the BUC (block up converter or transmitter) and converts the radio frequency alternating current from the transmitter to radio waves and feeds them to the rest of the antenna which focuses them into a beam.
Our antennas are always supplied with our feeds in a kit. Radiation pattern of the feed, its VSWR, band and other parameters correspond to all our antennas, to their parameters, developing in one technological process. So buying our antennas and using our feeds you obtain absolutely matched system.
Axial Feed is a precision-engineered antenna feedhorn designed for parabolic dish antennas and satellite communication systems. As the core component of a satellite dish, the Axial Feed is positioned at the focus (phase center) of the reflector, forming the radiation pattern, stabilizing polarization and ensuring optimal RF coupling. This universal axial feed supports efficient transmission between the dish and LNB or BUC, providing minimal reflection losses and clean signal performance across broadband RF applications.
Engineered for compatibility with a wide range of BUC and LNB units, the Axial Feed operates as a high-efficiency interface that converts RF current into radiated energy and directs it toward the parabolic reflector. Its low-loss geometry, broadband capability and stable impedance make it ideal for uplink/downlink systems, satellite tracking terminals and professional communication installations. Designed within a unified manufacturing process, the feed integrates perfectly with parabolic dishes, forming a fully matched antenna system.
✅ Precision-engineered axial RF feed system
This axial feed provides optimized beamwidth, superior gain uniformity and accurate polarization alignment. Its geometry ensures maximum energy transfer between the RF chain and the reflector, maintaining low VSWR and high signal purity.
✅ Ideal coupling to LNB and BUC units
The feedhorn ensures stable and efficient RF transmission, supporting high-power uplink BUCs and sensitive LNB front-ends. Matched impedance reduces reflections and guarantees smooth operation in professional satellite communication systems.
✅ Unified design for matched antenna systems
Developed as part of a unified antenna manufacturing process, each axial feed is fully compatible with parabolic dish reflectors. This ensures consistent performance, matched phase characteristics and minimized error across the entire RF front end.
🛠️ The Axial Feed is designed for reliable RF integration and acts as a precise transition point between coaxial or waveguide components and the parabolic reflector, maintaining optimal phase alignment and maximizing antenna gain. Its robust structure ensures dependable operation in ground-station and outdoor environments.
🛒 The Axial Feed is an excellent choice for professional satellite systems where engineers and integrators require a well-matched, broadband and low-loss feed system. It enhances the efficiency of dish-based RF terminals and delivers superior reliability for satellite communication, telemetry and broadband data links.
