FPVCL-043-N
High-performance UHF left-hand circularly polarised (LHCP) prime focus feed
The FPVCL-043-N is a rugged, high-performance UHF left-hand circularly polarised (LHCP) prime focus feed, expertly engineered by Alaris mWAVE for operation in the 401–476 MHz frequency range. Specifically designed for integration with 3.8m diameter reflectors, this feed offers a self-supporting, vertex-mounted configuration that eliminates the need for external struts or guy wires—significantly reducing central blockage compared to traditional UHF feed designs. This low-blockage architecture results in enhanced antenna gain and improved sidelobe suppression, optimising overall system performance. A robust monopod structure supports the feed and includes a built-in ±3-inch focal axis adjustment to fine-tune feed positioning for optimal focus.

Specifications & Resources for FPVCL-043-N
- Design Features
- Built for exceptional durability, the FPVCL-043-N is fully weather-sealed and engineered to endure the harshest environmental conditions. It can withstand wind speeds of up to 125 mph (201 km/h), survive radial ice accumulation of up to 1 inch (25 mm), and operate reliably across a wide temperature range from -40°F to +140°F (-40°C to +60°C). Its robust construction also resists corrosion, making it ideal for deployment in coastal regions and heavily industrialised environments.
