ERI is the Broadcast Master Distributor for HELIAX products, system components, and installation accessories.
HELIAX elliptical waveguide is the optimum choice for most microwave antenna feeder systems. HELIAX is precisionformed from corrugated high-conductivity copper and has an elliptical cross section. The corrugated wall gives the waveguide excellent crush strength, light weight and good flexibility for ease of handling. A rugged black polyethylene jacket provides protection during handling and installation. A full range of waveguide sizes is available for application from 1.7 to 26.5 GHz.
