Now it's easier to meet your transmission line loss requirements and remain within budget with a new 5/8" foam-dielectric cable. Heliax cable simplifies system design by offering another alternative when balancing perfomance and cost. LDF 4.5-50 cable may serve as the main transmission line solution for applications where cost effectiveness is the primary concern. |
