GPS Antenna Enclosures

GPS receivers depend on unobstructed satellite visibility across the entire sky hemisphere for optimal performance. To preserve signal quality, radome covers employ RF-transparent polycarbonate or fiberglass materials that pass L1, L2, and L5 frequencies. These materials resist UV degradation while maintaining low insertion loss over years of outdoor exposure. 

Antenna positioning within the enclosure centers the element beneath the radome apex, maximizing sky view without structural obstructions. Low-noise amplifiers mount directly at antenna terminals, boosting weak satellite signals before cable losses degrade signal-to-noise ratios. Beyond RF considerations, lightning arrestors divert transient voltage surges to ground before reaching sensitive timing equipment housed in equipment shelters below.
