The Diamond F718 is a high-performance monoband base station antenna engineered specifically for dedicated operations on the 430MHz UHF amateur and commercial radio bands. Constructed as a rigid vertical array, this antenna features an advanced electrical layout consisting of eighteen 1/2 wave elements stacked inline. This configuration compresses the vertical radiation pattern to deliver an exceptionally high gain rating of 11.5dBi, significantly extending the effective transmission and reception boundaries for fixed base stations and repeater hubs.
Structurally, the antenna measures 4.60 meters in total vertical length, distributing its multi-element collinear array inside a heavy-duty weatherproof radome. Despite its substantial physical height, it maintains a lightweight profile of 1.7 kg to reduce mechanical stress on mounting masts and towers. The base section features an integrated low-loss N-Type female RF connector interface, ensuring maximum signal transfer efficiency and impedance matching across ultra-high frequency configurations.
