S.H6-460
Omnidirectional dipole array, HPOL, 3 dBd, 450 - 470 MHz
Description
- The S.H6 is a stacked 6 dipole array configured as 2 tiers of 3 horizontally mounted dipoles on support arms which are welded to an aluminium support boom.
- The antenna has been specifically designed for UHF telemetry systems where use of horizontally polarized omnidirectional antennas are required.
- Each folded dipole assembly is fed via a fully encapsulated assembly and the integrated combining network assemblies are also fully encapsulated in epoxy resin, totally preventing moisture ingress.
- The overall design of the antenna combines an extremely uniform radiation pattern across the frequency range with low VSWR and reduced wind loading characteristics within a compact design.
- Former Skymasts brand product.
