The 414.04 Antenna is a version of the S.M4 four-stack dipole array, designed for improved performance in multi-channel communication systems such as TETRA.
The
antenna features four phased folded dipoles fed with an RG214 coaxial feed network which allows for beamtilt to be applied to the pattern; high quality materials and manufacturing techniques are employed throughout to ensure that the antenna meets strict intermodulation requirements of multi-channel systems. The balun housings and cable connections are completely encapsulated in an epoxy compound to IP67 eliminating any risk from water ingress. The antenna is supplied as standard with a 5 metre tail terminated with a 7/16 socket.
