- 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 multichannel systems.
- The antenna is supplied as standard with a 5 metre tail terminated with a 7/16 socket. This model has a stronger boom to cope with high wind speeds.
- Former Skymasts brand product.
