Dipole ArraysS.M2E-160

2-stack lightweight dipole array, 145 - 175 MHz

Description

  • The S.M2 is an array of phased centre fed folded dipoles mounted on an aluminium mast for PMR / Trunked radio applications.
  • Each folded dipole balun assembly and associated harness junction is completely encapsulated in poyurethane resin, totally preventing moisture ingress.
  • At VHF the antenna disassembles and flat packs for ease of shipping.
  • Former Skymasts brand product.
