RFI UHF Side Mounted Dipole 400-520MHz

  • Tuned to full bandwidth
  • Unity gain
  • All welded, full folded dipole construction
  • Easily mounted and installed with single clamps
The SMD4-67 is of all welded aluminium construction. The feed point is protected by an ABS cap, with the internal PTFE based cable construction providing excellent intermodulation performance (-150dBc). The stainless steel SMD41-67 is electrically identical to its aluminium counterpart and is recommended for corrosive environments, this antenna is available on request. All of the SMD4 series antennas are directly DC grounded for superior lightning protection and the reduction of precipitation static noise.
