SKU: SMD4-67-U Category:

The SMD series of side mount dipole antennas are an extremely broad bandwidth antenna recommended for local area coverage or short haul RF link applications.

The SMD series are all welded aluminum construction. The feed point is protected by an ABS cap, with the internal PTFE based cable construction providing excellent intermodulation performance (-150dBc).

The antenna is internally DC grounded for lightning protection and the reduction of precipitation static noise.
