VHF Side Mounted Dipole, 130-150MHz, Unity Gain
The SMD20 Series side mounted dipoles are low PIM broad band antennas which, through different phasing and mounting arrangements can offer a variety of patterns (generally cardioid) tailored to specific coverage requirements. These antennas can be mounted in dual arrays for 3dB gain, or four-stack arrays for 6dB gain over a single dipole.

Features:
- Can be phased to provide 3 dBd or 6 dBd gain, in a variety of patterns tailored to suit specific requirements. An extensive range of phasing harnesses available.
- Full bandwidth coverage for both single antennas and phased arrays – ideal in community sites
- DC grounded for lightning protection and dissipation of static noise
- -150dBc Passive Intermodulation (PIM) rating
