Model SMD-50 30 - 66 MHz. 3 dBd. Gain 
 

SIDE MOUNT DIPOLE

Design Features: The SMD-50 side mount dipole antenna is a robust antenna with low VSWR and high gain covering the entire band from 30-66 MHz. The side mount dipole antenna can be mounted on the side of a tower in vertical polarization with the help of supplied stainless steel mounting hardware. The SMD-50 side mount dipole antenna operates at D.C. ground for protection against lightning and immunity to noise.

Constructions: The SMD-50 side mount dipole consists of single folded dipole. The antenna maintains constant gain and VSWR over its bandwidth of 3%, making it highly suitable for single or multi-frequency systems. The N-Female antenna termination is fixed at a flying lead of RG-213 RF coaxial cable to ensures complete waterproofing and many years of maintenance free operation.
