Antenna Experts manufacture SMD series omni-directional side mount dipole antenna for 30-66MHz, 75MHz (66-88MHz), 150MHz (134-174MHz), 250MHz (220-290MHz) 350MHz (300-400MHz), and 450MHz (406-512MHz) frequency bands with 3 dBd, omni-directional. gain. The SMD series VHF/UHF exposed open dipoles are designed where omni directional coverage required with moderate gain.

The SMD series heavy duty side mount dipole features, wide bandwidth, moderate gain, high power handling capacity, low VSWR, low noise performance with omni directional characteristics which are highly suitable for TETRA and SCADA applications.

These SMD series side mount dipole antenna maintains constant gain and VSWR over its specified bandwidth, making it highly suitable as base station antennas for repeater, paging and any other multi-channel communication systems. All the SMD series side mount dipole operates at D.C. ground for protection against lightning. Powder coating of the complete antenna provides extra protection against corrosion in saline weather present in coastal areas.

The side mount dipole antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum and designed for vertical polarized waves. The center fed dipole ends and cable connections to the dipoles are sealed in epoxy at the end of the boom for protection against weather and imparting rigidity and strength to the dipoles structure. All the fasteners are made of marine grade SS. The central mast for mounting the dipole is also supplied with the antenna. The dipoles are mounted on a tubular boom made of high strength aluminum alloy, which offers a low resistance discharge path against any lightning strike during the stormy weather. The N-Female termination of antenna sealed in flame retardant heat shrinking tube ensures complete waterproofing.

These SMD series Side Mount Dipole Antenna are a robust antennas with low VSWR and high gain covering the entire band from 30-512 MHz. The side mount folded dipole antenna uses 6063T6 ultra corrosion resistant architectural aluminum alloy which makes these SMD Series side mount folded dipole antenna to withstand the severe environmental conditions. The N-Female antenna termination of side mount folded dipole antenna is fixed at a flying lead of RG-213 RF coaxial cable to ensure complete waterproofing and many years of maintenance free operation.

The SMD series Side Mount Dipole Antenna operates at D.C. ground for protection against lightning and immunity to noise. All SMD series side mount dipole antenna offer wide azimuth and elevation beamwidth which provides excellent null fill for consistent signal coverage. The balun and the dipole connection of side mount folded dipole dipole antennas are sealed in epoxy to make sure complete waterproofing of the side mount folded dipole antenna. The antenna can be supplied without central mast optionally.

All our SMD series omni antennas are marine variant. Support pipe of fiberglass collinear antennas is made of 6063T6 ultra corrosion resistant architectural anodized aluminum alloy. Mounting hardware fiberglass collinear antenna is made of type 316 marine grade stainless steel. All these features make our fiber glass collinear antennas highly suitable for marine environment.

Antenna Experts offers side mount dipole antenna for 30-66MHz, 66-88MHz, 136-174MHz and 330-512MHz bands. Apart from these frequency bands we are experts to design and supply the side mount dipole antennas for out of these bands.
