SMC 500 / SMC 1000
Side-Mounting Brackets for Base Station Antennas
DESCRIPTION
These side-mounting brackets are used when a base station antenna
has to be side-mounted on the supporting lattice mast or mast tube.
The SMC 500 has a side-mounting distance of approx. 0.5 m and the
SMC 1000 a side-mounting distance of approx. 1.0 m.
Both types can be supplied with U-bolts either for masts with diameter
15 – 65 mm (typical: lattice mast legs) or for mast tubes with diameter
between 65 and 105 mm. (See table below).
The brackets are mainly intended for all the omnidirectional antennas
provided with type “C” or “LW” clamp, but can also readily be used
together with all “GP”-antennas for 38 mm mast tubes or for carrying
directional antennas.
The brackets are made of hot-dipped galvanized steel and all
accompanying fittings are in stainless steel.

PLEASE NOTE
The optimum position for an omnidirectional antenna is at the top of the
mast as this ensures undisturbed radiation in all horizontal directions.
Mounting of an omnidirectional antenna at the side of a mast imposes some
distortion of the radiation pattern as well as the SWR. The influence is
dependent on the distance to the mast and the mast diameter.
Often this effect can be advantageously exploited to create directional
patterns when a certain “preferred area” has to be covered by the antenna
system.
