DIPOLE VS VERTICAL ANTENNAE
Dipole antennae should used to improve range and signal quality. This is
because vertical antennae receive RF signals from all directions, while dipole
antennae receive most RF signals from the front and back, eliminating noise
from the sides of the antenna.
Mounting Recommendations
1.
Mount the receiver as shown at the bottom. This will put the vertical
antenna in a horizontal position, which achieves the best range for the
Cansec SmartFob transmitter.
2.
Mount the receiver in a low electrical interference location.
3.
Mount the receiver in a location which optimizes a line of sight from the
transmitter.
4.
Vertical Antenna
: When using a vertical antenna, mount the SFR-200
receiver housing about 9 in (25 cm) away from the wall surface.
5.
Dipole Antenna
: The dipole antenna comes with an L-bracket for
proper antenna mounting. Connect a short piece (less than 25 ft or 8 m)
of 75 ohm coax (CATV cable and connectors) to the antenna and place
the receiver in a suitable location.
