MPR-2010BR comes with a circular polarized antenna to ensure reading tag with
random orientation. Most circular polarized antenna has a horizontal to vertical
differential of up to 3 dB, this will cause the antenna pattern to deviate from a true circle.
AWID s antenna has a horizontal to vertical differential of typically less than 0.5 dB,
making its pattern as near to a circle as possible.

Figure 3 - MPR 2010BR Antenna Pattern
· Antenna pattern measurements represent both horizontal and vertical polarized
planes of the read area transmitted by the reader.
· In the drawing above, R = approximately 12 feet to 15 feet for MPR-2010BR with
Alien free space tags.
· Antenna pattern can be affected by RFI and other environmental conditions.
4.2.3 Mounting Considerations
Antenna Mounting Bracket
Also available from AWID is an optional
antenna-mounting bracket (part # LRMB)
that provides antenna tilt adjustment and
pan adjustment. Photo at right shows
how the reader is mounted onto the
LRMB.
