PMB Series antennas combine a soft blade-type
element with a rugged package that is resistant to
damage and abuse. The antenna features a molded tab
that allows coding of the product’s enclosure to control
360-degree rotational travel. The PMB mounts to a PCB
via one or two screws and meets Part 15 requirements.

Polar Plot & Gain Information
Monopole antenna gain and radiation patterns are dependant on
the ground plane and layout of the end product. Since antenna
manufacturers do not measure on standardized ground
references, comparison of published specifications is an
unreliable indication of actual antenna performance in an end
product. Optimum full-wave ground planes are impractical for the
majority of products on which these antennas are used (the
ground plane for 916MHz would be 26.5" in diameter, 418MHz
would be 56.5" in diameter). For this reason, Antenna Factor tests
and tunes antennas on reduced-size, compromised ground
planes. To avoid mis-comparison or inappropriate application,
gain and polar plots do not appear on this data sheet, but are
available upon request for most products.
