Product Description
The WRT Series antenna is ideally suited for
applications such as wireless vending, security,
traffic, or power equipment which require an
unobtrusive, tamper-resistant antenna solution.
The tiny 19 x 11 mm radome installs through a
small hole on the product and is anchored by a
threaded base. An adhesive foam compression ring
is used to resist the elements. The ½-wave antenna
also features an integral counterpoise, which
eliminates the need for a proximity ground plane.
The antenna is suited for mounting in applications
where the counterpoise will not be shielded
from the antenna (non-conductive or open metal
enclosures); installation where the counterpoise is
within a shielded enclosure will affect the antenna
performance. The antenna’s coax feed is available
with SMA, RP-SMA, or a U.FL / MHF compatible
connector. U.FL and I-PEX MHF connector
standards are compatible with each other. Alternate
coax lengths, connectors and custom colors are
available for volume OEM customers.
