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 small 27 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 antenna
also features an integral counterpoise, which
reduces 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 or RP-SMA terminations. Alternate
coax lengths, connectors and custom colors are
available for volume OEM customers.
