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.
