WRT Antennas TE Connectivity / Linx Technologies WRT Antennas are ideally suited for applications such as wireless vending, security, traffic, or power equipment that require an unobtrusive, tamper-resistant antenna solution. The WRT Antennas feature a tiny 19mm x 11mm radome that 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. These WRT antennas also feature an integral counterpoise that eliminates the need for a proximity ground plane. The WRT Antennas are available in center frequencies of 868MHz, 916MHz, and 2.45GHz with coax feeds featuring SMA, RP-SMA, or custom terminations.
