Antennas - 900 MHz Band Antennas

Indoor Mount Vertical Whip Antenna

This indoor mount vertical whip antenna is designed for short range work. It has a gain of 2.1 dBi and a radiation pattern shaped like a horizontal donut.

A swivel joint at the bottom allows it to be mounted on a vertical or horizontal surface. It mounts by screwing on to a Reverse Polarity SMA female connector.

Omni Directional Vertical Antenna

These vertical antennas also have a radiation pattern shaped like a horizontal donut, but have a higher gain and are designed for outdoor use. They are useful for a master antenna in a polling system where the control transmitter and receiver must send and receive to several slave units dispersed over a broad azimuth angle.

Yagi Antenna

Yagi antennas achieve more gain than verticals by concentrating radiation in a single direction. Their reduced gain from the back end helps keep other signals from interfering with normal operation. The front to back ratio is an important characteristic of a yagi antenna.

A yagi antenna can be operated with the elements mounted vertically or horizontally. The most common use for industrial wireless is vertical. The transmitting and receiving antenna must both have the same element polarization for satisfactory operation. A large loss in signal is experienced when the elements are crossed polarized. This characteristic can be used to reduce or eliminate interference between systems.

When a vertical omnidirectional antenna is used on the control end of a polling system, a vertically polarized yagi can be used on each slave unit for maximum gain and reduction in interference due to the front to back ratio gain reduction characteristic of the yagi.

Parabolic Antenna

The Parabolic Antenna can only receive signals from the front. It is the antenna of choice for long range work or in areas of potentially high interference.
