- Page 2 A high gain Omni’s vertical radiation pattern will exhibit a flattened donut shape as shown below for the HG2415U-PRO antenna. Typical applications for Omni directional antennas include indoor office spaces, retail stores, warehouses, small office or home networks, outdoor cafés, campgrounds, RV parks and marinas.

Page 3: Directional Antennas
In the example above an Omni directional antenna is providing wireless connectivity for laptops, tablets, and smart phones in the coverage area. Directional Antennas A directional antenna, as the name implies, focuses the wireless signal in a specific direction resulting in a limited coverage area. - Page 4 In the example above building A and building B are set up for a directional, point to point network using Yagi antennas In this example both remote sites A and B have directional Wi-Fi connectivity to the base station fitted with an Omni directional antenna. This is an example of a point to multi-point set up.
- Page 5 Antenna Polarity Polarization refers to the orientation of the electric field component of an electromagnetic wave with respect to the Earth’s surface. An electromagnetic wave is composed of electric and magnetic fields propagating perpendicular to each other. Radio and light are examples of electromagnetic waves. Electromagnetic waves can propagate with linear, circular or elliptical polarization.
- Page 6 Antenna Gain Gain is a relative measure of an antennas ability to direct or concentrate radio frequency energy in a particular direction or pattern. Gain is typically measured in dB over Isotropic point source, dBi. The analogy of an Isotropic point source would be a sun in the center of a universe.
- Page 7 Path Loss Path Loss is an area of concern for 2.4 GHz wireless systems. Although 2.4 GHz signals pass rather well through walls, they have a tough time passing through trees. The main difference is the water content in each. Walls are very dry: trees contain high levels of moisture.
- Page 8 Outdoor Antenna Installation Best Practices When installing an antenna outdoors is it important to use the minimum cable length required between the antenna and the access point or enclosure connection point. Also make sure the cable enters the enclosure or device from the bottom and leave enough cable to make a drip loop so rain and moisture will not enter the enclosure or equipment connections.
- Page 9 Gain, Distance, and Loss Considerations When planning your wireless network you first need to define the distance between wireless links or between the access points or radios. A link budget will need to be done. First you need to know the characteristics of the radio equipment being used.
