What are the differences between an Omni antenna, Panel antenna, Parabolic antenna, Sectors antenna, and the Yagi antenna’s?
Antenna differences: An Omni antenna is omnidirectional. In other words, the signal is transmitted and received equally in all directions. (Ignoring such influences as trees, terrain, large buildings, etc.) Panel antennae, Parabolic antennae, Sectors antennae, and the Yagi antennae are all directional antennae. They all have different applications, which is highly dependant on the particular setup. For example: A Sector antenna is usually design to cover a wide pie shaped area. The width of the sector they cover typically ranges from 60° to 180°. Usually they are used to provide specific regional coverage for broadcast areas of WISPs (Wireless Internet Service Providers) or similar applications. Q: What is all this talk about dB and deciBels. I thought radio power is expressed in Watts? Q: Why are deciBels expressed in negative numbers in NetStumbler? Q: Why doesn’t SNR equal Signal/Noise? A: Decibels (or dB) is a REFERENCE value only. You have to reference it to a known value such as
