It's harder to get as much gain out of a Yagi as you can out of a parabolic antenna.
Both a grid and Yagi can suffer from ice loading. A Yagi can be encased in a radome to eliminate that hazard. Most grids I've seen leak horribly. That is, they tend to spew RF out the back because of the grid spacing. They still have the forward gain, but spew to the rear. When world hams were preparing for the launch of P3D, a lot of experiments were going on in 2.4G because one of the transponders used that band. The front to back ratio issues were solved by covering the grid with a finer mesh. A Yagi, compared to the grid has a better front to back ratio, but has more pronounced side lobes and other minor lobes. I know you were asking about comparisons between a Yagi and a Grid. 2.4G, it depends on what you are doing. 5.8G, a solid dish with a radome wins every time; font to back ratio, side lobes, and the radome seals from ice, snow, hornets and decreases the wind load because of the Bernoulli effect. mg At 09:18 AM 12/11/2009, you wrote: >Any benefit of generally using a yagi over a wire grid or vice versa for a >CPE install? > > > >Robert West > >Just Micro Digital Services Inc. > >740-335-7020 > > > > > >-------------------------------------------------------------------------------- >WISPA Wants You!
