To make installation for your application easier, here’s a rundown of what to look for. First though, let’s decipher this: why use a Grid Antenna?

 

For point-to-point communications, a grid antenna has a lot of advantages that may make it the best choice for your application. First- since they are directional, they can provide better gain by focusing the beam in a particular direction. Second, though they are typically larger than other antenna types, they usually break down easily to fit in a box for easy transport to the installation site, or for storage while not being used.

 

Once assembled, the grid provides better wind loading than dish antennas. They are very also very easy to mount in either vertical or horizontal polarization and easy to tilt for precise aiming.

 

 

Assembly

 

We suggest double-checking the quality of the antenna before you purchase, especially if the installation is outdoors. The grid should have a UV protective coating and all of the hardware should be stainless steel.

 

When you order a grid antenna, it usually comes disassembled. Different manufacturers make grid antennas with slightly different installation instructions. When putting the grid antenna together, take all normal safety precautions to avoid coming into contact with dangerous electrical lines, etc., then go over the parts list. All grid antennas need the grid itself (often broken into two halves to reduce shipping costs), mounting "L" bracket, mast clamps, hardware such as screws, nuts and washers, and the feed horn. The feed horn is the long, protruding piece in the center of the grid that sends the actual signal. The below video (or this tutorial) demonstrates step by step assembly of the grid antenna.
