Client Antenna Gain is the normal dBi of the antennas you use. If you are looking to create a map with the maximum coverage area you will need to enter your largest receiving radio’s values here. If you want to standardize based on the normal radio you normally use, not the largest you can use, your coverage will be smaller. This is a technical decision on what you want your coverage map to show. Again, if you want the maximum coverage, then you would enter the largest value that you would actually use in the antenna gain field. For WISP operations, we would recommend to put the largest antenna that you allow your installers to install with to show you the maximum coverage area.
