WebApr 8, 2024 · For outdoor purposes, it’s usually better to buy a low gain antenna for the best coverage. They have more of a round-shaped signal pattern, which will radiate the WiFi signal closer to the ground. A high gain antenna might stretch the signal out too far, causing the signal to be better further away and weaker within your backyard. WebFeb 10, 2024 · The study shows that you will need earth station antenna gains of around 15, 24, and 38 dBi, respectively, to support a link margin of 6 dB. A typical discone antenna (e.g. 118-3000 MHz scanner antenna) will have a gain of less than 5 dBi, so you would end up with negative link margin (i.e. the link will fail). Share.
