Use your common sense! You are answering your own questions as you post. The question was is there a standard measure for bandwidth. I gave a couple of possible measures. This is not answering my own question. So, the FM antenna that is advertized as covering 87.5-108 mhz, what "Richard" wrote in message ... Hi. Is there a standard way to measure antenna bandwith? Is it within 3dB down of maximum gain, or is it between SWR limits? I'm looking at an FM receiving yagi that is advertised as covering the frequency range 87.5 - 108 Mhz. And I'm wondering what this means. Is the received signal going to be 3dB down at the band edges or what? I notice that there are commecial yagis (that are probably suitable for transmission) that have 150-174 Mhz in their description. Yet they are stated as having a bandwidth of say 1.3 Mhz. What's the deal here? |
