Default Re: What is Unity Gain ?

The term Unity Gain means that your input and output are the same, or in unity. For instance, in audio, if your input is 1 dB and your output is 1 dB, you have unity gain. In the case of the Tram antenna, it neither adds or decreases gain on VHF. Hence, it has unity gain on VHF.
