Does anyone know what this refers to??? This is typically a pretty high number 10 -> 30 db. -- David; /archives//html/VHFcontesting/2005-04/msg00024.html (7,233 bytes)

The higher the number - the closer to a 1:1 SWR you are seeing.

You mean power reflected across the T or from the T. If it is from the T then wouldn't that be bad? If it is across the T the wouldn't 10 -> 30db be bad also? -- David L.

Put a directional wattmeter on the input and put some power through it. The return loss is essentially the difference between the inp; /archives//html/VHFcontesting/2005-04/msg00027.html (8,239 bytes)

Re: [VHFcontesting] Biat Tee return loss (score: 1): Author: "KA6AMD" <ka6amd@earthlink.net>; Date: Tue, 12 Apr 2005 18:08:39 -0700; Hello David, The return loss spec is the essentially the SWR of the bias tee. This is a measure of the mismatch of the bias tee with the transmission line you are using. 10 dB means that the reflecti; /archives//html/VHFcontesting/2005-04/msg00034.html (8,671 bytes)
