I did a Google search about 8 months ago, and I found what seemed to be an ideal liquid to use for this purpose. I forget what it was, but it had a low dissipation factor at HF and a good dielectric constant. I don't think that it was an oil. I searched this morning for something like "dielectric constants and dissipation factors of liquids", but I couldn't find it. 73, Mike www.w0btu.com _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
