Hello folks,
I, too, have noticed significant insertion losses with diplexers, some devices significantly worse than others. I am currently using Diowa diplexers for both my TS-2000 and IC-910, they the best of several I have tried. Nonetheless, compared to direct connection, they are lossy, no question. If anyone knows of available diplexers with which there is genuinely very low loss, please post your info. I, for one, would be glad to find something that does not attenuate signals, especially weak ones.

That seems awful high to me. My duplexer the loss is not even noticeable on
receive.
