Rico,
I had used either Comet or Diamond diplexers in the past, until I found the MFJ diplexers were about half the price of the Comet and Diamond units, with what I saw as comparable performance. WiMo in the US is like your description of MFJ in Europe; I've never seen or tried WiMo diplexers.
One review I saw a while back actually showed the MFJ-916B to be much better than Diamond's MX-72:

The pictures and screenshots aren't in this article, but the text tells the story of this comparison.
73!

Hi all,
I'm using an FT-897D for TX (non-duplex), and an Airspy and computer for RX. Good idea to use four switches Greg, in fact that's what I'm currently doing. With four switches you always use one antenna for RX and the other for TX though, I want to be able to use the same antenna for RX and TX when that works better with the current satellite orientation. Using two switches and two diplexers I would be able to independently select which antenna to use for RX, and which one to use for TX. I posted the connection scheme on twitter (warning, mspaint ahead): https://twitter.com/PA3RVG/status/950649511935905792
But we are drifting from the original question: which diplexers? I have heard good stories about the MFJ-916, but its availability is not great in Europe. What about Comet, Diamond or Wimo? Are they any good?
