The image is from the SG Labs website. I hope they don't mind me linking to it.
As you can see, this is small and light enough to be mounted on a portable mast close to a 23cm antenna to minimise cable losses.
As I could not find a price for this transverter on their website, I dropped them an email. I got a reply very quickly: 156 euros plus 8 euros economy shipping to the UK. They accept PayPal. Not bad for a 2W, sensitive, transverter. This is for V2.3 which also accepts an external 10MHz reference.
