Nice idea. I wonder how long those little u.fl connectors will last though.

IMHO, it would be cheaper and better to just get some chassis mount SMA
connectors and assemble something oneself. eBay item 183574973423 has 5 SMA
connectors at $2.80 delivered to the UK.

Working out the S-parameters
If you look at the cost of that board, it is *much* more expensive than far
more sophisticated PCBs available from China. To me at least, it seems a
relatively large amount of money for something that has very little
substance to it.
SDR-KITS sell a test board that seems to offer much more room for
experimentation at a better price.
