Can you recommend an external usb adapter with a good receiver, high
power output, external antenna connectivity and supporting the above
protocols.

Thanks for comments

At this moment in time wishful thinking on your part.

I have seen pre-n with removeable antennas but it would be unlikely for
these to be f'ware upgradeable to "N" when the standard is finalised.
There are "N" usb adapters with a single external antenna but they only
do 150Mbs and are not high power e.g.

power 19dBm 20MHz ch's and 16dBm 40MHz ch's
Buffalo are about to release the WLI-UC-G300HP which has a pop-up
antenna but is not removeable.
<http://www.buffalotech.com/products/wireless/nfiniti-wireless-n/nfiniti-wireless-n-high-power-compact-usb-20-adapter-wli-uc-g300hp/>
power 25dbm 20MHz ch's and 25dBm 40MHz ch's.

There are problems with the spacing between antennas for spatial
multiplexing to work to it's capability which is why you probably
haven't been able to find any adapters which will meet your request.
