Since this for a demonstration, why not use an RbO ? No antenna needed.

Hi all an interesting problem you may have encountered, I want to use
a GPS frequency standard inside a building with no opening windows
(opening windows are known as air conditioning in the UK :-)) )
This is part of a two day amateur microwave conference so we should
have the expertise.
I intend to try and pass the signal through a a double glazed glass
window unit (hopefully not metalised) using a couple of patch
antennas. The outer GPS antenna is active so will need a 5v supply
via an inserter. Inner patch active, outer patch passive to avoid
problems of feedback. Main antenna can be shielded from the "coupling"
either physically or with a slab of absorber.
Has anyone tried this?.... does it work?.....any gotchas?
Thanks
