I'm sure a FAQ, but a search on line did not resolve my question.

I need to feed my coax (QRP, 10 meters) out through a pane of glass, and
for that I need a through-glass coax coupler (this is not an automotive,
but a home window situation).

Most couplers are apparently capacitative. At 10 meters, for example,
would I gain much by going to a microstrip coupler instead (whatever
that is)?

How good a coupling can I expect with a through-glass coupler? It sounds
very lossy, but perhaps not.

What brands of couplers would you recommend, or what is a good source
for such couplers?

Hello,

Why not using inductive coupling? You can get reasonable coupling as
wires are just mm away from eachother, so you don't need high Q factor
circuit.
Matching indoor only is possible (so you don't need matching outside
to interface to 50 Ohm coaxial cable).
