Love the 20 dB receiver gain; just might obviate need to try coupling to the iMac antenna
(wonder if it's just a printed-ckt spiral or rubber ducky. Ha! an excuse to pull the back off.)
Nicer if it can be shielded, at least the back-180° attenuated without making bad reflections, VSWR mayhem.

Have to examine her router, see if it's got one of the shown RF-connectors; jeez, then I have to grok routers..
Beats running RG-8/U (?) in-air or trenched, though.

Thanks!
