Although not wireless, I had the idea of using a USB to ethernet device.
That is, the dongle plugged into the device and accessed over ethernet.
If it were possible, it would put the dongle right where it is best, at or very close to the antenna = nearly no cable/signal loss.
In theory, you could now have the dongle up to 100 yards/metres from your network switch/router and no signal loss.
Imagine having an antenna/dongle at some remote site with enviable reception (and internet connectivity) and you access it from afar.
I tried with a TP-Link TL-PS310U

Using Windows 7, I can get an RTL-SDR dongle to be presented to the system, unfortunately, even using Zadig to add the correct driver, SDR# RTL1090 etc cannot access it even though Windows device manager ‘sees’ it as the correct USB device.
I haven’t tried with Linux and a GUI, let alone command line only but on the TP-Link site, it shows how to access the device and add a printer attached to the TL-PS310U.
I see on the TP-Link website, they may offer source code for the TL-PS310U, but I’m now way out of my league.
An email to GPL@tp-link.com might yield something useful if anyone is brave enough to take it on
