What would be the best way to track and loacte rouge radio signals around my house?

[Joeneedshelp1]

So if I wanted to locate and track down rouge radio/wifi/cell signals around my house, what would be the best way of going about it?  What kind of antenna should I use?  I was thinking of buying a Hackrf but waws curios if I could do so with just an antenna and a wifi adapter.  For instance if I wanted to track down a GPS tracker on my vechile?

for cell phone around your house you can use RTL-SDR 15$ with IMSI-CATCHER 

i already see some people who tracking car by sniffing IOT ex:( pressure tire ) with HACKRF

Best way to detect specifically a GPS tracker on a car is to get a GPS Tracker Detector (no joke.) It'll have a sensor that detects strong magnetic fields, because these are almost always attached to the underside of the car using a metal box with neodynium magnets. It will have an audible and/or visible alert when it detects a magnetic field. It will then have an RF detector for verification.
