For those wanting to try an outdoor antenna for better reception, there's no need to drill a hole in your wall or leave a wire hanging through an open window. I recently discovered this nifty little gadget that I never even knew existed.
This is "
Ghost Wire Flat RG6 Coax Jumper Cable Extreme Slim Flat Window Cable". You can put it in a window sill, close it completely, lock it, and you're good to go. It costs about $10 at Amazon. I recommend using quad-shield RG6 to connect to this gadget to your outdoor antenna.
To connect your SDR to the ghost wire, I recommend something like "
SMA to F Adapter SMA Male to F Type Male RF Coaxial Connector Cable Extension" also at Amazon for about $8. Its important to have an adapter with a wire between the ends. Otherwise, undue stress might be put on the SDR's connector and could possibly damage it.
I hope you found this post helpful. Good luck and have fun with your SDR.
Edit: having an external antenna improved my reception significantly.
