You can use any kind of antenna which is compatible with your SDR dongle. Most of them come with a female SMA input which is the most commonly used connector (with BNC) for audio oriented RF receiver. You can even connect your dongle to any RF distributor like the ones from BSRF, Sennheiser or PSC... Make sure not to overload the antenna input of your SDR USB dongle (check your dongle specifications) !
