a supplemental tuner that is separate from a primary tuner associated with the media device; the supplemental tuner selectively coupled to the multi-mode active antenna; and

one or more controllers configured to:

obtain data indicative of performance of the multi-mode active antenna in each of the plurality of modes while the supplemental tuner is coupled to the multi-mode active antenna;

determine one of the plurality of modes as a selected mode for the multi-mode active antenna based, at least in part, on the data indicative of performance of the multi-mode active antenna in each of the plurality of modes; and

configure the multi-mode active antenna in the selected mode.

2. The antenna system of claim 1 , wherein the one or more controllers are further configured to:

obtain data indicative of a geographical location of the antenna system; and

determine one of the plurality of modes as the selected mode for the multi-mode active antenna based, at least in part, on the data indicative of the geographical location of the antenna system.

3. The antenna system of claim 1 , wherein the one or more controllers are further configured to:

obtain data indicative of an orientation of the multi-mode active antenna from one or more motion sensors; and

determine one of the plurality of modes as the selected mode for the multi-mode active antenna based, at least in part, on the data indicative of the orientation of the multi-mode active antenna.

4. The antenna system of claim 1 , further comprising:

a switching device configured to selectively couple the supplemental tuner to the multi-mode active antenna.

5. The antenna system of claim 4 , wherein the switching device is movable between at least a first position and a second position to selectively couple the supplemental tuner to the multi-mode active antenna.

6. The antenna system of claim 5 , wherein:

when the switching device is in the first position, the supplemental tuner is coupled to the multi-mode active antenna and the primary tuner is decoupled from the multi-mode active antenna; and

when the switching device is in the second position, the primary tuner is coupled to the multi-mode active antenna and the supplemental tuner is decoupled from the multi-mode active antenna.

7. The antenna system of claim 4 , further comprising:

a low noise amplifier coupled between the switching device and the media device.

8. The antenna system of claim 1 , further comprising:

a demodulator coupled to the supplemental tuner, the demodulator configured to demodulate one or more signals received from the supplemental tuner.

9. The antenna system of claim 1 , wherein the media device comprises a television.

10. A method for configuring an antenna system for use with a media device, the antenna system comprising a multi-mode active antenna and a supplemental tuner that is separate from a primary tuner associated with the media device, the method comprising:

coupling the multi-mode active antenna to the supplemental tuner;

obtaining, by one or more controllers of the antenna system, data indicative of performance of the multi-mode active antenna in each of a plurality of modes associated with a ultra-high frequency (UHF) band or a very high frequency (VHF) band while the multi-mode active antenna is coupled to the supplemental tuner, each of the plurality of modes having a distinct radiation pattern;

determining, by the one or more controllers, one of the plurality of modes as a selected mode for the multi-mode active antenna based, at least in part, on the data indicative of performance of the multi-mode active antenna in each of the plurality of modes; and

configuring, by the one or more controllers, the multi-mode active antenna in the selected mode.

11. The method of claim 10 , further comprising:

determining, by the one or more controllers, an order for the plurality of modes based, at least in part, on a number of channels viewable when the multi-mode active antenna is configured in each of the plurality of modes.

12. The method of claim 10 , further comprising:

decoupling the multi-mode active antenna from the supplemental tuner.

13. The method of claim 12 , wherein decoupling the multi-mode active antenna from the supplemental tuner occurs subsequent to determining one of the plurality of modes as the selected mode for the multi-mode active antenna.

14. The method of claim 12 , wherein decoupling the multi-mode active antenna from the supplemental tuner occurs subsequent to obtaining the data indicative of performance of the multi-mode active antenna in each of the plurality of modes.

15. The method of claim 12 , further comprising:

coupling the multi-mode active antenna to the primary tuner occurs subsequent to decoupling the multi-mode active antenna from the supplemental tuner.

16. The method of claim 10 , wherein coupling the multi-mode active antenna to the supplemental tuner comprises coupling the multi-mode active antenna to the supplemental tuner via a switching device of the antenna system.

17. The method of claim 10 , further comprising:

obtaining, by the one or more controllers of the antenna system, data indicative of a channel selection.

18. The method of claim 17 , wherein coupling the multi-mode active antenna to the supplemental tuner occurs in response to obtaining the data indicative of the channel selection.
