Anyone use this type of OTA TV antenna?

This antenna seems to be something that Roadtrek uses. It is similar to a Jack antenna where it doesn't need to be raised or lowered, but it is omnidirectional, so one doesn't even need to turn a knob until the number of LEDs maxes out.

The same company also sells 12 volt LED TVs and TV/DVD combos of various sizes.

Has anyone used this? If it gets near the reception of a batwing antenna, it would be a no-brainer of an upgrade.
