how to find out more about smart antenna

I have one of the RCA Digital TV converter to analog set top box.

I bought this at Walmart.

In the back of this STB, there is two antenna inputs.

One is the regular BNA coaxial one pin (with ground) input.

The other is labeled “Smart Antenna”. This is a 6 pin receptacle like the Ethernet or phone jack connector.

Can you please tell me where to find out more info about this Smart Antenna. Or, may be buy one? Thank you.

Try Googling “rca digital converter smart antenna”. Apparently these are antennas that can be used in high signal strength areas to address multipath issues. In the analog days, multipath expressed itself as ghosting. These antennas can be electronically rotated and have adjustable gain settings.

well, if you google that, you will find my previous post asking the same question in the AVSForum. LOL.

In fact, I even called and email RCA and gotten response with do not know answer.

It would be nice if there is a good smart antenna we can use to get better reception for our terrestrial digital TV set, instead of heavy reliance of cable TV. In fact, just so we can get digital terrestrial digital TV through cable, we have to pay more. Yuck.
