This is a BATWING with the dipoles added...

This is the KING antenna which is becoming popular with the manufacturers now...

We have great luck using the OTA BATWING antenna picking up the NATL Digital OTA HDTV from the local towns. Sometimes becomes a bit tasking getting the OTA signals scanned into the TV but once they get logged in they are perfect high def TV signals or nothing at all...
If you have the LED lights try turning them off when this occurs. Also the roof fan motor may cause this at times..
Also these antennas shown above can pick the HDTV signals in both directions. They do it best if the antenna pointed at the transmitting station. Make sure you are pointing in the right direction. The BATWING SHOWN ABOVE is pointing to the right. The first JACK antenna is pointing to the right - the second picture is pointing to the top.
