It is true that the HD1200 antenna reception elements are longer at the back of the antenna and the antenna is wider at the back of the antenna because of the longer reception elements.
The longer reception elements are designed to receive channels 2 thru 6 and FM radio.
The HD1200 antenna provides the flexibility to receive the VHF low band channels 2 thu 6 and FM radio frequencies.
And the longer reception elements at the back of the HD1200 antenna act as reflectors to increase the forward gain and direction ability of reception of the shorter of length 7 thru 13 reception elements.
This forward gain and sharper forward reception , helps reject multi-path/reflected signals that bounce off the surrounding mountains and buildings and interfere with reception of channels 7 thru 13.
(channels 7 thru 13 are more supseptable to the disruptive effects of multi-path/reflections)
I recommend install the HD1200 All channel antenna.
