After the reflector screen is removed from the 2 bay antenna and aimed at about 15 degree magnetic compass , the Tv station is still not received then install a
http://www.antennasdirect.com , CPA-19 preamp.
If the Tv station is still not received , then upgrade to a
http://www.antennacraft.net. U4000 with the reflector rods turned form the horizontal position to the vertical position to get the reflector rods out of the way so the U4000 can receive in two directions. This is simple to do , lift the clips that holds the rods in the horizontal position and rotate the rods to the vertical position.
The , >< , shaped metal elements are the reception elements. Now install the same CPA-19 preamp on to the U4000 that is aimed at about 15 degree magnetic compass. If the Tv station is still not received move the U4000 to above the roof.
