If cost isn't an object, I'd order the ClearStream 2 Complete directly from Antennas Direct. When it arrives, disassemble the reflector assembly (it's held on with just screws and nuts) and discard (set aside) the reflector screen. Reassemble and install in a location that offers a good view in both of the directions of your primary signal. With the reflector screen removed, the C2V is a nice,compact, bidirectional antenna with 60-70 degree lobes both front and rear.
The "original" version of the C2V used screws and nuts to attach the reflector screen. The newest version that is available at Best Buy and certain Lowes stores uses rivets that would have to be drilled out making the modification less easy.
There are likely other antennas that would work just fine, it's just that this one comes to mind as a near-perfect fit for your application.
