I just bought a CM 4221 antenna and Spartan 3 preamp (3041) to help me pick up some OTA HD channels with my Dish Network 722 DVR. I plan to mount the antenna in the attic, but have some questions about where to put the preamp. Most advice I have read is to mount the preamp to the mast below the antenna, but I will not have a mast. In fact, the antenna just barely fits in my short attic. So, where should I put the preamp? I can mount it to a nearby rafter, but does it matter if it is in front of or behind the antenna? I could mount it the the very bottom of the antenna, but is that too close? Should I route the twin-lead through the screen to place the preamp behind the antenna? Or just let the wire go in front of the antenna and off to the side?
