Just read a post in the general sat discussion where this person used a antenna in the attic, and a multi directional seawatch 20" marine antenna.[ seperate from the other, I believe] Picking up 40 or more channels at night. This is new to me. Can a marine antenna be that good? Why not use these for more OTA viewing? My antenna is also in the attic [ 3rd floor] and is just OK. It is positioned to pick up 75% of what is local. I have to move it to pick up the others, but then I lose the first 75%. Anybody know about these multidirectionals?
