Winegard Sensar IV - reception symmetrical?
I just installed a Sensar IV and am very pleased with the significantly improved reception over the omni that came with the rig. We watch WESH 2 most frequently when we're not watching sat. TV. It'...

Ok, the old Winegard Sensar's were bi-directional, The pattern is what we call a figure 8 (there is a serious null off the ends of the wings) but reception is more oval like (I won't go into why but just ask you to trust me)
On VHF frequencies the new Sensar IV with as well as the older Sensars WITH the wingman, also exhibit this pattern (The wingman has no effect to speak of on VHF)
ON UHF the wingman points toward the target (Transmitter) though there is still SOME reception from the backside.. Just as there is off the sides... It is far reduced from what is in FRONT of the antenna.
And, by the way, thank you you have answered a question for me. (Does the Sensar IV have full 360 degree rotation?,,, NO).
There are a few folks who have modiied their Sensar antennas to get full 360 or better yet 370 degree rotation, Why Winegard did not design them that way I will never know.. But .. Well,,, They did not. Some day I'll fix mine.
