The wingman definite improves digital signal. It doesn't say anything about HD. The complete Sensar says HD, but not clear on the Wingman add-on part.
Wingman
if we're talking about an over-the-air TV antenna then there is no such thing as an HD antenna or HD add-on. high def decoding takes place in the TV receiver. the antenna receives ALL tv signals.
the Wingman add-on is basically a UHF antenna. after the switch from analog to digital many TV stations which had frequency allocations in the VHF band changed their transmit frequencies to the UHF portion of the band. the wings of the Winegard antenna receive VHF frequencies while the center head contains the UHF antenna. the Wingman add-on adds another UHF antenna.
all TV signals are line-of-sight. if the transmitter antenna can't 'see' the receiving antenna you won't have a picture. in primary service areas almost any type of antenna will work. but the farther out from the transmitter you go the higher the receiving antenna needs to be. a lot also depends on the terrain in which the receiving antenna is located and what sort of obstacles are between the transmitter and receiving antennas (mountains, tall buildings, airport takeoff/landing patterns, etc.)
