I can pull in digital TV signals using a metal coat hanger........
Digital is all about the tuner in the TV NOT the antenna being used.
I have a small flat 8X10 RCA antenna on den wall for both TVs in house....but for the 5vr I'll use the Winegrad crank-up/rotating antenna because out in the toolies camping I need to AIM the antenna towards the towers to get a signal.
Something that is difficult to do using a flat mount antenna.
Just lucky that outside den room wall at home points towards transponder towers in my area.
Digital antennas.....great marketing but like majority of advertisements just a bunch of woo-ha
