A:Answer This TV has a ATSC / Clear QAM DTV (Digital Television) tuner. If by analog you mean over the air broadcast TV yes, you can plug in an antenna and get free television like other TVs. As far as differences between this KU6270 and the KU6300 they share many cool features including: HDR Premium (High-Dynamic Range), UHD Upscaling, WiFi, Ethernet, Digital Optical, 3 HDMI, 2 USB, Dolby Digital Plus (audio used by Netflix, Amazon, ATSC broadcasts, etc), Electronic Program Guide (Channel Guide).
The 6300 is an upgrade and adds features like Ultra Clear Panel, PurColor, DTS Premium Sound 5.1, and Composite and Component inputs (the older round red/white/yellow and red/green/blue inputs). 6270 is still an excellent TV and costs less.
