I work for a coffee supplier to 8the tv stations a d have spoken to some of the engineeers about hd and digital reception. A high 90%they of signals nationwide are now on uhf. A few channels are on the vhf high 7 to 13. For best reception you need a uhf antenna. You also need a uhf signal booster most older ones and amazingly enough most sold jn stores to this day are vhs only. To use a southern expression useful as a fifth teet on a boar hog. There are many good uhf antennas for less than $30 at places like radioshack. Remember these are directional antennas and will need to be rotated for best reception. Penty of $30 antennas out there being sold for over $100 claiming to be special hd tv antennas. Great marmstting bs.
