Wow, thanks for all the speedy responses! Unfortunately I am a bit stupid about much of this and am somewhat confused. I have my antenna aimed at around 139 deg. and that is about where I had the old one. My old one actually worked pretty good but I hoped I could make it better so I decided to open this can of worms.
StephanieS you are correct as to what my goals are (I think) as wanting a modern preamp but not knowing what one. Also I don't know how you tell channel 11 is VHF by the chart. It has always came in pretty good so I assumed it was UHF. Also I get a bit confused also matching the channels from my tv together with the radar chart.
I just did a channel scan and currently I am getting channels 7.1, 7.2, 7.3, 25.1, 25.3, 31.1, 31.2, 31.3, 39.1 thru 39.7, 42.1 and 42.2. I guess I am not sure what I am getting from where really. They are all pretty much Tri Cities though. I guess I am thinking putting on a preamp and see what I have? The channels I do get seem much cleaner than the 20 year old UHF antenna I replaced. The KVEW 42.1, 42.2 actually comes in very good right now.
