AD Tech, you are right on the money... I just took the preamp out of the signal path, so it's jsut the antenna right into the tablo, and it works great on all channels. And when connected directly to my TV, the stations that were at 50-70% are now all at 100%. It's a clear day now, so I'll measure again when we have a storm.
Thanks!

In case this may help someone later, AD Tech was right not only on all counts, but especially on the point about adding up your losses. That gave me the spefici info I needed... I calculated my losses using this calculator... http://otadtv.com/cables/index.html Remember to calculate your connectors (at .5 db per connector). In my case I had a total of 9.6 db loss. My antenna has 10-12db gain according to the specs. And that worked, although as AD Tech said, I should add a preamp of about 5-8db. I don't have one of that rating right now, so I'll see how it goes, and add one if I need it.
