Hi Joe, and welcome...

Does cable length have a factor in this?
Yes, you will definitely lose DB the longer your coax (cable) run is. Approximately how many ft do you have from the TV to antenna, and are there any splices or splitters between the run?

I was thinking about adding or replacing the UHF section of my antenna with a Channel Master multidirectional UHF antenna hoping that I could get a better signal.
The multidirectional will be a huge help for UHF, but one of the bigger factors that might be causing bad reception, is the deflection caused by locating the antenna in your attic. The radioshack antenna that you have is also optimized for the VHF frequency? I wonder if you're actually not receiving some of the VHF channels as well?

Just bought a new SONY LCD tv with a built in ATSC tuner and noticed that it intermittantly drops the signal.
We've seen some reviews at the forum (See: http://www.dtvusaforum.com/dtv-recep...n-ability.html) about some of the digital tuners within converter boxes not performing well with DTV Reception as opposed to competing converter boxes located within the same house - location. The same holds true with DTVs and HDTVs, and I've witnessed this myself with my Mitsubishi 40" LCD HDTV versus my DTVPal Plus converter box. The DTVPal seems to receive all channels in my area with the same type of antenna, as opposed to my Mitsubishi TV which requires movement of the antenna at times to get rid of pixelation. I can't imagine that your Sony TV would have an inferior DTV tuner, but, if I get some time this evening, I'll look around the net. What model number is it?
