So first of all, thanks everyone for the help already provided.

I've been running the Wineguard 7694 for almost a year and for the most part it's great. However, occasionally (especially mornings) I can't get several of the major channels that I normally can get. The antenna is mounted on a pole approximately 6 ft above my roofline or 30' or so in the air.

My question is what can I do to eliminate these deadtimes? I've considered the following options, but don't know which to start with or how to decide:
Increase height of mount
Install pre-amp
change antennae

Thanks in advance for any advice or suggestions.
