If there are a lot of trees between your antenna and the location of the broadcast towers, and if it is breezy, the signal can become erratic. I have had this problem at our last house where the leaves  moving would upset the signal. During the wintertime with the leaves off the trees there is less of an effect from the wind and barren trees.  I only include this as information as additional things that can upset receiving signal.

Also depending where you are, there can be tropospheric effects on the quality of the signal you are receiving. An excellent resource for seeing the 
Current effects from tropospheric disturbances is here:

When you see the conditions for today, there is a ‘monster’ in the Gulf of Mexico and off of the southeast coast of the US that rears its ugly head as the weather changes!

From what you have described, it doesn’t sound like you have a problem with your ability to receive a good signal, just having problems with the signal getting to your antenna .  How far are the broadcast antenna from your location?  

If you want a good resource for signal pickup, I would suggest the following site:


There is a lot of information as well as several knowledgable people on the forums.
