Answer
Hi Steve,
A signal amplifier will likely improve the reception but it may or may not completely solve the problem. I think it is the best place to start. Other options that may also help is to move the antenna outside and or get a larger more powerful TV antenna such as the HD Stacker antenna >. You may find that moving the antenna to a different location within the attic will help. The cause of the problem is likely a tree or trees swaying in the wind and by moving the antenna to another location may avoid the signal obstacle that is causing the problem and improve reception.
If the signals are very weak to start with the wind itself could cause the interruptions in signal but is likely trees causing the problem.
A very good preamplifier choice for your set up is the LNA 200 preamplifier >
