Here is
your FMFool...
I put the height at 20 ft.
You have really strong signals. An amplifier is likely to make things worse as it overloads on multiple strong FM signals.
Try it without one first.
If you want an amplifier you can get the CM 7777, which is highly regarded, and has an integrated FM Trap.
The Winegard 269 has better overload resistance....however it doesnt have an FM Trap. So you would need to add in a seperate FM Trap....and they are getting hard to find. The best one isnt waterproof, so you would need a waterproof housing mast mount box for it. The CM 7777 is simpler.
But try it without the amp first. If it works good for you. Then you can get a Winegard CA 8800 FM Band Seperator and have a fantastic FM antenna too!
