Yagi Antenna Problems

[Guest]

My outdoor antenna was picking up all local channels (digital and analog) before and after the switch. A very strong windstorm came through recently and we noticed that we only had channels on 2 & 8 left. It turns out that the rest of them are broadcast on UHF so apparently something on that circuit is goofey. Nothing appears to be loose or broken on the antenna or the leads. I am tempted to swap out the 300 to 75 ohm transformer as that is the cheapest thing to start with.
Any ideas would be appreciated---Thanks ahead of time

After a windstorm I would be checking the antenna "aim".
Use tvfool to determine where it should be aimed and then you can verify with a compass or compass app on your smartphone.
