What is the best way to send an HD signal from a camcorder to a television that's FAR away?

My church wants to set up a camera on our pastor and just feed the live HD signal to a TV in the back of the church (approx 150ft). what is the best/cheapest way to do this without purchasing a 200ft. HDMI cable? is there a wireless method?? I’ve seem this done before so i know it’s possible. we are trying to avoid keeping the camera in the back and zooming in 100ft (degrading HD quality). thanks!!
