I don't recommend a solid reflector like you're talking about. Screen type works best just go to the hardware store and get some garden fence. The screen will allow air to flow through and won't give you as much wind load. There's no advantage to using a solid aluminum foil type reflector.Hi ExDilbert,
I've already made the reflector (aluminum foil over thin board) so I think I'll install that and see if that makes any difference first. I seem to get the best reception (20-24 channels) when it's pointed at downtown Toronto. How big a rotation (degrees wise) does it commonly take to make a difference?
