Thanks.

The reflector looks a bit on the short side, resonant around 26.53, whereas 5% lower would be around 25.895 (assuming a 27.185 fc). Other than that, it all looks right. According to the numbers I crunched the feedpoint impedence should be around 100 ohms at that spacing with a reflector cut for 25.895. And your 1/4 wave section was about 7 1/2 feet? Hmmmm..

Thanks for the reference on the 1/12, I'll dig more into that when I'm not supposed to be working (!).

Your reflector is only 2 1/2% longer than the DE, do you think that's enough?
