Homer,

How are you matching it? I had a 2 element quad for 11m for a year or so matched with a 1/4 wave of RG-59. VSWR was under 1.5:1 for the whole band. I wouldn't expect to see a significant difference in the VSWR, but it won't cost anything to raise it and see.

I once built a 2 element Delta Loop for 10m and fed it direct with RG-11, figuring the feedpoint impedance should give a decent match to 75 ohms. I was wrong. There was no analyzer or noise bridge to be had so I don't know what the impedance actually was, but I ended up throwing together a wire gamma match that matched it perfectly.

I don't recall the exact dimensions of the 11m quad, but the DE was just the standard 1005/f(MHz) and the reflector was 5% longer. Spacing was right at 5 feet. That was a great little antenna, fed in the corner of the diamond for vertical polarization.

Is that another clothesline?

Man, how do you have time for all this neat stuff? I'm doing good to keep my grass cut!
