brian,
thanks for the detailed reply. the probe location tweaking idea is good. i plugged the into my calculator, and since the AP is set to Ch11 and my antenna is tuned for CH6, there is a .1" diff in the probe position. wonder how that affects the SWR & gain. would be nice to be able to plot SWR vs channel for a particular design.

i'm using decent quality N jacks w/ gold plating, too, although the bodies are chromed not silver (won't silver corrode outdoors?). i'm hooking it up to 30ft of LMR400 to get it into my bro's house, which makes about 2dB loss not including connectors & pigtail.

i've tried just about every pointing direction i could and so far the best is about 12dB directly connected to the pigtail. i don't have control over the remote AP (no i am not stealing a connection...my bro is a prof @ the college, and they just haven't gotten around to installing AP's on his street yet), so I'm pretty much stuck w/ whatever the antenna setup is (which, by the way is a Yagi pointed away from me).

thanks again for the help. seeing your dish setup also has put some ideas into my mind about how to hang the antenna on the roof w/o drilling into it.
