Do you have an URL for a floating reflector biquad?

Here's one; hope it is clickable as the URL is split weirdly as I construct
the message:

I pieced together the URL. Pretty funny seeing the dish on the car
roof.

I can't really tell if the ground wire connects to the reflector or
not. Since they didn't use PCB but rather copper sheeting, it is clear
they didn't make a connection from the back.

I saw Jeff's reply and if floating is good enough with him, I would
float it only because soldering to a ground plane is work. Generally
you want to tin the area where the connector will be soldered, then try
to solder the connector without melting the inside. I would much rather
just epoxy the connector to the reflector, which means the only wire
you have to solder is the one that brings ground to the biquad element.

You will undoubtably ruin one or two until you get the hang of
soldering to them, so have a few on hand. If you don't ruin one, then
build another antenna! If you have a ham flea market in your area,
these connectors are a quarter. Buy a handfull.
