For safety's sake, I installed an 8 foot grounding rod which I tied to the common ground via the water piping. Just before entering the house, I installed a lightning arrestor, which I attached to the grounding rod.

I finished assembling the GH10 today. I am still considering how to best mount it permanently, but for now I have it hanging from the eavestrough at the front of our house. To minimize sway, I hung a hanging basket with a couple bricks in it from the bottom. Reception is great with all major Buffalo networks coming in at 100%.

I purchased some 1/2" CPVC tubing to build the frame today. CPVC is much more rigid (and expensive) than standard PVC/PEX. Even at 1/2", the frame is very sturdy - I placed a board on top of the raised section and stood on it. Drilling the holes for the colinear rods was probably the biggest challenge. I think I did a fairly decent job of keeping them on a flat plane, but it was tough - even with the drill guide (below), particularly the 4 holes that had to go through the PVC Ts. A drill press probably would have made the job easier. Applying PVC cement to the joints and connecting all of them at perfect right angles took some care as well. This project is definitely a more complicated build than the standard SBGH described on the digitalhome.ca forums, which uses steel fencing as the reflector.

I found a short piece of 3/4" PVC in the basement, so I decided to test the "Versatile Drill Guide" (below). This simple tool made it quite easy to drill perfect 90 degree holes through the center of the tubing. I anticipate this will really come in handy when mounting the 20 colinear reflector rods. As you can see in the video below, the result is a tight fit, where some force is required to position the rods, which will make the milimeter tolerances of the rod separations easier to attain.
