Thanks for the pictures. Nice job on the transformer too! I have watched all of Steve Ellington's presentations on EFHW antennas. He did a presentation where he covered earlier 'wire type' antennas that I found very informative as a new comer.
If I put my transformer up my tower, do you think I should put a choke on the line? I'm wondering if the coax would radiate or influence the resonance? Of course, this is where all the fun comes - experimenting. I like the way Ellington diagrammed his six configurations and took RF measurements at various parts of the coax and wire for comparison.

Thanks for the tips Tom. Yes I have been thinking of grounding and my plan was to put three ground rods in the soil and attach them to the tower legs with #2 copper. I have a question:
Is is possible to connect my #2 ground wire to the ground rod below the surface of the lawn so I can cover the connection up? I didn't know if I could use an anti corrosion compound on the connection then hide it under the dirt. My concern was having objects sticking out of the grass. If it is OK to do this, then I would add additional ground rods 6' away from the tower and connect them as well, below the surface.

They say not to embed a ground directly in the concrete, but you can put the #6 in a conduit and bring that up through the pad... Greq VE3RQY can give you all the details about grounding... keep the top of the pad slightly above ground so no grass clippings etc will lay on it, round the corners if you can
