michael,

Your proposed mounting sounds like it should be okay. You might pick up a length of 1 1/2" EMT from your local home center and save on shipping cost. I'd be inclined to use two of those Ronard adapters spaced at least 24-36" apart since the 7698 is a very large antenna and will be subject to very substantial wind loading. Hopefully, that existing rigid pipe is securely mounted. You sure don't want the whole rig to come down in a storm!

Keeping the OTA antenna as far away as feasible from the dish should be a goal. The presence of the antenna won't affect the dish's reception, but the presence of the dish too close to the OTA antenna will affect it, probably in the form of distorted reception patterns and altered front/back or front/rear ratios. It shouldn't have much, if any, effect on the forward reception so it may not matter a great deal.
