I think this additional request may have gotten buried in the Stacker "discussion"; I appreciate everyone's effort to be helpful and will write it off to some people liking chocolate ice cream and others liking rocky road.
If anyone has the desire to provide some additional help, I'll try again:
I plan on mounting the OTA antenna to a roof-mounted 2" rigid conduit (outside diameter 2 3/8"), which also will hold a DirecTV dish. Here's a picture of the pole:
Rigid conduit mounting pole
Since the pole is so big and the mast clamp on the antenna only goes up to 2" OD, I think I need something like these for mounting:
Ronard 8200 vent pipe clamp
Galvanized 1 5/8" pipe
Is this the way to go, or is there a better way to mount the HD7698P?
The satellite dish points to 136°, the antenna will point to 81°. I will have only two to three feet of separation, but since they are so directional and offset by 55°, I'm hoping that I won't have any interference between the dish and the antenna. Does this look OK, or do you think I'll need more separation?
