That tree has been trimmed back, so I'm estimating 15-20 ft clearance. It actually needs to come down, but I fear the estimate of how much it will cost.
That switch box looks ideal. I'll need to add two in-line coax surge protectors to the two video feeds in the basement.
I wonder if I'll need a new ground rod outside the house, or if I can ground to the water in at the same location in the basement. I'm sure the installer will work it out.
Thanks again for the input.
One more question, in measuring the distance between antennas on a vertical mast, you are measuring distance between elements rather than mounting points.
Also, looking for info on max antenna height based on antenna weight, and stacking order—I imagine FM followed by 7694 and then the 1080, although I can see having the 1080 in the middle (both are high V though).
And while I'm at it, maybe the biggest question is how my tuner will handle the change from one antenna to another. It would be dreadful to have to rescan the channels every time I flip the A/B.
One more: Using this formula,

Calculate the minimum vertical spacing you need between the antennas. To do this, divide 467 by the lowest channel frequency that you are receiving. The low frequency for Channel 2 is 54-55 megahertz so the best minimum space is 467/54 = 8/64 feet.

It would indicate a minimum 2.7 ft space between the two antennas, and a 15 ft space between the FM antenna and the others, which would indicate a separate mounting. Is that right?
