There is little reason to put the antenna or mini on a tower. The e-field antenna--maybe. I have not used my e-field components so have no experience. There may be issues with long cable runs.
Yes, any E-field antenna should be higher. Over your roofline. I had one about 20 feet high, which is what was recommended here.
I don't know —and I don't think anyone does— how an E-field antenna would perform at greater heights.
There will indeed be issues with long coax runs, namely, voltage drop! RG-6 cable has a thin layer of copper over a steel core. The DC resistance would be so high at 185' that the amplifier would not work. Perhaps if you used RG-11. I have some similar F-11 with an aluminum shield; the center conductor being copper over an aluminum core. But it's been a long time since I looked up the ohms per foot and calculated the I²R losses.
Another thing to consider is if the metal tower would affect it. It could couple to it.
I say, forget the tower. Put all your lightning antennas at a distance from it. Later, you can elevate the E-field antenna and see how it works.
