I went looking for photos of W5LFL operating in orbit that included a view of the antenna in the window, but I couldn't find any. I did find NASA Photo S83-36894: which is described as "Astronaut Owen Garriott in Ham Radio simulation in One-G trainer in bldg 9A" and I think there's a pretty good chance that the white thing in the lower-right ...

Of course, the answer to this question is certainly "it depends." Yes, different antenna elements in close proximity can interact and cause interference problems. The most notable issue would be a degradation of both antennas. You don't want that. But you might not have a problem - again depending on what sort of antenna you wanted to put up, and ...

Just using it as a support will definitely have some kind of interaction with your antenna, unpredictable but empirically measurable. BTW, my first thought is that you can try to take advantage of that TV antenna as a capacitive load at the end of your EFHW (make sure to disconnect the TV antenna from any feed line of its own though). Using it like this will ...

Spacing of parallel dipoles influences the bandwidth you can achieve on every particular band. The smaller the spacing, the more narrowband antenna becomes. However, there is a trick you can use to achieve a little larger bandwidth while not spacing the dipoles too much. See my website here.
