A couple of random thoughts on this thread: Antennas: Very large antennas will mostly be made of metal or metallized mesh, with the holes being somewhat smaller in linear dimension than the smallest wavelength the antenna is intended to work with. That's still likely to be much larger than the wavelength of visible light, and much larger than the typical air molecule. The upshot of this is that visual brightness (on a linear scale, W/m^2 or the like), drag and SRP are likely all to be proportional to the physical area of the threads of the mesh, not the overall dimensions of the antenna. And, therefore, proportional to each other. Solar panels: Just the obvious comment that some observations should be made at small phase angles, where brightening and/or glints might be anticipated from surfaces normal to the incident sunlight. ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www.satellite.eu.org/seesat/seesatindex.html
