For the sake of my continuing education what would I need in terms of
minimum equipment to make a meaningful comparison between antennas? Just
to keep it simple I'm working on two meters and seventy five centimeters
so far in my EMCOM prep work.

That's a tall order. What characteristics of the antennas are meaningful
to you? Gain in some particular direction and elevation angle, minimum
gain at any azimuth at some elevation angle, pattern circularity,
mechanical ruggedness, corrosion resistance, portability, size, weight,
SWR at some specific frequency or over some particular band, efficiency?
Does it have to have some characteristic(s) when mounted on some
particular vehicle? Some point on some vehicle? Some class of vehicles?

What sort of accuracy would make the results meaningful?
