I regularly use an active 41" monopole to accurately measure electric
field
strength over the range of 10 kHz to 30 MHz. That's a ratio of 3000:1,
and
that is 25-year old technology.

And your variation of gain, excluding mismatch, is...?

And that should be complex gain, since in the stated application you are
concerned about phase and magnitude.

Also, don't forget about the mutual coupling between elements. What happens
to it over a 3000 to one bandwidth? Remember we are talking about an array
of antennas, not a single isolated one!
