I am one of those 88. Well at least one who has modified other peoples 
work on some antennas that have been mapped.
An example ... Way: Murchison Widefield Array (607964749) - there will 
be 2,048 dipole arrays here .. I have chose to map them as an area as 
that is easiest at least for the moment.

I have tagged it as
     "name"="Murchison Widefield Array"
     "description"="2048 dual-polarization dipoles when combined forms a 
single telescope"
     "antenna:configuration"="dipole array"
     "frequency"="80 - 300 MHz"

There are located near a collection of other radio telescopes ... higher 
frequency ones .. with steerable dishes.

The ones I am mapping are certainly conspicuous.

So .. what is the best way to map them?

That is the function of this list, does not matter how many.. just get 
the tagging as good as we can and then let the mappers use or not use it.
