are all the active aviation gps antennas (trimble, king, garmin, lowrance,
etc) interchangeable?

which specificiation do i need to look at to evaluate the equivalence?

======================
Only if you believe all men are created equal!

The difference is whether they are active or passive.
Passive does not offer any GAIN.
Active offers a built in amplifier which offers some gain. NO additional wiring is required if you get an Active antenna.
On LONG runs of antenna coax you may want a bit of a foot-up with an antenna with gain. What is a long run? I don't know. My Passive antenna came with about 10 feet of coax and works well.
