The antennas for which I've seen anecdotal data
have a great deal in common and are probably interchangeable
among some brands. Having said that, I'm unaware of any
"standard" that the industry has embraced in order to
achieve a broad range of plug-n-play compatibility
across product lines for active antennas.
ARINC ( http://www.arinc.com/ ) was set up about 40 years
ago as a sort of "club" of suppliers. One of many common
interface standards agreed upon by the club was the "2 out
of 5" switching protocols for allowing a Narco LOC receiver
to frequency switch an ARC glideslope receiver.
Until and if someone like ARINC offers an active GPS
antenna standard (and manufacturers embrace it) then
you're pretty much on your own to try it. If your
GPS receiver offers a satellite signal strength display,
then you're in a position to do A vs. B comparisons
of two antennas and can tell US what your findings are.
So the sort answer is, "Haven't the foggiest. Phone
calls to the suppliers of equipment under consideration
may be helpful.

Hi Bob and all,
|
I'm very satisfied with a Laipac Technology active antenna and a Garmin
Series 400 GPS. Flawless reception, even inside a closed hangar.
Some info at http://contrails.free.fr/gps_en.php
FWIW,

One point to consider...
With "active" GPS antennas, Garmin and Bendix/King require different "boost"
levels.
Comant offers separate antenna models to accommodate these differences.
Don't know for sure, but it would seem reasonable that an antenna with less
than the required boost would give poor performance...

A good resource....

An active antenna primarily overcomes coax losses....how long
do you need your cable to be?
The other option is an in-line amplifier, then use any antenna
you wish (without over amplifying the signal)....
