Question Remove (trilens) radar reflector from mast?

Couple years ago I installed a Luneburg radar reflector (specifically, the medium size Trilens) on my mast. Pretty high, maybe 40' up. Based on the specs I expect that it works pretty well though I don't really have any actual confirmation. I sail in the Chessie and I was never caught in fog but I want to be on the safe side.

BUT: This thing is a perfect halyard catcher! Two or three times each year, something gets wrapped around it and, given the height were it's at, it takes me an hour or three of fiddling to sort it all out.

I am considering to take the reflector off the mast and to just hoist it on a flag halyard when I need it.

This will probably make the reflector bounce around a bit more. Will that affect its reflectivity? Given the supposedly rather isotropic radiation characteristics of a Luneburg reflector, theory says it should not.
