Anyway, someone mentioned to me years ago that it is a bad idea to mount

Assuming for the moment that the above is true, then same logic leads me

is

bad, then mounting things on a canopy attached glare screen is also bad.

This finally leads me to how to mount FLARM antennas. Often FLARM

are mounted onto the glare screen. But two FLARM antenna coaxes would

option=

screen. However this might impact coverage.

What are your wise opinions?

One answer would be to use a SMB Connector, which is a snap-in co-ax
connector, just requires a firm pull to disconnect (adrenalin helps!).
