I've had some wire antennas up in the air for over 20 yrs. Used rosin-core
solder. Surface looks weathered but below the surface the solder is stable,
connection good. Location is high acid, salt, blown sand/dust, relatively
high pollution. YMMV
I use silver solder on pressurized copper tubing HVAC connections but don't
waste it on antennas and the melt temperature is higher risking compromise
of the small wires. Never saw the need to use silver solder for antennas so
I guess preferred is in the eye of the beholder, as in hold still so I can
get a good solder joint!
