Does a Slim Jim antenna need to be grounded?
The antenna does not need a ground to work, since it is a half-wave design. For lightning safety, the best thing would probably be to mount a lightning arrestor on a metal plate mounted on a ground rod, and run the coax through the arrestor.

What kind of antenna do you need for an apartment?
MFJ makes an apartment antenna which is a base coil and whip with a mounting system. They work about the same as a mobile antenna. They also make a bracket that holds two mobile whips to make a dipole. Wire antennas can be dipoles, loops or endfed antennas. Usually there is insufficient room for half wave dipoles, except for ten meters.
What kind of antenna do I need for 145 MHz?
VHF/UHF (145 MHz and up) antennas are small – if your window points to the right direction, and you live on the 6th floor, a small yagi in front of it can be good for serious DX when the propagation is right. You can also hang a dipole in front of the window, which will be good for local contacts and working the repeaters.
What kind of antenna do you need for a ham radio?
Your neighbors and landlord may not appreciate the beauty of your ham antenna. Full size antennas are surely prohibitive. A multiband antenna is probably the first choice. Of course if you have a single band transceiver, like many QRP radios, then a monoband antenna is good.
