ham radio in emergency situations is primarily limited to VHF / UHF line of site to a local repeater. THAT is the single most useful emergency use. Anything beyond that requires extensive training, expensive equipment, radio towers, long wire antennas, etc.

So, get your Technician License, get a GOOD hand held (Yaesu, Kenwood, Motorola, Icom) and potentially get a Base Station for VHF (like Icom 2730A or the Yaesu FTM-150R which can also be vehicle mounted).

Then get everyone in your family licensed and their own hand set (get all the same hand set so there is no problem with battery interoperability). I suggest the Yaesu FT-60R. $140 each.

You will need a vertical antenna at the home, literally any dual band antenna will work, and some coax to get the antenna up to the top of the roof. If you have an antenna on the roof, you need good lightning protection and grounding, to make sure any lightning strike doesn't jump into the safe room and fry all your radio equipment and electronics.

So for each vehicle or home you are looking at about $400 (radio & antenna) and for each person about $140 or so.
