Being that you are going to use a transceiver instead of a scanner, it is a good idea to have a good impedance match just in case you accidentally key down, so a simple ground plane with 50ohm cable like RG58 or RG8x will work fine. Your connector on the radio is a BNC, on the antenna it may be an "N" type (if commercial grade) or a PL-259 if a cheapie or scanner antenna. If you don't have the skill set for dressing cable and soldering connectors, I would recommend a kit from a higher grade supplier that includes the antenna, pre-terminated cable of the length you need with the proper connectors and antenna mounting hardware. The problem with most cheap scanner antennas is that they usually are multi-band or, if mono-band ground planes are not long enough for the air band, being sold primarily for the VHF high band of 148-174. Ground planes cut for air band can be expensive due to more limited, usually professional suppliers, so the most reasonable option is often to buy a ground plane for VHF low band (30-50) and cut the radiator and radials down, the benefit being the elements are often thicker (giving you greater bandwidth with a good match) and the mount more sturdy.
For a simple "check book" solution I would go to this site:http://www.wingsandwheels.com/antenna_vhf_airband_gps_mobile_e.htm
Call those folks up. All the antennas are air band, the Larsen they have looks pretty good for what you are needing, and they sell cable and connectors, probably could fix you up with a prepared cable as well.
Alternatively you can make your own stuff that would perform just as well for a fraction of the cost (like a couple copper welding rods and a PL-259 bulkhead connector), but without proper knowledge and test equipment your results may vary. But making and experimenting with antennas can be a great deal of fun, I have probably made hundreds of antennas and RF distribution systems over the years for all sorts of applications from HF to microwave, and once you start it can become addictive. One way or the other I would not recommend using any antenna or feed system that is not reasonably well tuned because unlike most others here you have a transmitter to protect, though most portables have circuitry that protects against broken or missing "rubber duckie" antennas. Even my VHF feeds, two of which use a real Narco NavCom with no chance of accidentally being keyed, have custom, perfectly tuned, pattern tailored antennas.
