Yea don't be fooled by the big 20k watt antennas. If you got a small radio thats only pushing 3w deadkey with a 20w peak, that antenna aint gonna do **** but look good. The key, as stated above, is get an antenna that matches the radio
So if you got a stock cobra 29 that wont get out with a firestik, its damn sure not gonna work any better with a coiled antenna. If your running a connex like blkdodge04, then yea a coil is your best bet
I say, for starters, get a cobra 29 with a firestik. Then once you learn a little more you can upgrade. And make sure you have a good ground. "toolbox grounds" usually don't cut it
