as for a better antenna for the TH F6A, nearly anything other than the stock 
duck that comes with it.
as for specs, well, it is supposed to offer a 50ohm load on 144-148, 
222-225, and 430-450MHZ.
I doubt there is any gain factor what soever, but the specs likely claim 
unity gain.
The Maldol antennas are supposed to work gang busters with the th F6A and 
any HT really.  I use an MFJ dual band super flex long antenna on mine, and 
it works fine on 220 as well, but I doubt it's tuned for that band very 
well.
One thing with HT antennas, is the bigger and longer they are, the better 
they perform....Unless it's a UHF only HT in which case a 6 inch antenna 
will work the best...other than a properly designed 5/8's wave, but you run 
into ground plain issues with those on HT's.
To get the most out of an HT antenna, it should be one of the longer, near 
quarter wave on VHF style that most of the antenna makers carry.
