That's true, but increasing Tx power may or may may not work, even in the
case of an omni, it depends on the conditions at the remote stations as
well. For an omni setup, I'd go for the card with the best receive
sensitivity (Cisco?) as a starting point. If it's got higher power, that's
then a bonus, or you could add a small (bidirectional) amp.
A small masthead bidirectional amplifier can sometimes help, though often
you can get the same results with a GOOD AP masthead mounted (PoE anyone?)
