Will the classic inverted V work on 2.4ghz (802.11b/g WiFi)?

I just installed a mini PCI WiFi card in my T23 laptop and routed
the two coax cables from the card to the back of the LCD
screen. I needed two temporary antennas and it dawned on me
that maybe a pair of inverted V antennas might just work, at
least on a temporary basis until I get a high gain sector antenna
built or even a Bi-Quad setup.

I made each leg on the two antennas 30.5mm long. The coax
runs straight down from the feed points about 4" then snakes
it's way back inside the laptop. The whole shebang is just taped
to the back of the laptop.

Will this work? Any problems? What about gain?
