for best rsults you'd need 2 of them, if you have 2 antenna router, to make it worst...to be functional those need to be connected with very short cables, literally directly to the ports, witch makes router box very much not ergonomical..
for stronger signal better use some other solutions....routers are not made for those antennas, but yep you can squeeze some range out of it....you can try with single yagi as well it wont hurt...i did some modifications for a hotel wi-fi in the past and was not that bad, but i used old tp-link with single antenna router...what is more important is clients cappbility as thay may not comminicate very well in longer range...but give a try and see for yourself, my experience says you can get a booster for the same price and effort... _________________ Atheros

Does anyone know the ohms of the antennas?

I assume you bought it somewhere? If the antenna was designed for WLAN, most likely it would be 50 Ohm, or if for TV, most likely 75 Ohm. But to be sure, look for the datasheet.
And going into Alozaros' comment, be wary on not losing on a long/poor cable the gain of the antenna. If you go that way, as suggested you can mount that router in a waterproof box, or use a premium coax, or you could ponder an USB cantenna because the USB cable can be longer without so much sacrifice.

Or do I need to have the unused port with the stock antenna?

Not good idea to leave a radio port with a impedance mismatch (50 Ohm <-> infinite). Reflections, noise, eventually damage risk. It's better to have an antenna there.
On dd-wrt there is/was also the antenna chains settings, in which you could tweak what do you want to do with each radio. And you need to ponder (or trial and error) on how much EIRP you're gonna put through each one without injecting too much noise and/or how much sensitivity you can achieve with such settings. Also, you didn't state what kind of diversity your hardware has, so YMMV.
Bottomline: I played with these ideas in the past, power is not everything, but in some cases a Yagi or a cantenna may help. _________________ If you want support, please read first the announcements and forum rules.
