Can I use only one antenna port on a two-antenna access point

I have a 2,5 km WIFI bridge, that has stopped working after 6 years. It was run by Gateway GN-AP01G (802.11g) with one antenna output and a yagi antenna connected to it. The same setup on the other side of the bridge.
I need to buy a similar setup fast, and D-Link DAP-1360 may do the work. But it has TWO antenna connectors. What will happen if I only use one of them? Is it going to be ok, if I choose to do use only 802.11g (not 802.11n) ? Is one of the connectors "main" and the other one "aux" , or is it sending the same thing on both when in G-mode?

Thank you for your comment. I ordered two DAP-1360 so will test this on Wednesday when it arrives.  I had the old APs (one-antenna APs called "Gateway") in a weatherproof box connected to the Yagi antenna via RP-SMA to N-connector, so I'm planning to use the same antenna again. It has the same connection as the old "Gateway".
Thanks for the burn out-tip. I hope it is ok for the electronics that I have the 18dBi yagi on one connector, and a regular 2dBi dipole on the other?

The different antennas should be fine. I've run many APs with a 2 completely different antennas connected and they're all still working. They should both 'appear' to be the same load to the transmitter.

If those D-Links don't work, I would suggest something intended for that purpose... like the Engenius ENH200EXT (Amazon) (~$78 USD each w/free shipping). Alternate source - ENH200EXT on Newegg (~$80 USD each).

http://www.engeniustech.com/business-networking/outdoor-access-points-client-bridges/16125-enh200ext is the support page, though I think that model has actually been discontinued.

Thanks. I'll have a look. Actually I wanted to buy a pair of Ubiquiti Powerstation 2, similar to that EnGenius model, but unfortunately they don't have proper PoE, and I need to run a switch in the same box on the same DC. Bad thing that the D-links use 5Volt. I hope my PoE splitter (switchable 12/5volt D-link) can give enough current to it and also to the 5 volt switch that I'll put in the same box.

If the AP gives the option to turn off antenna diversity you can use one antenna.
