I have to wireless antennas like this:

and two wl500g connected trough a sma cable to each of them.

everything is fine for a few days but sometimes, randomlly, the whireless link drops. it lasts for a few minutes (more or less) and after that it's up again.

what could be the cause of this? are the anntenas causing this ? or the routers ?
