What kind of antenna connectors (3) are in the following picture? That is a picture found on the Decrypted Tech website of the electronics in a TRENDnet TEW-684UB. It is a USB to WiFi network adapter. When assembled this model doesn't have external antennas. Would connecting antennas to the 3 nubs extend the adapter's range? This is a dual band WiFi adapter, 2.4 and 5 GHz, so I should get antennas that work with both bands. I plan to drill holes in the case of the adapter for mounting the external part of the antennas. What kind of antennas do you recommend? I was thinking of buying something like this [link to product sold at Amazon]. That's the 3 Dbi kit but there's a 5 Dbi kit, too. However, I don't know if those antennas have the right kind of connectors and the kit contains only 2 antennas so I'll need to find a third. One could argue that I shouldn't get this WiFi adapter and just buy something more expensive with antennas due to the cost and sacrifice of warranty by upgrading the TEW-684UB myself. However, regardless of that I'm tempted to try this for fun.
