The Share-It router has 2 kinds of antennas in it boss:
1st is the internal 3G/3.5G/GSM antenna. This is the antenna that sends and receives the 3G/3.5G/GSM traffic from the cell site to the Share-It device. This is the same internal antenna that you have in your cell phone. If you're already getting very good signal strength in your area, or "5 of 5 bars", then you don't need an external antenna. All cell phones nowadays don't really need to have an external antenna anymore. The last cell phone that I own that had an external antenna that really protruded from the unit was the Nokia 5110.
2nd is the WiFi antenna. This has no effect on the 3G/3.5G/GSM signal strength but is just used for the WiFi traffic, or the traffic between the Share-It device to your laptop. The Share-It device, a Huawei B9333 Wireless Gateway, has an external WiFi antenna port.
So to answer your question boss - pwede nimo tauran ug antenna ang antenna port sa imong Share-It router, BUT, it won't increase the speed between the Share-It device to the cell site. It will only increase your WiFi coverage.
In my case, nag-taud ko ug WiFi antenna kay kung dili ko magtaud, maglisod ug pickup sa WiFi signal ang akong laptop kung mu adto ko sa pikas kwarto. Pero kung naay WiFi antenna, maski 3 houses away gikan sa among balay, maabut sa akong signal sa WiFi.
Here are actual pictures of my Huawei B9333 unit

To the Smart apologist above who thought that I was an idiot like herself who just didn't know what kind of signal I was getting,
*NOTE* that the indicator LED's in my Share-It router all indicate that I was getting 3.5G coverage, or HSPA / HSDPA, and my signal strength is also the strongest possible signal because I am located very near the cell site.
Yet I am still getting speeds at around 100kbps only, sometimes even as low as 30kbps.
