Optus 3G Antennas: Getting a better signal for your mobile phone and wireless data card.

 

 Mobile Phones and Datacard

Please identify your data card or mobile phone when emailing for advice -they all tend to take different connector leads!

If possible, confirm the model number from a label. We don't currently have pics of all optus phones. Please email us with model number.

Methods of Connecting

	A direct patch lead or an adaptor is the best way of connecting. Usually has a FME male connector on one end , the right hand side in the photo. This has become a de-facto standard for mobile antennas.   Unfortunately there is no standardisation on the other connector used to connect to the phone or data card. There are too many to put on the website at present so you will need to identify your modem model number from the above links and email us the details.
	Some phones don't have a socket for an external antenna so they have to be fixed on to a cradle like this to make a connection. CRADLE ON SHOPPING CART
	Also, some USB modems don't have a socket for an external antenna so they have to be connected via an inductive patch connection. INDUCTIVE PATCH ON SHOPPING CART
	We found that this is also a good way of making an inductive patch coupler. Works well at both 900 MHz and 2100 MHz bands. You'll need THE ANTENNA THIS ADAPTOR TO MAKE IT FME MALE The antenna can be fastened down with velcro or double sided tape.

Antennas for Optus (including Exetel Optus)

 

 

	Optus operate HSPA 3G (YesG) services known as HSPA on both 900MHz and 2100 MHz and it can be difficult to know which bands are available, or give the best service, in your locality. A solution to this problem is to choose an antenna such as this Yagi "triangle antenna" which covers both bands. ANTENNA ON SHOPPING CART This is an indoor panel antenna which fits on a wall (complete with wall mounting bracket) ANTENNA ON SHOPPING CART These antennas do not come with any additional cable so you'll need to order this to your required length separately. POSSIBLE CABLE ON SHOPPING CART         NANOBRACKET ON SHOPPING CART
	Left is the TC483 and probably solves 90% of phone reception problems. Works OK on the 900MHz bands but not recommended for the 2100MHz bands
	These work well on both the 900 and 2100MHz bands. CLIP- ON ANTENNAS FOR LAPTOPS AND VERY THIN MONITORS SHOPPING CART

Other things you might need:

	Hooded Wallplate ITEM ON CART
	Wall bracket to support antennas ITEM ON CART
	Low loss FME male to FME female extension cable ITEMS ON CART
	Its often a good idea to put your USB modem on the end of a USB extension lead to get it into a better spot. ITEMS ON CART
