This unique product connects an external antenna to a variety of USB Modems. If you have a modem that does not have a plug or jack for an external antenna, this universal adapter will work. The cable ends in a SMA (f) connector (Remember to buy an antenna with this adapter).
REMEMBER - You need to buy an external antenna to use with this adapter. This adapter does not work on its own. Have a look at the antennas on the left as options. If you do not have an antenna your best option is to buy the kit shown on the left: The high gain antenna kit for data and voice reception 7 m cable with 3G generic adapter cable includes the antenna, 7m cable and adapter.

Why should I use a Poynting antenna with my Poynting adapter:
It is extremely important to consider that you are buying the best coupler in the world which links the modem/phone at all frequencies. If you combine this to an antenna with frequency limitations then the following may happen:
-May work fine today (because the base station is talking to you at 900 MHz) but tomorrow it may assign a 1800 frequency because the network is more congested and you will get erratic performance.
-Even if a frequency limited antenna works fine and consistent at the moment it will fail the moment the network gets upgraded and start using some other frequency bands.
Just to elaborate:
a) Tranditional GSM voice uses from 890-960 MHz. Many yagi antennas you buy for “900 MHz” does not cover all the frequencies in this range. While you speak on a cell phone the device “hops” from frequency to frequency in this band at 200 times per second (this is the buzz you hear on the radio when a cellphone operates close to it). If the antenna is not well designed it will work erratically with this “hopping”
b) When the spectrum got congested cellphone companies started getting spectrum in 1850MHz-1990MHz or 1720MHz-1880MHz bands. Here the phones also “hop between frequencies” but more so, some base stations will pass you from the 900 MHz band to the 1800 band and back. If your antenna cannot do this when this happens then suddenly you will have very bad results and may think the coupler has broken.
c) When 3G arrives the frequency band shifts to 1990MHz-2150MHz. If your antenna cannot do this you will not get good 3G. This could mean you still sit with slow data while much faster is available.
