12dBi gain for GSM bands and 11 dBi gain on 3G bands for a total of approximately 5 dBi taking into consideration the induction of the adaptor and cable. Ideal for places where it might be difficult to receive a signal from a 3G transmitter such as summer cottages, caravans, boats, etc. Comes with a clamp for masts up to 50 mm in diameter. and 7 m of low-loss cable with SMA connector and a patented inductive signal coupler (adpt 026) that slides over the 3G USB modem. The wireless signal coupler catches the antenna signal and transmits it to the 3G modem.
Additional information from the manufacturer:Using a 3G USB modem without an aerial socket? Until now there has been no way of improving the reception of these modules. Poynting offers an aerial kit specially designed for new USB 3G units which as also compatible with Huawei E169G, Option iCon 225, iCon 431, iCon 505, and Sierra Wireless Compass-series.
The antenna kit consists of a high-gain multi-ban directional antenna with a 7 m coaxial cable (SMA connector) and a patented inductive signal coupler that slides over the 3G USB modem.The wireless signal coupler catches the antenna signal and transmits it to the 3G modem.The antenna comes with a mast bracket. Perfect for attaching to TV aerial masts. NOTE! The antenna must be mounted vertically as shown above. The antenna is approx. 1 m long.
Positioning the antenna on the ridge of a roof will result in a much stronger signal than a lower position.The antenna can also be used without the inductive coupler and connected directly to a 3G router (e.g. Ericsson W25, Sierra Wireless Airlink, Sarian, MultiTech) or to a 3G PC-Card/ExpressCard/USB-modems with an SMA-converter option.
Keep the cable as short as possible. It can be extended using coaxial cable fitted with SMA connectors.
Important information for installing directional antennas:Your 3G USB adaptor takes up to 1 minute to indicate changes in signal strength. It is therefore important that you take your time when aligning it. Turn it 10 degrees, wait a minute and check the signal strength, turn another 10 degrees, etc.
