Better range and signal antenna

After purchasing the Weboost Sleek I wanted and even better signal, so I simply upgraded to the 311703 antenna. Now my signal strength averages four to five bars. Wish I would have bought a Weboost years ago. Best product and customer service!

Bottom Line Yes, I would recommend to a friend

Question: Hello I have a dual band signal booster 1850-1990 mhz and I need to buy the antenna ,wich is the one I have to get ? Thank you

Answer: Thank you for your question! There is a variety of connection ends for the 12 inch antenna. We recommend reaching out to us directly, so we can be sure to suggest the antenna with the correct cable end. Many of our vehicle boosters are now SMA, but were formerly FME.

Question: Hello I wanted to know instead of buying a 900/1800 antenna I could get a smaller one and it would work the same Thank you

Answer: Thank you for your question. This particular antenna is used for European frequencies. You may want to look at this antenna as it will cover frequencies used in the US: The smaller 4" antenna will be better in 4G frequencies, but the 12" antenna will be better in 3G and voice signals. If you have any other questions you can reach out to us here:

Asked by Gugak 4 years ago

Question: The specs says that the antenna works with the frequencies 1710-1880 MHz and 1850-1990 Mhz. So I expected that it would allow phones operating at 1800 and 1900  Mhz obtain better performances using the weBoost Drive 3g-flex. Am I wrong?

Answer: We are able to help with the 1900 band (1850-1900) for many carriers, as that falls within our range. However, we are generally not able to cover bands that offer the 1800 as the range does not match up with ours. We always recommend reaching out to your carrier and determining which bands the carrier uses to operate, as many times carriers outside of the U.S. use higher frequencies to operate voice signals off of. It's important to look at the ranges for your carrier and how they are paired, as they may use a portion of the 1900 for uplink, and a portion of another for downlink as an example. For additional questions, feel free to reach us at our online support center here:

Asked by Gugak 4 years ago

Question: Will it work with the Drive 3G Flex? I live in Brazil and my carrier use the 1800Mhz frequency. However, my cell from work uses a different carrier with 1900Mhz frequency. Is it a dual antenna?

Answer: This antenna will not provide much help on the 1800 band. However, if you are looking for an antenna to pair with the Drive 3G Flex for your 1900 MHz phone, then you will actually want the following:

Asked by lester 4 years ago

Question: is this a good substitute for the 311125?

Answer: This antenna is more commonly used for international frequencies, therefore, it would not be a good replacement for the 311125. The 311125 is recommended in most cases, if you are looking for more voice coverage with many vehicle boosters. Pairing this antenna optimally, will largely depend on what you are pairing it with. We would be happy to look into your situation, to help make the best antenna recommendation. You can submit a help ticket here:

Asked by Muddog 5 years ago

Question: Will this work with 3G/4G?  Would this be an upgrade to the antenna that comes with the WeBoost 4G-S? 

Answer: No, this antenna will not work with the Drive 4G-S. This antenna is for the 900/1800 international frequencies. I believe you were looking for the 311125. However, the magnet mount antenna that the kit came with is actually stronger for the 4G data frequencies. If data is your priority, you will want to stick with the one that it came with. If your main priority is voice, then yes, the 311125 is the upgraded magnet mount antenna.
