Our 4G vehicle booster kits include a mini (4-inch) magnet-mount antenna. Other vehicle antennas may not provide enough adequate gain (signal boost) for your 4G LTE data. However, we've recently released two new 4G mobile antennas – the 4G-OTR Trucker Mirror-Mount Antenna (SKU #: 304414) and the 4G-OTR Antenna Truck Edition Spring-Mount (SKU #: 304415). These antennas can be used as a better option in some mounting scenarios and are available by searching the SKU numbers listed.
In some cases, 3G antennas will effectively boost signal better than the mini magnet antenna that's provided. Consequently, 4G will not pass through the antenna since it's only usable for 3G signals. We recommend only using 3G antennas for 3G mobile boosters and not for 4G.
