10 Best External Cellphone Antenna of December 2025

• WHAT IS IT?: The strongest outdoor antenna for cell phone signal booster kits, featuring a parabolic grid with gains of up to +26 dB. This cell phone booster antenna has an ultra long range (10 miles) with high gain and directionality on all frequencies between 600 MHz and 6500MHz. This cell phone antenna has been optimized for lower or upper portions of the ultra-wide bandwidth. All cellular bands: LTE, GSM, ISM, CDMA, UMTS, 2G/3G/4G/5G; WiFi and all carriers: T-Mobile, Verizon, and AT&T.
• BENEFIT: This outdoor ultra-wideband antenna is 6 times more powerful than other antennas that come with any cell phone booster kit. By putting more directional gain on your antenna, you’re able to increase your signal quality, reach farther to the cell tower, and dramatically increase your booster’s performance. The radiation cone (between 4 to 20 degrees) of this directional cell phone antenna allows a narrow, fine-tuned, and farther aim than most wideband antennas
• WHO IS THIS FOR?: For those needing a Weatherproof long-range outdoor antenna. If you live in a very rural area with spotty to no cell signal, this wideband cellular antenna allows you to find towers up to 10 miles away compared to the 2 to 5 mile reach of an omnidirectional or yagi antenna. This cell phone antenna booster is ideal for weak cell phone signal areas who have trouble even reaching their nearest cell tower. For those who want to increase the output of an existing booster system.
• THINGS TO CONSIDER: This external directional antenna 4G LTE requires a signal booster amplifier. The cell phone antenna extender works with all cell phone signal boosters brands: weBoost, SureCall, Cel-Fi, etc., WiFi boosters, and hotspot boosters (Pepwave, MoFi, Netgear Nighthawk, etc). Assembly is required. Tools Required: 10mm wrench, socket, or nut driver, or alternatively an adjustable wrench or pliers to set up. Mount and cables NOT included. Outdoor cell phone antenna
• REQUIRES A SIGNAL BOSTER: This long-range cellular antenna is an aftermarket product that upgrades most signal booster KITs and is very directional, so in order to increase the reach and gain of the antenna, its beam has been narrowed to around 7 degrees (the typical yagi has a radiation pattern of around 45 degrees). This cellular antenna range booster is like a laser pointer that maintains the strength of its beam from a great distance but needs to be aimed much more carefully.
