Cell Phone External Antenna Type Descriptions

External antenna adapters connect to cell phones in a variety a ways. Here are some examples.

Newer Phones

Most of today's cell phones, iPhones, smart phones, etc. do not have usable RF ports that enable you to connect an external antenna to. In these cases, we recommend cellular signal boosters that don't require a direct connection to your device. See:

• Mobile Signal Boosters
• Building Signal Boosters

Back Plug

Plugs into the adapter port on the upper back portion of your phone. A rubber or plastic plug may need to be removed. Press firmly to ensure a good connection - do not twist. WARNING: Using too much force could damage your phone.

Ring

Slide onto the base of your cellular phone's built in antenna. Press down firmly to ensure a good connection. Be sure to lower your phone's built in antenna. This type of adapter is available for only a few phone models.

RF Charger

RF Chargers are antenna adapters that have a built in battery charger. A single plug into the bottom of your phone will allow you to charge your phone while using your external antenna. Without the RF Charger you would have to unplug your charger to use your antenna.

Sleeve

Top Plug

Plugs into the adapter port on the top of your phone. A rubber plug may need to be removed. Press firmly to ensure a good connection - do not twist. Using too much force could damage your phone. A small number of top plug phones require the removal of the original antenna to expose the port.
