Signal Improvement Solutions (Cellular)
Cradlepoint ARC CBA550 LTE Adapter includes 2 antenna ports to attach external cellular antennas. See below for different options for high gain and high performance indoor and outdoor antennas to improve the signal strength and indoor coverage. Additionally, see below for RF bidirectional amplifiers/ distributed antenna systems/ repeaters/ small cells to further improve indoor coverage without directly attaching pigtail/ cable the device.

Cellular Repeaters/ Bi-Directional Amplifiers

Because the Cradlepoint ARC CBA550 LTE Adapter device has an external antenna port you could use the high gain external antenna kits above to boost your signal. However, if your outdoor signal is very weak, or you require a very long cable run to get from the outdoor antenna to the device (long runs lead to large signal loss) consider using an RF bidirectional amplifier/ repeater suitable for the supported bands and cellular operator to boost your indoor coverage:

Customize your solution

STEP 1: Determine what frequency bands your operator uses here, then click on the frequency band link to view the best ranked cellular antennas compatible with the frequency band that both your device and your cellular operator supports. Your Cradlepoint ARC CBA550 LTE Adapter operates on these frequency bands: LTE Band 2, LTE Band 4, LTE Band 5, LTE Band 12, LTE Band 13, LTE Band 14, LTE Band 66, LTE Band 71.


STEP 2: Determine the cable length you need from the outdoor antenna to the Cradlepoint ARC CBA550 LTE Adapter and configure your length here (select N-Male on both ends)


STEP 3: Determine if you need a lightning protection device. If you do, you will need a jumper cable.


STEP 4: Order the pigtail for your modem below:


STEP 5: If the pigtail's Connector 2 is FME-F you will need an N-Female/FME-F adapter to mate to the N-Male cable in step 2. Alternatively, select an N-Male/FME-M cable in step 2 above (more expensive and less re-usable) to avoid requiring this adapter.
