SureCall 50ohm Lightning Surge Protector

In Stock

Item Number: 3634
Quantity:

Price:

$58.00

Helps protect an amplifier or modem from power surges such as those caused by a lightning strike to an outside antenna. The protector is inserted inline between the outside antenna and the amplifier or adapter cable, and it must be adequately grounded by running a ground wire into the ground or concrete.

The protector does not connect directly to the amplifier or antenna. You will need a 2' jumper cable to connect the surge protector to your equipment, and depending on your setup, you may also need additional connectors. Refer to the sample setups below for more details:

If you are using an amplifier, the surge protector can be installed at the "top" of the setup (outside, between the antenna and the coax cable) or at the "bottom" (between the coax cable and the amplifier):

  • Option A (surge protector installed outside near the antenna): antenna -> 2' cable -> surge protector -> cable -> amplifier
  • Option B (surge protector installed inside near the amplifier): antenna -> cable -> surge protector -> 2' cable -> amplifier

If you are NOT using an amplifier (i.e. you're connecting your antenna directly to your modem via an adapter cable), you can still use the surge protector. Your setup will depend on whether you're using an antenna with a cable pre-attached to it or not:

  • For antennas with pre-attached cable ending in FME/Female, you'll need a 971113 N/Male to FME/Male adapter, the 952302 2' cable, and the 971107 N/Female to FME/Female adapter: antenna -> 971113 adapter -> surge protector -> 2' cable -> 971107 adapter -> adapter cable -> modem
  • For antennas without pre-attached cable, the surge protector can be installed at the "top" of the setup (outside, between the antenna and the coax cable) or at the "bottom" (between the coax cable and the adapter cable):
    • Option A (surge protector installed outside near the antenna): antenna -> adapter if necessary -> 2' cable -> surge protector -> cable -> adapter cable
    • Option B (surge protector installed inside near the adapter cable): antenna -> cable -> adapter if necessary -> surge protector -> 2'  cable -> adapter cable -> modem

We carry two options for the 2' jumper cable:

  • 952302 2' cable
    • N/Male connectors on both sides
    • Choose this cable if the antenna or amplifier you are connecting to the surge protector to has an N/Female connector. Most users will use this cable.
  • 955802 2' cable
    • N/Male connector on one side and SMA/Male on the other
    • Choose this cable if the antenna or amplifier you are connecting to the surge protector has an SMA/Female connector.

NOTE: This is a lightning protector for 50ohm antennas/amplifiers. If you are using a 75ohm system like the SignalBoost DT or SignalBoost DB Pro amplifier kits, you need to purchase the 859992 75ohm Lightning Protector instead.



  • N-Female connectors
  • Weather-proof
  • Attenuation <0.2 dB
  • Frequency range up to 3 GHz
  • Replaceable gas discharge element (manufacturer will replace as needed)
  • Impedance: 50ohm

The lighting protector must be grounded - to do this, you'll loosen the small screw on the suppressor and insert a grounding wire and run it into the ground or concrete (instructions are included).
