Introduction

This installation guide will help you connect your LTE 4G External modem antenna (ST2018) equipped with an I-PEX MHF1 connector. Following these step-by-step instructions will ensure a proper and secure connection, enabling optimal performance for your LTE 4G External modem antenna.

 

In the box:

  • 1 pcs External 4G Modem Antenna
  • 1 pcs I-PEX MHF1 adapter
  • 1 pcs Mounting bracket

 

Step 1. Choose a Suitable Location

 

NOTE: Alway measure your signal reception of chosen location prior to installation

 

  • Locate a spot for your antenna that offers an unobstructed view of the nearest cell tower or base station, or an open area. It's best if this location is elevated and doesn't have any obstructions like buildings or trees. 

            You can also install the antenna on the exterior of the building.

 

  • Fasten the Mounting bracket at you chosen spot using the 4 holes in the bottom part of the bracket. 

 

NOTE: However, it's important to ensure that the antenna is securely mounted and doesn't pose any safety risks to people or property.

 

Step 2: Mount the Antenna

  • Once you have securely fastened the antenna bracket to the wall, proceed to attach the External 4G Modem Antenna by removing the fastening nut situated at the bottom of the antenna head and also peeling off the adhesive cover.

 

  • Insert the antenna from the top into the bracket and ensure that the adhesive sticks to the bracket.

 

  • Next, use the fastening nut to tightly secure the antenna head to the bracket, clamping the antenna and bracket together.

 

  • Note the antenna should only be mounted on a wall. Not in a overhang or ceiling. 

 

NOTE: Verify that the antenna is firmly in place and won't slip or dislodge.

 

Step 3: Connect the External 4G Modem Antenna to the LTE door central

NOTE: Connecting the antenna may vary depending on the unit, such as whether it's a ST2029 or a ST2043 door central. This installation guide is specifically for the LTE door central (200-002) used with the ST2020 intercom. If you are uncertain about the type of unit you have, we recommend contacting Steplock Access to confirm prior to proceeding with the installation.

 

  • Remove power from the LTE unit completely. 

The modem is located in the following place:

 

 

 

There are two antennas attached to the modem. 

  • 4G_M = 4G Main antenna
  • 4G_A = 4G Assist antenna

 

 

  • Only remove the antenna labeled 4G_M (Main). 

 

CAUTION: When removing the I-PEX MHF1 connector from the modem board, exercise caution. It is recommended to use rubber coated pliers and gently pull the connector head upwards.

Avoid pulling the cable from the side, this can cause damage to the connector. 

Do not pull too hard, as this can damage the connector or the cable/antenna. 

If the connector is difficult to remove, do not force it. Instead, use a gentle rocking motion to loosen the connector from the socket. You may also need to wiggle the connector back and forth while pulling it gently upward to remove it.

Additionally, be careful not to apply excessive force on the connector with the pliers when removing it. It should come off smoothly and easily. 

 

  • Thread the I-PEX MHF1 adapter through the existing cable holes at the bottom of the LTE chassis to install it inside the LTE door central.

 

CAUTION: Ensure that the converter connector for the I-PEX MHF1 adapter does not make contact with any of the circuitry inside the door central. 

 

  • To connect the I-PEX MHF1 adapter to the modem at the 4G_M (Main) antenna location, you should use a set of rubber-coated pliers. Carefully position the I-PEX MHF1 connector directly on top of the 4G_M connector on the modem, and press down gently. Avoid pressing the connector in a sideways manner to prevent damage. 

 

  • Connect the antenna to the  I-PEX MHF1 adapter and tighten the nut. 

CAUTION: Ensure that the converter connector for the I-PEX MHF1 adapter does not make contact with any of the circuitry inside the door central. 

 

  • Power the unit.
