The Best Cable for LTE Antenna Applications | Low-Loss RF Cable Guide - Eteily Technologies

By


In current wireless communication systems, antenna performance is determined by more than just the antenna design; the RF connectors (coaxial cable) that connects the LTE antenna to the modem or router is also crucial. Using the optimum cable for LTE antenna applications results in less signal loss, consistent connectivity, and increased data throughput.

Eteily Technologies India Pvt. Ltd., a leading manufacturer of RF antennas, SMA connectors, and cable assemblies, assists telecom integrators and OEMs in selecting the appropriate coaxial cable for best LTE and 4G performance.

In this comprehensive guide, we cover LTE cable kinds, specifications, major features, and how to select the best one for your needs.

Why Does Cable Selection Matter in LTE Antenna Systems?

LTE runs in many frequency bands (700 MHz to 2600 MHz and beyond). As frequency increases, so does signal attenuation in cables. Poor quality or inappropriate cable selection might lead to:

  • High signal loss.
  • Reduced LTE speed
  • Weak signal reception.
  • Increased VSWR
  • Network Instability

The appropriate coaxial cable reduces attenuation and maximizes signal efficiency.

Common Cable Types for LTE Antenna Applications.

The following are the most commonly utilized RF coaxial cables in LTE systems:

1. RG 174 Cable

Ideal for short-distance, small LTE devices.

Features:

  • thin and flexible.
  • Lightweight
  • Easy routing in tiny enclosures.

Limitations:

  • Higher signal loss.
  • Suitable for short lengths (usually less than 1 meter).

Typical use:

  • IoT LTE modules
  • embedded LTE routers
  • Compact tracking devices.

2. RG 58 Cable

Best for medium-range LTE setups.

Features:

  • 50-ohm impedance.
  • Moderate flexibility.
  • Better shielding than RG174.

Advantages:

  • Lower loss compared to RG174.
  • Cost-effective solution.

Applications:

  • Industrial LTE Routers
  • Outdoor LTE antennas
  • Automotive LTE systems

3. LMR Series Cable (Low-Loss): ✔ LMR-100

  • Similar size to RG174
  • Lower attenuation.

✔ LMR-200

  • Medium thickness.
  • Good balance between flexibility and little loss.

✔ LMR-240
  • Perfect for medium-length outdoor LTE setups.
✔ LMR-400

  • Very little signal loss.
  • Ideal for long-distance antenna installations.
  • Ideal for: High-performance LTE base stations, industrial systems, and lengthy outdoor cable lengths.

4. Semi-rigid, low-loss custom cable assemblies.

Eteily Technologies manufactures customized LTE cable assemblies with:

  • SMA connectors
  • RP-SMA Connectors
  • N-Type Connectors

These are intended for telecom OEMs that require precision and durability.

Key Features of the Best LTE Antenna Cable:

When selecting the ideal cable for LTE antenna applications, consider the following characteristics:

1. Low attenuation (signal loss).

Lower dB loss per meter results in a stronger LTE signal.

Example (about 2.4GHz):

  • RG174: High loss.
  • RG58: Moderate Loss
  • LMR-400: extremely low loss.

2. 50 Ohm Impedance.

LTE systems usually require a 50-ohm impedance to provide appropriate matching and low reflection.

3. High shielding effectiveness

Good shielding prevents electromagnetic interference (EMI) and signal leakage.

Search for:

  • Braided shielding.
  • Foil and braid combo

4. Outdoor durability

When installing external LTE antennas, verify that:

  • UV-resistant jacket.
  • Weatherproof insulation.
  • Temperature resistance (-40°C to +85°C or more)

5. Flexible or Semi-rigid Structure

Choose flexibility dependent on the application.

  • Flexible: For embedded systems.
  • Semi-rigid: For stable industrial configurations.

Technical Specifications to Check

Parameter Recommended Value
Impedance 50 Ohm
Frequency Range 700 MHz – 2600 MHz (LTE bands)
Attenuation As low as possible (dB/m)
Connector Type SMA / N-Type / TNC / MMCX
Operating Temperature -40°C to +85°C
Jacket Material PVC / PE / LSZH
Shielding ≥ 90%

How to Select the Best Cable for an LTE Antenna

Step 1: Determine the Cable Length.

Longer wires cause more signal loss. Always utilize the shortest possible cable.

Step 2: Check the LTE band frequency.

Higher frequencies necessitate low-loss cable types.

Step 3: Consider the Installation Environment.

  • Indoor: Standard PVC cable.
  • Outdoor: UV-resistant PE cable.
  • Industrial: Heavy-duty jacket.

Step 4: Match connector types.

Check compatibility with LTE router or modem connectors.

LTE Cable Applications

The best LTE antenna cables are commonly used in:

  • 4G LTE routers.
  • Industrial IoT gateways
  • Vehicle Tracking Systems
  • Smart Meters
  • Security surveillance systems
  • Telecom base stations
  • Remote monitoring solutions.
