When deploying mobile network equipment—whether it's a 4G LTE booster, a 5G router, a cellular base station, or a Distributed Antenna System (DAS)—choosing the right coaxial cable is critical for performance.
Mobile networks operate at high frequencies (700 MHz to 6 GHz) where signal loss is significant. The wrong cable can turn a strong signal into a weak one, reducing data speeds and call quality.
This comprehensive guide explains which coaxial cables work best for mobile networks, from small home boosters to large-scale carrier installations.
Mobile network signals are high-frequency RF signals that are extremely susceptible to cable loss. Here's why cable selection is critical:
Mobile networks operate across multiple frequency bands:
| Technology | Frequency Range | Signal Loss Challenge |
|---|---|---|
| 4G LTE | 700–2600 MHz | Moderate to High |
| 5G Sub-6 | 3.5–6 GHz | High |
| 5G mmWave | 24–39 GHz | Extreme (requires specialized cables) |
All mobile network equipment uses 50Ω impedance. This includes:
Using a 75Ω cable (like RG-6) will cause impedance mismatch, signal reflections, and poor performance. Always use 50Ω cables for mobile network applications.[citation:2][citation:5][citation:8]
For home cellular boosters, 5G routers, and small office installations, these cables offer the right balance of performance and cost.
Impedance: 75Ω
⚠️ NOT RECOMMENDED: While some consumer boosters come with RG-6, it's 75Ω and not ideal for mobile. Use 50Ω cables instead.[citation:3]
Impedance: 50Ω
Attenuation: Ultra low-loss
Best For: Home boosters, 5G routers, short to medium runs (under 50 ft)
Key Feature: UV and weather resistant for outdoor use. Excellent for 4G LTE and 5G Sub-6 signals.[citation:6]
Impedance: 50Ω

Best For: Very short runs (under 10 ft), test equipment, temporary setups
Key Feature: Low cost, flexible, readily available. Not recommended for permanent installations due to higher loss at mobile frequencies.[citation:10]
| Cable | Impedance | Best Run Length | Best For |
|---|---|---|---|
| Wilson400 / LMR-400 | 50Ω | Up to 50 ft | Home boosters, routers |
| LMR-240 / HF240 | 50Ω | Up to 20 ft | Indoor, tight spaces |

| Cable | Impedance | Loss @ 900 MHz | Loss @ 2.4 GHz | Best Use |
|---|---|---|---|---|
| RG-58 | 50Ω | 32 dB/100m | 55 dB/100m | Short cables, budget |
| LMR-240 | 50Ω | ~17 dB/100m | ~28 dB/100m | Indoor, short runs |
| LMR-400 | 50Ω | ~10 dB/100m | ~17 dB/100m | Professional, medium runs |
| LMR-600 | 50Ω | ~6 dB/100m | ~10 dB/100m | Tower feeds, long runs |
| HELIAX 7/8" | 50Ω | ~4 dB/100m | ~6.5 dB/100m | Carrier, base stations |
Mobile network equipment uses specific connector types. Match your cable to your equipment:
| Connector | Impedance | Common Use |
|---|---|---|
| N-Type | 50Ω | Base stations, antennas, professional equipment |
| SMA | 50Ω | Routers, modems, 5G devices, small antennas |
| F-Type | 75Ω | ⚠️ Consumer boosters (not ideal for mobile) |
| BNC (50Ω) | 50Ω | Test equipment, some radios |
Cable length directly impacts signal strength. Use these guidelines:
| Cable | Max Length (4G LTE) | Max Length (5G Sub-6) | Application |
|---|---|---|---|
| RG-58 | 10-15 ft | 5-10 ft | Test equipment, temporary |
| LMR-240 | 20-30 ft | 15-20 ft | Indoor, short runs |
| LMR-400 | 50-100 ft | 30-60 ft | Professional, moderate runs |
| LMR-600 | 100-200 ft | 60-120 ft | Tower feeds, long runs |
| HELIAX 7/8" | 200-500 ft | 150-300 ft | Carrier infrastructure |
Note: These are guidelines. Actual distance depends on signal strength, equipment, and acceptable signal loss.
Every foot of cable adds signal loss. Use the shortest possible cable run. For example, one user found that a 35 ft run of coax was causing issues with 5G n71 band (2.5 GHz) performance.[citation:11]
Match connectors to equipment. For 5G routers, SMA is common. For professional equipment, N-Type is standard.[citation:10]
Outdoor cables should have UV-resistant PE jackets. Use weatherproof tape on connections exposed to the elements.[citation:1][citation:4]
Excessive bending can damage cables. Respect minimum bend radii. LMR-600 has a bend radius of about 4 inches, while HELIAX 7/8" requires 5 inches static bend radius.[citation:8]
Use a cable tester or signal meter to verify proper performance after installation.
No. RG-6 is 75Ω and will cause impedance mismatch. Always use 50Ω cables like LMR-400 for 5G applications.
For home boosters, use Wilson400 (LMR-400 equivalent) or LMR-240 for shorter runs. Both are 50Ω and designed for RF applications.[citation:6]
Yes. LMR-400 is excellent for 5G Sub-6 frequencies (up to 6 GHz). It offers ultra-low loss and high flexibility.[citation:4]
Use LMR-400 for runs up to 50 ft, or LMR-240 for runs under 20 ft. Match connectors to your router's antenna port (usually SMA or N-Type).[citation:10]
Yes, LMR-400 cables can be terminated with SMA connectors, N-Type, or other 50Ω connector types depending on your equipment.[citation:10]
LMR-600 has lower attenuation (signal loss) than LMR-400. It's used for longer runs or more demanding applications. Both are 50Ω and operate up to 6 GHz.[citation:4]
For 5G Sub-6 (3.5 GHz), LMR-400 can run 30-60 feet with acceptable loss. For longer runs, upgrade to LMR-600 or use a signal amplifier.
HELIAX is carrier-grade cable used in base stations, DAS, and cellular towers. It provides extremely low loss and excellent shielding for professional installations.[citation:8]
5G mmWave (24-39 GHz) typically requires specialized waveguides or high-frequency cables. Standard LMR cables may not perform well at these frequencies.
No. TV coax is 75Ω (RG-6) and will not work properly with 50Ω mobile network equipment. You need a 50Ω cable like LMR-400.
We stock professional 50Ω coaxial cables for all mobile applications—from LMR-240 for indoor setups to LMR-600 for tower feeds and HELIAX for carrier installations.
