Struggling with slow Wi-Fi or patchy mobile broadband? You’re not alone—especially if you live in a rural area or a home with thick walls. The solution? A high-quality external aerial can dramatically improve your signal strength, speed, and reliability.
But with so many options (omni-directional, directional, MIMO), how do you pick the right one? As UK signal specialists, we’ve tested dozens of aerials—here’s our expert guide to choosing the best for your needs.
Why Add an Aerial to Your Router?
Most routers come with weak internal aerials that struggle in low-signal areas. An external aerial can:
✔ Boost 4G/5G and Wi-Fi reception (critical for rural users).
✔ Extend coverage (helping eliminate dead zones).
✔ Stabilise connections (no more dropped Zoom calls!).
✔ Improve download speeds (especially with MIMO aerials).
Real-world example: One of our customers in Cheshire saw their 4G speeds jump from 5Mbps to 35Mbps after installing a directional aerial.
Types of Aerials for Routers
Omni-Directional Aerials
These pick-up signals from all directions, making them ideal if you’re unsure where the nearest mast is.
✅ Best for:
- Urban areas with multiple masts
- Moderate signal improvement
- Users who can’t mount an aerial in a fixed direction.
🔹 Our top pick: 4G LTE Omni-Directional Aerial – A sturdy, weatherproof option perfect for UK conditions.
Directional Aerials
These focus on one strong signal source (great if you know where your nearest mast is).
✅ Best for:
- Rural locations with weak signals
- Long-range connections (if you have line-of-sight to a mast)
- Maximum speed improvement
🔹 Our top pick: SignalBooster Pro Directional Aerial – Used by farmers and remote businesses to triple their speeds.
MIMO Aerials
Essential for 4G+/5G routers, MIMO (Multiple Input, Multiple Output) aerials use multiple data streams for faster, more stable connections.
✅ Best for:
- High-speed broadband users
- Streaming, gaming, or large downloads
- Futureproofing for 5G
🔹 Our top pick: 5G MIMO Panel Aerial – Lab-tested to deliver 2x faster speeds than single aerials.
Key Factors Before Buying
✅ Compatibility
- Check if your router has SMA or TS9 ports (most 4G/5G routers do).
- Ensure the aerial supports UK frequencies (e.g., 800MHz for rural 4G, 3500MHz for 5G).
✅ Signal Strength & Mast Location
- Use Ofcom’s mast map to find your nearest transmitter.
- In cities, an omni-directional aerial usually works best.
- In the countryside, a directional aerial pointed at a mast is far more effective.
✅ Indoor vs. Outdoor Use
- Outdoor aerials perform best (mounting on a chimney or pole avoids wall interference).
- If indoor-only, place near a window facing the mast.
✅ Weather Resistance
UK weather is harsh—look for IP65 or IP67-rated aerials to withstand rain and wind.
How to Install Your Aerial
1️⃣ Find your router’s connectors (usually SMA or TS9).
2️⃣ Mount the aerial (outdoor placement works best—even a garden pole helps).
3️⃣ Use high-quality, low-loss cable (cheap cables can weaken the signal).
4️⃣ Test with a signal app (like Network Signal Info on Android).
Pro tip: Slightly adjusting a directional aerial’s angle can double your signal strength!
