If you live in hilly terrain like the Dandenong Ranges or the Yarra Valley, you know the frustration of dropped calls and unsent texts. Standard cellular signals rely on line-of-sight propagation, meaning rising hills and tall forests easily block wireless frequencies.
The Primary Causes of Signal Shadow Zones
In locations like Berwick, reception dropouts are usually caused by three key geographical factors:
- Ridge Shadowing: Rising hills block incoming tower lines, trapping homes in valley shadow zones.
- Canopy Absorption: Tall mountain ash and pine tree leaves hold moisture, which absorbs and weakens high-frequency 4G/5G signals.
- Building Insulation: Modern foil-wrapped insulation and steel roofs block whatever weak signals remain from entering your home.
The Solution: High-Gain External Antennas & Amplifiers
The most effective way to solve indoor blackspots is by installing an ACMA-approved Cel-Fi GO repeater. By placing a directional Yagi antenna high on your roof clearing local lines, we lock onto distant cell towers, route the signal inside, and amplify it to 5 bars throughout your home.
