Living in a rural area of Sri Lanka, my Dialog Home Broadband 4G router was stuck with weak signal: RSRP -105 dBm, RSSI -74 dBm, SINR 17, and speeds often 0 Mbps.
Solution: Converted the router (V3E model) into an outdoor unit with two high-gain external MIMO antennas + repurposed an old Dialog Satellite TV dish as a parabolic reflector for one antenna.
Results after the setup
- RSRP improved from -105 dBm → -90 to -95 dBm
- SINR stable 17–22
- Real-world speeds now consistently 15–30 Mbps down (previously <5 Mbps)
How I did it
- Bought two 4G MIMO panel antennas (35 dBi) with SMA connectors
- Mounted the router outdoors in a waterproof box
- Connected both antennas via low-loss coax cables
- Used the original LNB arm of the old Dialog satellite dish and placed one antenna exactly at the focal point – instant parabolic reflector!
Total cost: ~LKR 18,000 (antennas + cables + mounting). No need for expensive Poynting antennas or a new dish.
This simple hack turned an almost unusable 4G connection into reliable broadband. If you’re in a weak-signal area in Sri Lanka, dust off your old Dialog satellite dish — it works perfectly as a 4G reflector!
