Yes. An antenna with the wrong frequency range, poor efficiency, damaged cable or unsuitable pattern can produce more loss than the router’s original antenna. A long, thin coaxial cable can consume the gain advertised on the antenna, especially at higher frequencies. A highly directional antenna aimed at the wrong tower can also make the connection less stable, and a high-gain antenna may have a narrow vertical pattern that misses a nearby elevated or low…
Cellular Antennas and MIMO · 2026-06-14 When should a site use an omnidirectional antenna instead of a directional antenna?Use an omnidirectional antenna when signals may arrive from different directions, the equipment moves, there are several usable towers, or simple installation is more important than maximum gain in one direction. It is common for vehicles, vessels and sites with reasonable general coverage. A directional antenna is useful at a fixed fringe-coverage site where testing identifies a suitable tower and interference can be reduced by focusing the antenna. It r…
Cellular Antennas and MIMO · 2026-06-13 Why do many 4G and 5G routers require two or four cellular antenna connections?Modern 4G and 5G systems use MIMO—multiple input, multiple output—to send and receive through more than one radio path. Two antennas are common for 2x2 MIMO, while higher-performance 5G routers may use four for 4x4 MIMO. The separate paths improve capacity and reliability when the network and radio environment support them. Leaving ports disconnected, combining them incorrectly or placing all antennas in an unsuitable arrangement can reduce performance. U…
