Until around mid 2022 some modem/router devices were blocking external antennas from boosting the 5G signal bands. The antenna ports on these devices were allowing 3G and 4G external signal but not 5G. This has now changed so users can boost their 5G signal via an external antenna which is essential if operating in a low signal area. Results will vary depending upon many factors such as antenna type, location, topography just to name a few. Mimo antennas are recommended. Comnet can provide advise on the best 5G antenna for your application. Contact us by email at email@example.com or call 02 9899 5700 during office hours.
