Just asking :-) The 4G USB modem I use connected to my home router has ports for antennas, in use with some stubby ones for a slight improvement in reliability (but I still get signal outages since 3G was turned off). You need two antennas for 4G since there are two radios used with polarised transmition (so rotate the antennas 90 degrees apart). Some modems might even use four antennas. I read 5G can use up to 64 antennas or more, so I've got no idea how the (MIMO) antennas for that work, it's getting into "magic" territory. For my own use I don't care, the 4G speed is way in excess of what I need. I want 3G back so it works all the time in the first place. > Time ago, there were designs for building your own directional antena > for WiFi. Maybe there are now for cellular routers. Surely many people > are in that situation. Even by building a parabolic with the router inside. I'm in the process of setting up a DIY parabolic antenna outside for 4G now. Most designs online are for 3G, but can be adapted. The modem won't be inside the parabola, but close by to keep the coax length short. Then I'll try making an extra-long USB extension cable running back to the router indoors. Weatherproofing and mounting it high enough are the tricky parts. -- __ __ #_ < |\| |< _#
