(When did FreeBSD-net become about antenna theory?) The answer (of course) is, “it depends”. Mostly on “what bands” though your antenna and cables will have some effect as well. Some WiFi cards these days employ a form of beamforming or even MIMO. Older cards could use selection diversity to enhance reception. Some cards are, as you say, architected to have a 2.4ghz chain on one antenna and a 5ghz chain on another. So we’d have to know more about your wifi card as well.

We move around and sometimes use Ethernet, sometimes PPP directly on DSL and sometimes we connect to a local wifi hotspot. To get the best connection I have mounted an external, multi-band antenna on the trailer and connect it to one of the antenna connections on the wifi card. > > My question is, can I split the antenna connection and use both antenna connectors on the wifi card (or three if I have that kind of card) or will that mess up the connection. I know that each connection is for a different band. Different camp grounds use different bands and sometimes I need to switch the antenna to get a better Internet connection. It would be nice if I could just have both of then connected to the external antenna. > > Cheers. > > -- > D'Arcy J.M.
