Just a last question: I have a passive cooling server I am using as my wireless access point + 3g modem. The device has two antennas and right now I am connected each antenna to the "main" connector of each 3g modem and wireless card. Everything is working fine What about with a 4g modem? I guess it needs two antennas? </blockquote> Yes, they will use the antennas for TX and RX diversity and you'll get slightly better signal levels with multiple antennas. Also, for LTE you'll need multiple antennas to reach the higher bandwidths that LTE provides. <blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;"> What if I am putting in parallel wireless and 4g cards on the same two antennas? </blockquote> I wouldn't recommend this. You should have at least one antenna for each card, and ideally as many antennas per card as the card wants. For most devices that means 2 antennas; you can skip the GPS antenna if you want.
