Not to muddy the waters, but you can use another TX to resend the signal on one of the other universes, if you need to more distance. I did this in our subdivision to strengthen the signal for houses that were included in the display.
IE Dongle--- > Wireless TX (Uni 1) <<>>> RX (Uni 1) Hardwired to LE (DMX IN) --->> Cat 5 out of DMX OUT 2 to Wireless TX (Uni 2) and so on
