The main thing is if there was a broadband antenna for the frequency
of interest, the losses in the cable, even a few feet could kill a
signal above 1G .

but isn't that why we have active antennas? to overcome the losses?
also your comments contradict these antennas:

and they're supplied with cables that go up to 8 meters.
