So the range is identical to a discone? 50-1300 MHz ? I don't really
understand the band calculations.

The 1:3 SWR bandwidth of the X-5000 is app. 80 to 1300Mhz.

The "bandwidth" is actually 3 band coverage - 144-148 MHz, 440-450 MHz
and 1.2 GHz. An antenna like that is pretty deaf at all other
frequencies - it's a very NARROW-band antenna.

BTW, a discone doesn't really have gain - it's just a very wide band
interface between the cable and space.
