UNLESS you happen to be building a high power, multi-transmitter station 
for contesting  The ultimate shielding of coax is limited by the 
RESISTANCE of the shield,and the uniformity of the shield, at the 
frequency of interest. Large diameter coax with a robust copper braid 
provides lower resistance, so if you're fighting for extra dB of 
crosstalk between bands and antennas, bigger coax can help.
