I don't know what kind of cable Radio Shack is selling for that price, but
it must be very poor quality. Probably 5 times the loss of any quality rg-8
size cable at 2 meters and above. RG-8 size cable of any type should be
atleast $ .50 per foot and more like $ .75 per foot or more.

There should not be any tables for SWR for differant cables based on the
band.
Maybe you mean the loss in dB instead of SWR.



One of the basic components of coax cable is the design of the outer shield. The
measure of that shield is optical coverage. Cable is available with optical
coverage that ranges from 80% to 95%.

The optical coverage contributes to the shielding effectiveness and losses
through the cable shield, leakage inductance.

A quick test of shield design is the remove about 1 inch of jacket and inspect
the shield . A tightly woven shield with a lay angle of close to 45 degrees will
have excellent optical coverage.

In the past, RS cable had optical coverage in the 75 to 80 percent range.
