I just picked up 200 ft of rg8 at radio shack for 40 bucks. 10 bucks for
50 foot run. Anyways, there was a website I came across recently that
showed the swr rating of different size rg cables based on band. I
searched for rg8 and the site popped up. It was complete with charts, etc.
Very nice. It only takes a few minutes to find if you don't mind trudging
through the sites.

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.

It was a close out special at $10 per 50 feet. I had to hit two stores
before I found any, a Ham who was working at the first RS store had bought
out all that his store had in stock. I bought a 100 feet at that price at
the second store. I also have a 50 foot section of some of their RG-8 stuff
I bought 20 years ago for SSB CB use (yes, I once was wooed by the dark
side). Can't tell any real difference on HF frequencies when using the old
RS RG-8 or some new RG-213 I got from Texas Towers.

Loss is right. Sorry about that. RS is trying to get rid of everything
radio. These were on clearance. Normally sold for much more.

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.
