Absolutely! And this is true of ALL coax types. There's a lot of junk

W4KBX hasn't commented about the frequency at which he intends
to use 100 feet of RG-8X. 0.24 inch diameter coax -- no matter
what type or manufacturer -- isn't the best choice for 100 foot cable
lengths at 21 MHz or above.
It s a much better investment to step up to the next larger diameter
I found that not all RG-8X is created equal. For one project, I
measured 3 or 4 different brands of new RG-8X to find that the loss can
vary considerably. The measurement method was to use 50 ft, snake it
back an forth across the floor so as not to have adjacent coupling, the
ends fitted with

Hi Richard,
Please provide a little more information so that your question can
be answered more accurately.
At what frequencies will you be using your coax?
Will your coax be buried or laid on the ground, or will it not be
in contact with the ground at all?
Many coaxial cables have

RG-8X Belden 100 ft @ 50 MHz has 2.5 dB loss
LMR-240 Times Microwave 100 ft @ 50 MHz has 1.7 dB loss
RG -213 Belden 8267 has 1.5 dB loss at 50 MHz
RG-8 Belden 9913 has 0.88 dB loss for 100 ft at 50 MHz. {Due to the

Richard..If you are set on using the small size the real LMR-240 is the best
bet..also may want to check with MFJ.. they now carry a very good line of
coax!!
