Note that attenuation values are given at 400 mhz but can and do often have significantly different values at other frequencies.
Coaxial cable sizes chart.
Coaxial cables are used in high frequency transmission especially for transmitters and receivers computers radio and tv transmissions.
Always check with a coaxial cable vendor for values specific to the type you plan to use.
This multiplier factor is why you should keep cable installation lengths between radios and antennas as short as practical.
Properties of popular coaxial cables.
The most commons sizes of coaxial cable are rg 6 rg 11 and rg 59 some of the size differences are demonstrated in the image below.
This has been tested as a great balance between power handling a low loss.
Coaxial cable has a distinct thick round shape because of its interior insulation layer.
Attenuation db per 100 feet.
From digital television to internet to phone service cable has become a major medium in the multibillion dollar telecommunications industry.
Coaxial cable size identification by jacob workman digital television is one technology that often uses coaxial cable.
Coax losses shown above are for 100 feet lengths.
The varied mechanical thermal and electronic properties of coaxial cables mean that they can be used up into the ghz levels as per cable type.
The following cable guide lists standard flexible low loss semi rigid and conformable micro coaxial and corrugated cable as well as associated product links.
Standard coax impedances are 50 75 ohms.
339 coaxial cables m cw a edition 27 published 01 04 2015.
Loss is a length multiplier so a 200 ft length would have twice the loss shown above and a 50 ft length would have half the loss.
Its size makes it look very different to other types of cable such as twisted pair or ethernet cable.
Coaxial cabling is the means by which millions of people receive various services.
