Low Loss High Power Corrugated coaxial cable and connectors

Description

These are professional low-attenuation high power transmission line cables for high performance applications within the telecommunications sector. Radio broadcasting, TV broadcasting, GSM and other sectors.

These cables are ideally suited for the demands of professional radio and TV stations, WLAN, 3M GSM networks, WLAN and extra-long transmission line runs. Available in all major sizes of 1/2 inch, 5/8 inch, 7/8in, 1-1/4in, 1-5/8in and 2-1/4in, ask for a quote, if you need unlisted type. Constructed of a closed-cell polyethylene dielectric and welded-seam solid copper conductors, these cables have passed rigorous testing and meet exacting performance specifications. They are available in standard polyethylene or flame-retardant polyethylene jacket materials, and with premium VSWR levels in several telecommunication bands.

Our opinion: If you plan on using long runs of cable (25 meters and more) or plan on using more than 1KW of power, we strongly suggest that you seriously consider this cable. The savings in greater output power and high power handling justify the extra cost. There is a reason why many professional radio and TV stations use Cellflex cable.
