\"\"<\/a><\/p>\n

My good friend David Cripe (NMOS)<\/a> has recently informed me about a new product he’s offering to the radio community via his eBay store<\/a>: Kev-Flex Stealth Kevlar Antenna Wire<\/strong><\/a>. Kev-Flex looks like a superb option for field antennas of all stripes especially since it has an incredibly high tensile strength. It’s available in 75′ bundles, but Dave can also cut custom lengths. NM0S is also a trusted retailer in the ham radio world, so you can purchase with confidence.<\/p>\n

Here’s the product description and link<\/a>:<\/p>\n

Kev-Flex is a unique antenna wire manufactured exclusively for NM0S Electronics. The lightweight center core of the wire is made from Kevlar fiber, giving the wire its incredible strength. The Kevlar core is wrapped with six tinned strands of 30 AWG copper. The effective surface of the wire creates an effective skin area capable of handling well over 100W.<\/strong><\/p>\n

\"\"<\/a><\/p>\n

The cable is protected from the elements by a coating of UV-resistant black polyethylene. With a total diameter of only 1\/16″ (incl. insulation) and a weight of just 16 feet per ounce, the tensile strength 125 lbs allows lengthy unsupported horizontal runs. Kev-Flex is ideal for extremely long LW-antennas and Beverages and is great for balloon or kite-supported antennas. Its low weight and high break-load makes it most suitable for SOTA activations and other field operations.<\/p>\n

The outer insulation makes the wire kink-resistant, and its slippery finish makes it ideal for stealth antennas that must be passed through trees or other obstacles without snagging.<\/p>\n

This antenna wire is sold in 75 foot long bundles, which is enough for a 40M dipole or EFHW. Two 75 foot bundles would make a great 80M dipole. Custom lengths are available on request.<\/p>\n

Specification<\/strong><\/p>\n
