Par EndFedz EF-SWL

The Par EndFedz ® EF-SWL is an end-fed short wave antenna optimally designed for 0-30 MHz reception.  The radiator is 45 feet of #18 black polyethylene coated Flex-Weave wire.

The radiator wire is custom made for us.  It is a stranded #18 copperweld with a slippery polyethylene jacket.  Breaking strength is 280 pounds. Very flexible yet small diameter. The black polyethylene jacket is also very abrasion resistant. The UV resistant matchbox houses a wideband 9:1 transformer wound on a binocular core.  Unlike other transformers, external stainless studs on the matchbox allow the user to configure the primary and secondary grounds for best noise reduction at their particular location.

Radiator length: 45’ of #18 black polyethylene coated Flex-Weave wire
