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.  Examples are given in the manual.  Output is via a silver/Teflon® SO239 UHF connector (ready to accept a PL-259).  Lead-in coax cable is not provided.

The radiator also attaches via a stainless stud allowing it to be removed, or replaced with a different length radiator for experimental purposes. The included manual shows typical radiation patterns for selected frequencies through out the HF spectrum. (This is a receive-only antenna).
