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.

Specifications:

Transformer: 9:1 ratio
Grounding: User configurable
Radiator length: 45’ of #18 black polyethylene coated Flex-Weave wire
