Does anyone have any experience with either of these coverings? *Can

IIRC the PAR EF-SWL Antenna uses Flexweave
as the Wire Antenna Element : Had one out for
many years (7~10) and it works well; the the
Flexweave wire has held-up a-ok.


-just-looked- Par Electronics EF-SWL Antenna
{End-Fed Short-Wave Listener Antenna}http://www.universal-radio.com/catalog/sw_ant/2205.html
Uses 45 Feet of #14 Black Polyethylene Coated
Flex-Weave Wire made-up of 168 Strands of #36
AWG Woven Copper.http://www.grove-ent.com/ANT8.html


First had it as a simple Inverted "L" Antenna with a 15-Foot
Up-Leg {Vertical} and a 30-Foot Out-Arm {Horizontal}.
Later changed it to a Off-Center-Fed* Dipole with a 17-Foot
Short-Arm and a 28-Foot Long-Arm.


* The PAR EF-SWL's Matching Transformerhttp://www.parelectronics.com/pdf/EF-SWL.pdf
allows it to have the two Windings shorted together
with a Common Ground for an Inverted "L" Antenna
-or- Separate for a 'Floating' Two Terminal Antenna
Winding for a : Dipole; OCF-Dipole; Windom; Loop; etc.


-imho- the 'flex-weave' is good stuff - iane ~ RHFhttp://www.davisrf.com/flexweave.php

Thanks Roy. *I'd get the PAR, actually, except I am hoping for
something just a bit longer (~30 up, 60 horz). *I will put the match
at the ground rod. *Thinking of getting theWinradiomatchbox, which
also uses the binocular ferrites and a metal case for strapping to the
ground rod.

I may end up getting the PAR and trying it as a sloper from near
ground up to that 30 foot height...then running both of these through
my MFJ noise canceller (which actually works, but really needs two
pretty well-matched antennae). *With my horrible RFI situation, I am
beginning to run out of ideas, though - if all of this fails, I might
try one of those expensive vertical magnetic loops on a rotator, but
that will be a last straw.

BpnJ,

I presently am using both the WinRadio [$40] and
the RF Systems MLB [$75] Matching Transformers :
Last year I 'switched' the two of them around on the
two SWL Wire Antennas here. I could not tell {hear}
the difference from before and after the 'switch'.
