Thanks, Bruce 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. Bruce Bruce 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'. |

We already have the ability to look **** up ourselves. 99% of what you post is irrelevant. You are a mind****er. If you had been in Nam they would have fragged you on the first patrol. Hey! Jared! I thought they had your sorry ass locked up! |
