Hi, Considering the windinds process for air coil loop, I have being using enameled copper wire. I have seen lots of loop projects basically using standard...
The lower the resistance in the wire, the better. Stranding vs. unstranded only makes a difference if the resistance is lower. Litz wire should be excellent....
... Years ago, I found a huge spool of #16 stranded at a hamfest. Stranded trumps solid any day of the week - construction-wise. My MW 1m square loop of ten...

... I suppose Litz wire could be called stranded wire ... but a very special kind. The 'skin effect' controls the RF conductivity of materials. Simply...
I have recently found and lost a construction article on 20 meter TX small loop made from hard line coax. The author did not use tuning capacitor. The loop was...
... Hi Sarmento, Generally speaking when one wants to construct a tuned loop - or any other tuned circuit - with highest possible Q one wants to use the best...
The only difference making a 20M magnetic transmitting loop with a gimmick capacitor is no different than using a regular capacitor, I have done both. Only...

Hi, An interesting posting on loop antennas. I came across some speaker wire advertised in the UK at £35 / metre ( $63 ) when I saw a sample it was like the...
Grundig YB-300PE AM/FM/SW Receiver + Tecsun AN-200 MW Loop Antenna Package. Both the radio and loop antenna are LNIB and come with all original accessories,...
How do you feed a loop balanced? With what kind of a coaxial can it be possible, with two separate coaxial cables or with one with 2 inner wires? I happen to...
Chris, I think Aimo may be asking about feeding with Twinaxial cable. I'm kind of curious about that myself. I have tons of twinax laying around from an...
... You won't ba able to use Twinax by itself as you'll have a tremendous impedance mismatch. Somewhere, you will need a matching section (single frequency)...
... Hi Aimo, by definition, a balanced antenna is symmetrical ... physically and electrically and does not require ground/earth as a counter-poise. The feed ...
Thanks, Chris! I do not know the impedance of my Twinaxial cable. What kind of a matching section would you suggest? I have used Twinaxial as a loop on my...
Interesting - I found 3 different impedance references for twinas - 78, 95, 100 Ohms. http://www.amphenolrf.com/products/twinax.asp?N=0&sid=4B258000A4B617F& ...
Thank you ever so much for the information, Kevin. I wonder, when I will be able to use the Wikipedia Free Dictionary more(?). I always forget it and make...
Has anyone had any experience with the large ferrite rods and loops offered at stormwise.com? They look like they have some nice toys to play around with? ...
They do have some neat stuff. They have single gang air variable caps for $18 - duals for $40. Times have changed - I haven't seen them anywhere in a while. I...
Hi ! Some time ago I bought variable capacitors from Bebek ltd, Finland. 10 euros/piece. http://www.bebek.fi/kauppa/index2.php You can make web orders also,...
I've ordered a couple of 13.5" 125u rods, and made a really nice tuned ferrite rod antenna for MW dxing. works very well. I used Litz wire to do the windings....

Hello! What kind of variable capacitors do you want? Let me know exactly, and I will try to contact Bebek for you. Please, give a perfect list, so I will be...
