MK & TELAMON, My reason for stating that the performance was 'poor' had to do with many small problems: * Learning Curve - It was my first Coax Cable [Shielded] Loop Antenna. * Questionable

I got the copper sheet metal at a local sheet metal shop. It was 4 3/4 inches wide by 8 feet long and I used 5 feet of it for my capacitor. I gave $6 for it. It was in a rack with other bits and

Folks (warning - greenhorn alert) can anyone help out with designs and suggestions for a Tx loop for HF, say 40m to 20m or more? Also how do I calculate the capacitance needed for a specific small

Thank you for the reply. I perhaps should have explained that this antenna would be the first tool used to get started on the hunt for the source of the noise. It would head me in the

I just took a moment to look at your great work on this butterfly capacitor. I'm curious if you could give an estimate on what your materials cost were. I'm trying to determine if this is the route

You do not want to use a Magloop to try and DF power line noise, it won't work! A Magnetic loop is immune to power line generated noise. You can't DF power line noise at all. When you have a high

Welcome! I only joined a few weeks ago myself. So for so good! If you want to build your own capacitor for a transmitting Magloop go to the photo section and look at the pictures in the Butterfly

I read with great interest your email describing your antennas, also read GreerTech Articles. I think you have made a nice job, also by the detailed description on how to build it. Three

Hello all, my name is Jimmy and I just joined the group. I am very curious about the working of loop antennas and hope to learn to build my own. Hopefully this group will provide good data to

BJ, It is my understanding that the Coax Cable Lead-in-Line can not be to long. If as you say, you used good construction techniques and Weather Proofed everything then it should work OK

My plan is to build a loop antenna to use at a fixed location to get a DF fix on local power line noise sources. As a secondary benefit, I would use it as an alternative receiving antenna in the

-snipped great description of butterfly capacitor- Beautiful work! And a great description of the hows and whys of a butterfly capacitor. Yes, it is not possible to link directly into the Photos or

-admin note Please trim your replies... thx- Great Idea! I like it........Thanks ---admin snipped out entire quoted previous message---

FO&A, This Six Foot [Shielded] Loop Antenna has a very narrow NULL Angle +/- 3* to 5*. I live in the SF Bay Area and Nulled-Out KGO 810 kHz 50KW from S-9+20dB down to S-1. KGO=>

I screwed up the first post of this message! Please forgive me <:( Anyway, I can't get a direct link going to the photo section from within a message. I had a good number of replies to my posting

Hello to all, Thanks for all how replied. Did somebody try using the R.F. AMPLIFER KIT on Ocean State Electronics ( http://www.oselectronics.com/ose_p31.htm) ? they say :" A small circuit, using
