Does anyone know where I can buy 30 feet of 660/46 Litz wire(solderable)? It's available on ebay, but I would have to buy 60 feet or go outside of ebay to...
Loop Antenna News and Information ForumIs it really necessary to use Litz at those frequencies? Also, why the procedure which uses a rag to wipe the soldered...
Hello. I measured the maximum and minimum band noise of my 1ft dmr loop standing on a window sill. I am living near a HV power line and the attenuation of the...
Hello. I studied the theory and experiments collected by Chavdar LZ1AQ carefuly. Chavdar concluded, that for a loop with diameter smaller tham 1m, the loading...
I know that for a mag loop, resistive losses are huge. Ideally, a single section of soft copper tubing or soldered joints are preferred. That being said, has...

Hi folks - new to the group! I'm thinking of building the varactor tuned loop from Christ Trask's paper "A Simple Varactor-Tuned Loop Antenna Matching Network"...
I have just put up (Temp) my MFJ Hi Q Loop antenna at 6m above the ground mounted Horizontally polarised. I am having great RX/TX with this Antenna. I intend...
I am trying to find out what the optimal load impedance for a small untuned loop or dipole is, but I could not find a definitive answer so far. A simple...
Over the holidays, I took a great deal of time to investigate some ideas that I had with regard to the design of lossless feedback amplifiers in an effort to...
Hi all, this is the group where all the loop gurus lurk, so I think this is the best place where to ask suggestions about this simple schematic of a...
Hi to members of this group. I know it's a bit off topic but it is related to antenna and preamp circuits. I own several ferrite rings that I could use to...
I would like to build a small wideband loop antenna with an internal amplifier. I was wondering if anyone in the USA sells either a kit or a prebuilt high...
Thanks for letting me into the group. I wonder if anyone has measured the input Z to a 1 metre magnetic loop on 7mhz. My measurments show it to be around 15...
If anyone is interest in a MW Band 8" FSL, as described below, which I am asking $300 + shipping for, Then please contacted off list at _everettsharp@..._...
Hi everybody, A little OT but here we go: I think I have Radio Milne Bay on 3365kHz in my headphones tonight. I have watched the PNG frequencies every evening...
Hello everybody. My name is Ricardo. After almost 30 years away from electronics I returned to this hobby. I am a ham radio and also I like DX and SWL. I ended...
Evening Jim I just got a shot of your W5VYY & Edington Loop signal comparison. the blue line shows the signal peaks the yellow was the instant I took the snap...
Some recent discussions about active monopole antennas gave me an incentive to polish off some ideas I had to further advance the state of the art, which...
I am about to build a magnetic loop with soft copper coil and dual stracor capacitor for the secondary loop. I plan to work 7 - 30 mhz qrp with a Yaesu FT...
For the next couple of weeks, a test of a 160 meter Ben Edginton Quarter-Wave loop antenna will be underway. The frequency will be 1900 kHz LSB up until about...
I have just created an album in the photo section and posted a photo of a strange antenna at the Denver International Airport. I initially thought that this...
