Has anyone reverse engineered the Wellbrook Loop and setup a similar DIY formula for building your own, perhaps of copper tubing ? Also a schematic for an amp...
Sorry about the spam that slipped through. FYI, I'd prefer that if you see spam on the list, in the files, links, calendar, database, etc. that you NOT post on...
Has anyone measured IMD of a balanced loop amplifier? The main thing I'm trying to figure out is how to couple the test signals into the balanced amplifier...
Well it seems my original question got lost in the static, so I'm going to try again. I would like to know if I want to build a multi turn loop. The loops...
It's interesting to see glimpses of high-tech manufacturing up close, most of us don't know how such things are done. Also interesting to see a line of...
Starting out now to build my first shortwave loop in 30 (honestly!) years. My plans will put 3 turns of wire on a square that is 18" on a side, for a total...
This is to be a receive only direction finding loop, that I plan to use to chase down some local power line rfi, that is interfering with my reception from...
Hi all, I am newbie of antenna fabricate! I would like to design an log periodic loop antenna. Each dipole element in log periodic array are replace by a full...
I want to use a bipolar stepper motor to control tuning cap on a loop project. I would like manual control of speed and direction as well as single step use....
I have a Globe Traveler G3,(AM/FM shortwave Radio with SSB and RDS ) and I would like an antenna to compliment the radio. I have limited knowledge when it...
I have just joined the loopantennas. I joined to learn how to make an antenna to be able to receive AM signals out of Chicago. There is a station that...
Loop Antenna News and Information ForumI'm fairly new to the group, but thought that this link which appeared in a message on the ultralightdx group might be...
Hi, Anyone interested in the art of ' Lowfing ' with loop antennas this website is well worth a look through, a.. 136 kHz technical pages (homebrew stuff) 20...
I was working on a new loop antenna for my KA-35. If you have a KA-35 you can take a 470 pF capacitor and solder it to a left channel connector to any tunable...
Hi: If you are wishing to create a termination load for a Rhombic Antenna, you need to have something that will take 50% of the power you intend to transmit....
Looking for "economical" sources/leads to buy non-inductive 2-10W terminating resistors for T2FD/Rhombic type antennas. Any designs on making a loop...
Hi, I´m noob in loop antennas and would want to know if, is it possible to replace the original loop antenna of degen de31ms by copper pipe? Sorry for my...
I have a couple of questions for the group. The fIrst question is around the construction of a loop for my Wellbrook ALA100M. I've been dabbling with a couple...
Thanks everybody for your considered replies. These are just the "pointers" and suggestions I was hoping for. Great & helpful group! Have a great day all, ...
Greetings all- I am quite new to loop antennas and have decided to jump in and get wet by building a ferrite cored loop similar to ) what is shown here: ...
Hello All, Well, as Yogi Berra said "Nostalgia ain't what it used to be". In spite of that, I've been bitten by the ham radio bug again after an absence of...
I saw a reference in the ARRL handbook to a aperiodic loop and from what they show, it appears to be an unbalanced loop with a loading resistor of some...
Anyone have experience building an aperiodic receive loop? I am trying to understand how to choose the value of the loading resistor. Thanks, John McKee ...
Hi all, Yet another apartment owner looking for a compact antenna. I've done some reading and I've gone through most of the files in the "Files" section of the...
Hello I am about to mount 2 Wellbrook loops on one pole, a 1010 & 1530. I understand this is possible but are there considerations I should take account of,...
Hi, There is an interesting variation of a MW loop antenna on the same website as the magnetic loop, www.rsars.org.uk/ELIBRARY/docsants.htm - Cached - Similar ...
