Re: [Elecraft] Mag Loop

I built two mag loops, one with an MFJ butterfly cap, and one with a massive 60pf bread-slicer I found on Ebay--if my calculations are correct, the monster should take a kw of power on 20m. The MFJ capacitor is not high quality, but it works over a wide range. However, I much prefer my AlexLoops

Re: [Elecraft] Mag Loop

I made a small transmitting loop a couple of years ago as an experiment with a material I wanted to try. One of the materials was not appropriate, but I made it work for the sake of the experiment. I plan to make another loop at some point from a different material so it's not an issue, but that

Hi Group: OK... here's my mag loop story: I have two AlexLoops and one is the original version that uses copper tubing for the main loop.  I used that loop to make an RTTY QSO with a station in Moldova.  I had set the loop up indoors (in my sunroom, which has a lot of windows) and worked

Re: [Elecraft] Mag Loop from MFJ

FWIW - I invested in an MFJ-1786 when we moved into our apartment 6 1/2 years ago. Since then, kit has been out on our 5th floor balcony in central Minneapolis year round, easily standing up to both Minnesotan Winters and Summers with aplomb. It has not ceased to work in that time and has

I can’t speak to the MFJ but I do have a 3 ft diameter AlexLoop that I imagine is similar at a very high level and in addition as M0SNA I have the Ciro Mazzoni Baby Loop which can handle a wicked amount of power and is built like an Italian sports car. One thing that surprises me about magnetic

FWIW, mine has worked fairly well (on the roof of my second floor condo) since last year, moreso on 20 than 40 meters. At the time I was honestly not sure how else I'd have been able to have something permanently set up outdoors (unfortunately needed due to stucco construction) and HOA approved

Re: [Elecraft] Mag Loop from MFJ

Ciro Mazzoni loops run from $1,800-$2,500 at DX engineering.  They seem to use direct in place of inductive coupling.  The automated tuning is cool, but requires a control cable to the antenna as well as coax.  My experience with MFJ resembles Morgan's, I wouldn't call them junk but they don't

They are unreliable pieces of junk. The housing does not protect the capacitors that are in house made and bugs can crawl into the housing and short them out. Secondly, the plastic housing in Kansas will be destroyed by the sun. The best thing about the loop is the loop itself. It is built well.

The Alex Loop is rated at 20 watts PEP maximum. Even at 5 watts, I position mine as far away from my body as I can. The jury is still out, in my opinion, as to how RF affects the human body, especially the brain. 73, Kent Trimble, K9ZTV Jefferson City, MO On 1/23/2017 1:11 PM, someone

Well Morgan ... Your fluorescent bulb is responding to the voltage/current nodes around your octagon. Your loop is coupling to free space using the H-field, to which the bulb is pretty much insensitive. Because an electrically small loop couples via the H-field, it tends to be fairly
