Bob, N1KPR <rwbetts@...> updated the album Triple-shield Passive Broadcast Loop ( /g/loopantennas/album?id=281378 ) : Good signal, good nulls

I uploaded a triple shield passive loop that is a common monitor antenna for b'cast stations. I use it with a 15-20dB preamp for home entertainment. That gives a signal strength equal to my 160-meter

searching for a passive? receiving shielded loop for medium wave broadcast band have somebody a design? thanks in advance rinus

There's more that I want to add to the v2.0.6 update than just the Q calculation fix, mostly related to a configuration panel, plus some additional refinements to improve accuracy. Rather than wait

I guess they're stripping attachments. The two pictures I referenced are now in my Dropbox: https://www.dropbox.com/sh/x76xut9sdfps58j/AACE1zCiHmBZxV0miWShc1Raa?dl=0

Thanks to Roger for pointing out the review by Owen Duffy. I have been a fan of his work for a long time and it saddens me that I messed up one item in the recent updates to my program. For a long

Owen Duffy has made numerous posts about loop antennas on his site and has developed several loop calculators.? He recently wrote a review of STLcalc 2.05

Over the past several days I have been asked by some users of my STLcalc program why I have not responded to a rather snarky email to the loopantennas reflector from Jim, AA5CT. For the same reason I

Start of reading Gentry’s paper from page 26 to understand the matching technique proposed. Talking about the radiation efficiency for small antennas the value is low and there is no improvement

Although Gentry uses the term "matching", I don't see his method optimizing the power transfer or achieving the impedance matching on either end of the network. It only generates the desired frequency

All, For an illustrative purpose you may read De Gentry's work about the broadband matching of a loop antenna but the calculated by him filter elements you cannot use because he designed his filters

Thank for the response, Jef. I will follow that link ! Michael 2E0IHW

Good morning Michael, If you google the thesis about" broadband matching of a loop antenna by De Gentry" you will get a lot of actual filters with values for the parts and a performance curve for

Some of us,? maybe only me, would just like to know what works best and how to build it ... Ouch, Michael ...Can you give an example of a passive network that can match a small loop to a 50Ohm load

For those of you that are interested in matching a small wideband loop antenna there is an interesting article ( actually a thesis ) from 1966. The paper describes the use of a low pass filter that is

Chris Trask's 2008 paper "Wideband Loop Antenna Matching" is a good starting point. https://studylib.net/doc/18352805/wideband-loop-antenna-matching-networks The implementation is rather more

Mike, I do not want to sound rude but there are many sources in technical literature where you can find how to calculate elements of broadband filters based on the source and load impedance and

Hi Raphael, Thanks for your reply and comments. I need to spend some time reviewing them in order to better understand the points you are making. I think my main problem is differentiating between
