Is a loop antenna for a SWL the best solution?

 Is a loop antenna for a SWL the best solution?

If you dont have a place on the roof or a backyard for a long wire antenne a loop antenna can help you to listen LW, MW and SW.

You loop antenna can be indoor or outdor.

Price start from 40 us Dollars to very expensive prices but when prices are high its because these antennas can be use to transmit on SW bands for amateur radio opérators.

For LW and MW they are indoor antennas, in the past it was possible to find many brands but now only few.

Please reade my articles on this link

https://icomjapan.blogspot.com/2023/10/antenna-is-most-important-for-listener.html


For the shortwave bands 3 to 30 MHz they are a lot of choice.


You can use the loop antenna to listen LW, MW and SW and keep indoor or outdoor. 

The MLA 30 is very popular for listeners because of the cheap price around 30 US Dollars

You must visit my articles ( from my 3 blogs )

You can buy the MLA-30 on internet like aliexpres, ebay, amazon, etc










"So, what is the verdict on the MLA-30? 


Even though the claim is that the antenna is broadband, I believe this antenna has been response optimized for the casual AM broadcast listener.  That is not to say it does not work outside of the AM band.  It will certainly work for receiving signals up to 15 MHz (the point where I stopped the study), but the signals will not be as easy to hear because of the high noise floor and sometimes signals will not be at all intelligible due to intermodular distortion.  Below the AM band, the MLA-30 simply does not work unless the signal is from a very strong station as was the case with my airport beacon test.


If you are just looking for an antenna to listen to local AM broadcasts, at $43, the MLA-30 is hard to beat from the perspective of price. The antenna's ability to null out local noise sources is also a positive for those interested in AM listening.  However, if pulling weak signals out of a noisy RF band is what you are looking for, the MLA-30 falls a bit short of the mark.  In that case, the more expensive antennas like the Wellbrook and  are the way to go."

They are lot of loop antennas for listeners but also for amateur radio opérators. Price can be very expensive

Price can be near 2000 US Dollars !!!



Look expensive LOOP antenna for SWL


For Amateur radio



A nice antenna for amateur radio ( QRP ) or listener 


Magnetic Loop Antenna is one of the best solution for all HAM's or listeners (SWL's) who don't have an access to the large space for the dipole or a long wire antenna, also for those of you who wants to operate indoors of the house, hotel or from the beach on vacation. This Loop doesn't need any grounding or counterpoise and work properly also from a very low hights. The main advantages of my Magloops are: lightweight body, small size, quick and easy setup and possibility to use this antenna also in an indoor conditions.




With a TESCUN PL-330


Paul was a nice sponsor for the SWL contest 2023, he his in Europe. You can visit is web site and maybe ask questions about this loop antenna to use for listening only. 


LOOP antenna from Austalia



In The Netherlands


The AL1 – Built Loopantenna for reception from 10 KHz – 30 MHz

99,00

New! The AL1 –  Kit Loopantenna for reception from 10 KHz -30 MHz.

An active loop antenna for reception, delivered complete with all parts.

The AL1 is a complete kit-antenna for building an active loopantenna for receiving long- middle- and shortwave.

After building all parts on the PCB all you need to do is place it in the housing and connect the loop for operation.




Another shop for LOOP antenna one but i dont know where is this shop !!!




Another loop antenna from Europe

And this one


Have good DX and dont forget i will organise soon the SWL Contest 2024
