The only thing I forgot to do was change the Mode from USB to AM. But the Mode makes no difference when using the fine tuning - as you saw in the video, below 30MHz the LA-400 performs exceptionally well bring in deaf signals to very strong signals without the loss of audio quality.
@@xmenken1 yes it is. People hang shortwave loops outside their apartment window all the time. I know a guy who does it with an AN-LP1 Sony and Tecsun pl660
I don't have access to any other antennas. I believe the video demonstrates (for me) how well the LA400 performs below 30MHz. You can see in the video how the LA400 brings to life transmissions that otherwise would not be seen or heard. There are many videos you can watch of other antennas and from those you can decide whether or not the LA400 is good/better or worse. I am considering getting a K-180WLA 0.1M-180MHz Active Loop so you might see a video of that and would then include differences between the K-180WLA and the LA400.
The equipment is free of any dust particles; the focus is perfect; the audio is excellent; the silent demonstration is rigorous . (... But where did you put the antenna?)
The 'Loop' was hung on a window (north facing) via 2 meters of custom made standard RG58/U coaxial cable. The mistake I made in the video was to stay tuned to USB when the receiving Mode should of been AM -- however, it made little difference to the receiving reception and the operation of the AOR LA-400. A later test of the Icom IC-R8600 was made when connected to a Wellbrook Active Loop Antenna Model ALA1530LN. Unfortunately, on that day and test the Wellbrook didn't perform as good as the AOR LA-400.
For my part, I received the AOR LA 400 late afternoon today, with a 10m extension cable set (LA400-RCK) . My pleasure will be delayed by another 24 hours, i.e. until delivery of the appropriate BNC-SMA / BNC-UHF adapters for my RSPduo SDR and my rig. 73
@@jean-pierreemilien1404 Oh my!! Why have you bought the LA400-RCK? Are you aware of the price of the LA400-RCK? If you read the manual, on page 9 (5. Remote Tuning System) it says "You can of course use generic straight LAN and RG-58U 50Ω coaxial cables. Maximum length: 20m each". Do you actually need 10 meters? You can buy your own coaxial cable from eBay or any store selling coaxial cable -- as long as it is standard RG58/U cable, that's ok AND as for the power cable extension, that only has to be a standard network cable -- both cables can be made to your exact length. I made up my own extension cables and cost me around £12. About 40% of the cost was postage cost.
The antenna was detached from the Base and hanging 3 meters away under the window reveal. It is best not to hang the Loop on a hook on the glass as the glass affects the receiving signal. It is best to hand the Loop about 4 inches away from the window glass.
AOR LA400 loop antenna is pretty expensive but it works well in your demo.

@Maersky , Icom IC-R8600 is a beautiful machine as well.
Ken, where can you get the AOR LA400 in Hong Kong since I would like to get one here.
@Andy Chiu , I have no idea. Hong Kong is a crowded city. It is not even possible to put a TV antenna outside a building.

How does it compare to other antennas? Detuned vs detuned doesn’t provide a good idea of how well it actually works.

@@jean-pierreemilien1404 it comes with the extended control cable as well so it’s fine.
Hi, where was the sa 400 loop located? Thank you...

@@Maersky-747 really? I never had any issues with my loops on glass windows.
