The lab instructor told me to just use a single monopole antenna. Though I'm not sure if I can do it with a small loop antenna, it's enough to go off of after seeing his demonstration. I just need to properly handle and filter the signal. AM radio broadcasting uses amplitude modulation. Because of AM radio's low frequency and clarity, it mainly broadcasts news, talk radio and sports shows. Let me show you how you can make a loop antenna at makearadio.com, Dave Schmarder's radio hobby website.
This preamplifier is generally used with receiving antennas (Dipole, Loop, Long Wire, Beverage, etc) in the amateur radio bands (160m, 80m, 40m, etc). This preamplifier is also be useful for regular commercial shortwave radio reception. The Loop Antenna Amplifier is to be reviewed in the March and April issues of Radio User magazine. Here is a link to the preview web page. Here's a video of the prototype of the Loop Antenna Amplifier in use with a loop made out of a 700C bicycle wheel rim. The video is made during a field test in a very quiet rural environment.
Cut an appropriate length of twin for the top bar. In the middle of that length cut one of the two conductors and strip back the plastic coating. Now connect another length of the twin lead to the two bare conductors of the top bar. The other end is connected to your radio antenna terminals. A loop antenna is made up of several turns of wire around a form. The larger the form, the more wire you can use and the more sensitive the antenna will be. It becomes important with a loop antenna to allow ample spacing between the turns.

Several years ago, I became interested in medium wave DXing. I may make another tuned loop using two crates to see how much more gain I get with the larger aperture. Happy DXing, James Townley.
Antenna Analysers - How to use them and what the readings mean. by ZS1JHG. Antenna analysers are handy test instruments for finding out how well your antenna is performing. How to use them: Always short your antenna leads before connecting to your Antenna Analyser. The zero bias bridge diodes are easily damaged by static. You have been warned!
  • Project airbus a320 repaints1. Connect a coaxial cable between the antenna preamplifier and the coupler interface box. Connect the supplied jumper between the coupler and your receiver. 2.

  • Retro supply companyThe method described here can work for making a loop antenna without the cardboard form. The method involves placing some duct tape sticky side up on your work bench. Use some more tape, staples or thumbtacks to hold it in place. Use a Sharpie pen to sketch in about where the center area of the loop should fall.

The active loop antenna can be installed close to a transmitting antenna without a problem. PA3GZK use the transmitting antenna 4 meter away from the receiving antenna, which is still intact despite sometimes 1 KW transmitter power. resonance. My antenna had a very good match on 40-15 m with the SWR below 1.3:1. It was higher on 80 m, around 4:1, but this is perfectly acceptable. Using the Antenna You can use any kind of portable radio that covers the shortwave bands for RFI hunting. AM demodulation is preferred. I use an old Radio Shack DX-398 that I found on Ebay. If
