First off, congrats on "homebrewing" your own antenna as well as having done some research on how and why a loop antenna can help in your reception. I believe there is a budding amateur radio (ham) operator in your future! Many hams LOVE to build their own antennas, me included.
What kind of reciever are you using and what type of antenna jack, terminals, or connection does it have? That will be the determining factor on how you can bring your new receiving aid into use at your station.
Your loop will help in a number of ways. For some reason I am unable to explain, loops "hear" better at frequencies far lower than it's resonant frequency. It also enables the listener to set it up vertically and then rotate it one direction or another to either make a desired station louder or "null out" an unwanted station or interference. This is especially evident in North America for SWL's to "null out" a loud North Aamerican station and listen for European stations "over the pole" because EU stations are assigned what most NA stations consider as "oddball" frequencies. They can do the same for ours. I worked at a radio station in Tennessee once and they also had an automated country station that ran low power (1 kW) at night. They would recieve MW SWL reports by mail for QSL cards and had no idea what to do with them. These reports were from all over Scandinavia.
