Are magnetic loop antennas any good?
Are magnetic loop antennas any good?
Magnetic loop antennas are your friend. By design, mag loop antennas are some of the best antennas for mitigating the radio frequency interference (RFI) that plagues so many of our homes and neighborhoods. When oriented vertically, mag loop antennas can also be rotated to null out unwanted signals on lower frequencies.
What is the gain of a magnetic loop antenna?
The small loop with its doughnut shaped pattern exhibits a typical gain of 1.5 dBi over average ground and a gain of about 5 dBi when deployed with either short radials (the length of each radial need only be twice the loop diameter) or mounted over a conductive ground plane surface.
What is the best loop antenna for 2 meter band?
144 Mhz Magnetic Loop – A magnetic loop antenna for 144 mhz, two meter band [ Hits: 16129 | Votes: 32 | Rating: 5.77 ] 160/80m Coaxial Receiving Loop Antennas pop – Receiving loop antenna for top band. This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter.
How to build a magnetic loop antenna for shortwave listening?
A well documented plan to build a magnetic loop antenna for Shortwave Listening, includes photos and diagrams. To build this antenna you need a lot that is at least 100 feet across. Antenna covers all bands 80-10 meters + 30, 17, 12 meter WARC Bands
What is a helically loaded magnetic loop antenna?
