Web2) The magnetic loop antenna is a high “Q” device, so the bandwidth is very narrow. Even minor frequency changes will require you to retune the antenna, but in exchange the antenna provides superior rejection of unwanted signal reception—giving the best receive gain and the lowest SWR on transmit. Web19 sep. 2024 · Recently Chinese manufacturers have begun producing a low cost wide band (100 kHz - 30 MHz) magnetic loop HF antenna known as the MLA-30. The loop can be found on eBay for under US$45 with free shipping. In the past wide band HF loop antennas have not been cheap, normally costing $300+ dollars from manufacturers like Wellbrook.
