WebMF/HF Receiving Wire Antennas Introduction Receiving wire antennas are useful on 160 and 80 meters, where rotatable antennas are impractical for all but a few lucky hams. The noise is so high on these bands that efficiency can be sacrificed with a negligible effect on receive signal to noise ratio. Articles Beverage WebHandheld Direction Finding Loop Antenna for RFI Location Gary W. Johnson, NA6O May, 2024 A good way to locate radio-frequency interference (RFI) in the HF bands is with a small direction finding antenna and a portable radio. Here is a simple antenna design that is effective from 3 to 22 MHz. Based on a resonant magnetic loop, it has high transducer
WebBoth are square. The 160 Meter loop is fed with Open Wire Line and the 80 Meter antenna uses 450 Ohm Ladder line. The ladder line is the typical poly insulated wire with punch outs. The open wire line is home made. Both antennas serve me well. I use a Johnson Matchbox with the 80 Meter antenna and a Palstar BT-1500 with the 160 Loop.
