Web11 mag 2024 · It's for 915 MHz but the principle is the same at HF. A good ground screen will be required. There is also a half-log-periodic antenna, sometimes called an LPMA. It's a fairly standard thing at HF, but takes up a lot of room for hams. Here's one from R&S for 1.5-30 MHz, 97 m long and needs a 90 m mast. WebHF. ANTENNE DIRETTIVE HF. ANTENNE DIRETTIVE HF.

WebAlso, read the section "Bidirectional Antennas" in Chapter 12 (page 12.14.) Background: Gain! Oh, boy! No word evokes as much interest in the antenna designer. An antenna with gain seems to give its user something for nothing--more signal with no extra electricity required. Even better, when the antenna is a simple combination of wires.
