http://websdr.org/ WebThe best antenna types for short to moderate range HF coverage are horizontally- or circularly-polarized antennas that have peak radiation near the zenith. The ground wave radiated by a vertically-polarized HF antenna is attenuated by ground losses and generally not received farther than about 100 km over ground and about 300 km over ocean water.
WebSo, a good compromise for the new HF operator is a multiband antenna that allows operations on a couple of higher bands (perhaps 20-meters, 15-meters, and/or 10-meters), and operation on at least one lower band (perhaps 40-meters and/or 80-meters). Some reasonably inexpensive commercial options with such band allowances are readily … WebHF wire antennas fall into 5 categories HF wire antennas fall into 5 categories 1. Single band dipoles. 2. Multiband Off-Center Feed (OCF) Dipole 3. Trapped Multiband Dipole 4. …
WebSWR at the antenna). This form of matching is more often seen in VHF than HF type antennas, but historically is well represented in VHF dipole configurations. Lumped impedance matching design is of three basic types: series matching, parallel matching (or a combination of the two), and transmission line matching.
