10 Meter and 6 Meter Rotatable Half-Wave Dipole Antenna
www.freqdev.com10 Meter and 6 Meter Rotatable Half-Wave Dipole Antenna The half-wave center-fed dipole is one of the most popular antennas in use today. In free space the center-fed half-wave antenna has an input impedance that is a close match to 50 ohm coax and to most radios that …
End Fed Half Wave MultiBand Antennas - W7YRC
hamfest.w7yrc.orgwa7ark 3 What is an End Fed Half Wave Antenna? Let's call it a “EFHW” Works on a similar principle to a Zepp and J-Pole ~0.5 Wave-Length wire on lowest band (130ft on 80m, 67ft on 40m) Fed from one end using a transformer in a box

www.qsl.neta half-wave antenna there is a voltage minimum (node) at the center. The voltage is not zero at its node because of the resistance of the antenna, which consists of both the RF resistance of the wire (ohmic loss resistance) and the radiation resistance. The radiation resistance is the equivalent resistance that would
