Webhalf-wave antennas. An end-fed half-wave (“EFHW”) antenna has a very high feedpoint impedance, often 1000 to 5000 ohms (depending on the diameter). The radiation pattern on the fundamental frequency (where the antenna is 1/2 wavelength) will be similar to the same wire fed in the center as a dipole (but this is not the case on harmonics). http://www.n6cc.com/end-fed-half-wave-wire-antennas/

WebIt could also be viewed as a 160m off-center fed dipole antenna... with its long leg going up vertically, then away horizontally - and with its short leg lying flat on the ground and insulated from ground electrically! In fact, it looks more like an end-fed 1/4 wave 160 meter antenna (130 ft or 39.624 m long) which goes up some 25 feet (7-8 m ...

Single Wire/End Fed Antenna - K7MEM
WebMar 29, 2024 · Last week I received the KM4ACK EFW (End Fed Wire) antenna and assembled it. Had to wind the 49:1 balun and assemble the parts onto the supplied Wire Winder. Came with 65 ft of wire and BNC connector (optional as to what connector you order). Took it and my IC705 to local park and I was impressed with the antenna’s … WebCurrent Balun 1. Un-Uns for Endfed-Antennas (EFHW) by DK7ZB. Wire antennas with an Un-Un-transformer 1: 9 have become more and more popular. This is based on random lengths of the antenna, which is transformed with the un-un into a medium-ohmic impedance range with reactive components. This can then, fed with coaxial cable, in … WebMar 10, 2010 · Make sure the first wire is wrapped evenly around the whole toroid. On top of the first wire, wrap a second one around the toroid three times (I used a red wire for this). Also on top of the first wire, wrap a third wire around the toroid four times (I used a black wire for this). 2. Connect a binding post to each end of wire 1 (these are not ... terminal kampung rambutan ke bandara soekarno hatta
