End-fed antenna for 80 metre operation The physical length of any HF antenna is critical to achieving resonance and good performance on a particular band. Dipoles need to be half a wavelength long, locating these long antennas can be an issue, especially when we are aiming for the 80 metre band or lower. Portable End-Fed 160-10 Meters Dipole Antenna George on 24th Feb 2020 This is the 4th or 5th product that I have purchased 4 or 5 items from ni4l. Once again the antenna was shipped and received with in a few days. This antenna works quite well no issues. "EFHW" - the end-fed half wave antenna. Introduction. One of the cautions you sometimes see in discussions of the end-fed antenna are "avoid multiples of a half wave." The very valid reason for this is that the high impedance of the feedpoint was outside the range of most transmitters and external tuning units. antenna Norfolk Amateur Radio Club used for its International Marconi Day (IMD) operations at Caister Lifeboat this year. Ten Megahertz (30m) turned out be a useful band for us, allowing CW contact after CW contact, despite poor conditions after a geomagnetic storm and a K index of five. The antenna we used was a portable multi-band end-fed ... EF SWL. The Par Electronics EF-SWL is an end-fed short wave antenna optimally designed for 1-30 MHz reception. The radiator is 45 feet of genuine #14 black polyethylene coated Flex-Weave wire. Of course this is only an issue if you want to feed the antenna with coaxial transmission line without using a tuner at the radio. In the old days, the antenna would probably be fed with open-wire line, and this antenna could be easily tuned from band end to end. One of the most popular antennas today is the end fed antenna due to it ease of installation, portability and stealth in various installations. It can be a condo dweller’s only access to the world of ham radio or the best alternative for a backpacking SOTA (Summits on the Air) mountaintop expedition. We continue our antenna offerings with this single band, 80m-10m end fed half wave wire antenna. It is designed as a highly portable wire antenna, easily set up as an inverted V, horizontal, sloper, or in the case of higher frequencies, a vertical radiator. Your feed line is essentially the counterpoise, so a separate one is not needed. end-fed As high as you can get it, but no fixed figure Has good DX from the vertical portion Has good NVIS from the horizontal portion You can bend the hot end to fit into gardens less than 60ft – but keep clear of the ground (people) and anything it can couple with ( like phone lines!)

Sep 03, 2016 · If you want an end fed for 160m that actually works well you would go with a full 1/2 wavelength of wire (about 250ft) fed with a transformer that has a very high impedance output to match the 1/2 wave end fed. Several companies make the transformer and complete antennas and if you have the space you will be rewarded with a good performing antenna. surface of the conductor. A practical half-wave antenna made from wire needs end supports; each end usually being terminated with an insulator. The capacitance between the ends of dipole and its supports, even when the supporting material is non-metallic, gives rise to end effect. This effect additionally loads the wire capaci- Apr 05, 2019 · Unfortunately I don't have another 80m antenna to run some A-B checks with but from what I can tell, performance on 80m seems to be good. If you are on Facebook, there is a lot of good discussion and information available on the End Fed Half Wave Antennas group. I have very little space to lay radials on our city sized lot. Since a vertical (Inverted L) is really a end-fed antenna it requires some form of path for the return current which typically is either an elevated or buried radial system. A properly constructed FCP can also serve this purpose within a total length of only 66 feet. We continue our antenna offerings with this single band, 80m-10m end fed half wave wire antenna. It is designed as a highly portable wire antenna, easily set up as an inverted V, horizontal, sloper, or in the case of higher frequencies, a vertical radiator.

Please email me with any questions." Fact is, if you can effectively couple RF current into something that's large relative to the wavelength and is a good conductor, you get an antenna. The bigger problem with end-fed antennas is subtle: it's actually only half the antenna. The ground is the other half, and I don't mean Earth. Centre fed half wave dipoles make great, simple and effective antennas for the HF bands. Sometimes however, the centre feed is not ideal, for example when you want to use it as a vertical. Being able to feed the dipole from one end gives you more options on how to erect an antenna and makes portable operation easier. End-Fed Antenna Class – May 2015 The Tri-County Amateur Radio Club – WC5C held an Hawaiian end-fed antenna building class at the Azle Fire Department on 16 May 2015.

The antenna has a full 300kHz bandwidth on 80m between 3:1 SWR points. But performance is down about 8-12db on a dipole on ... rather than supported at each end with a big droop at the center (current point nearest to ground). This is another reason for not being too fussy about the ends of a center-fed antenna being lower, or bent around. It will have minimal effect on radiation efficiency. The main thing is never have the ends dropping right down to ground One of the most popular antennas today is the end fed antenna due to it ease of installation, portability and stealth in various installations.
