160 meter end fed antenna

Field testing has revealed that the antenna works well with or without a ground attached. I discovered antenna computer modeling as an alternative to the cut-n-try methods. 260' is a really bad wire length for an end-fed antenna and a coax transmission line used on 160m. This formula takes into consideration the capacitive "end-effect" from insulators which shortens the physical length requirement for the equivalent electrical length. End insulators are supplied making suspension easy. ... Portable End-Fed / 80-6 Meters/Dipole Antenna/ 300 watts. QSO-KING -- End Fed Multi-band Antenna -- 160-6 meters -- Rated 850 W. PEP !! The 160-meter coil plus an 80-meter mobile antenna were placed at the far end opposite the feed point. The entire antenna is 12 meters long mechanically, but forms an electic length of 20 meters for the 40 meter band because of the coil. Earlier experiments with the 160-meter coil consisted of an end-fed 37-foot rain gutter antenna. June 2018 - Updated January 2019. The antenna This 10 - 160 meter tuned horizontal loop antenna is fed with 450 ohm ladder line all the way into the ham shack to an Palstar AT1500BAL balanced line antenna tuner. I started by pounding a 8 foot ground rod into damp earth at a strategic spot about 5 feet from the base of a tree in my back yard. One end goes straight into the rig, often with no feedline, and the other end in the air attached to something as high as you can find. The above graphic depicts the overall layout of the loop antenna consisting of 558 ft. of #16 "silky" stranded wire cut to one wavelength long on During the PACC 2013 I used this antenna for 160 meters.

The unique design characteristics of this HF JPole antenna enables it to operate continuously from 10 through 160 meters, with only the use of your wide-band (external) antenna tuner. In case of the 10,20,40 meter End Fed, only the first 10,1 meter of the wire will work on 10 and 20 meter. Simply hang the far end from a tree limb–the coax is at the bottom. 4.3 out of 5 stars 53. To make the best use of an End-Fed antenna, it should be fed with a transformer. However, we can reduce the space needed to a quarter wavelength if we decide to use an end fed antenna. They are 6, 10, 12, 17, 20, 40, 80, and 160 meters. Add to Cart; RW Antennastore WORLDS BEST 80 Meter Half Sloper End Fed Ham Radio Antenna 1 $89.00. 9. Add your 50 Ohm coaxial feedline, counterpoise, suspension rope and go. On a 9:1 end fed, the coax is an integral part of the antenna and radiates about as much as the wire. 22 Different Wire Antennas for the 160 Meter Band for the 160 Meter Band Random Length Radiator Wire Antenna Delta Loop Antenna Half Delta Loop Antenna Off-Center-Fed Full-Wave Doublet Antenna Terminated Sloper Antenna Double Extended Zepp Antenna 40m - 80m - 160m Short Dipole Antenna 10m … 468 ÷ freq (mHz) = Length (feet). 6-160 Meter J-Pole Jr 34 foot End Fed antenna Posted date: July 19, 2016 in: News No Comments A combination of antenna designs, namely the J‐Pole and Zepp along with Alpha Antenna’s matching network technologies, are utilized to achieve a fairly resonant antenna design that can be tuned on 6, 10, 12, 15, 17, 20, 40, 60, 80, & 160 Meters. Sometimes on 80 meters but there the 80 meters 2 * 20 meter dipole fed with open wire gave me more qso’s. A standard recommendation (see QST, March 1936, p. 32, "An Unorthodox Antenna") is an 84' long end fed … Manufacturers of High Quality HF END FED Wire Antennas De trendsetters van de eindgevoede antennes sinds 2006 . The result is a "hybrid" dipole or "ungrounded" vertical amateur radio antenna, depending on your point of view! Hang it up in a hotel window or string it up in the attic. End Fed Halfwave. This antenna is a half wavelength at the lowest frequency of operation, and then as the other bands on which t can be used are harmonically related, it provides a multiple number of half wavelengths. SWL NOTE *** A wide range tuner may be needed to tune this antenna to 160-6 meters. I am not a mathematician that calculate ohms, coils etc. $99.00. The black dots represent exact harmonics of the 3.57 MHz fundamental resonance. The basic formula for determining the length of a center fed, half-wave wire Dipole or Inverted Vee antenna is:. I test on the fly and learn from that. Below the antenna used during the PACC 2013. So do all antennas, but not at the design frequency - there, at the design frequency, the terminal impedance is quite predictable. The feed point is just outside my basement shack window, about one meter (3 feet) above ground. The OCF160 covers the following ham bands. If you are limited on space to hang an antenna, but still want to use all of the HF bands, thenthe"QSO-KING" is a good choice for you. HyEndFed® The Ultimate Wire Antenna sinds 2006 .

In reality, it's probably several thousand Ohms. $81.99 $ 81. - End-Fed antennas have wild impedance swings. The antenna is fed about 87 feet in from one end of the antenna. Free Shipping by Amazon. Can be used as a end fed shortwave antenna to provide continuous coverage from 500 kHz to 60 MHz. More coax is good in this case because its more antenna to radiate. 3. However, when I operated on the lowest ham band, 160 meters (1.8 to 2.0 MHz,) performance was sub-par, since the dipole was only 25 feet above the ground, and that’s just a fraction of a wavelength on 160 meters.

An end-fed 1/2-wave reflects its termination impedance back to its feedpoint. That meant most of my signal was going up, not out. Before I added 80 meter, I operated that band with a end-fed wire antenna. The key to end fed antenna success is the matching network interface between the long wire antenna and the coax feed line and feed line choke at the transceiver. End fed half wave antenna: One method of providing a multi-band antenna for the amateur radio or ham bands is to use an end fed half wave antenna. It is important to use a counterpoise.
