Cebik, W4RNL (SK) In Parts 1 and 2, we examined the simplest unterminated and terminated long-wire arrays using a single end-fed wire in both cases. Unterminated wires yield essentially bi-directional patterns in line with the wire--more in line as the wire grows longer as measured in wavelengths. A simple 1 line schematic drawing might make the AM antenna text a little easier to understand. (Or a photo of the entire antenna with it's connections.) Reply. keith hayes. ... Try this: buy a spark plug and connect your long wire antenna to the "hot" terminal. Using a couple of washers and properly sized nut, attach a ground wire to ...This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It is similar to a G5RV but a much better performer especially on 20 meters. 40 thru 10 Meter Zepp AntennaThe W3EDP antenna was first described in the ARRL’s QST magazine in 1936. One such antenna is the W3EDP end fed. It consists of an 85ft wire fed against a 17ft counterpoise (attached to the earth point on the ATU). Some books say that you don’t use the counterpoise at all on 10m. Others say that you can use a 6.5ft counterpoise on 20m. Step 1: cut the wires to length This is easiest to do with a wire measuring board. I'm going to build the dipole for 14.1 MHz, and I think I will need 5.25m (17.25 feet) of wire for each side. But I'll cut the wires to 5.5m each instead, to allow some length for adjustment. Determine the wire length for other bands here.MLA-30 Loop Antenna Active Receiving Antenna 100kHz - 30MHz for Short Wave Radio 101 1 offer from $47.69 Tecsun AN-48X Indoor Active Loop AM/LW/SW Radio Antenna 351 3 offers from $34.99 CC Shortwave Reel Antenna 401 2 offers from $14.994.

Safely throwing a rock over the branch or casting a fish line can work.Long wire or random wire antennas are very simple antennas. They can come close to half wave antennas in efficiency, although efficiency decreases as they are made very long or installed closer to earth. Like every antenna that exists, random or long wires have advantages and disadvantages. Shop for 2 Meter Antennas here. This antenna is similar in construction to the 2-meter OFC sleeve dipole I built over 8 years ago, but it is a simple center-fed dipole. I used 1″ thin-wall PVC pipe, aluminum tape, and RG-8X coax. The goal here is to put up a cheap, easy, and quick 2-meter antenna that is simple and unobtrusive, but works ...Generally the longer the antenna wire the better so if you have a 100' antenna wire, that's good. 2. The other end (not shown) of the coil will go to the ground stake so leave enough wire. The ground stake can be driven into a convenient and safe place nearby. 3. For maximum reception, stretch the antenna wire out perpendicular to the station ...Long wire or random wire antennas are very simple antennas. They can come close to half wave antennas in efficiency, although efficiency decreases as they are made very long or installed closer to earth. Like every antenna that exists, random or long wires have advantages and disadvantages. Advantages. Disadvantages. 3. A random long wire is just that, random. While large loops at the end or bending the wire might change the resonant frequency, a random wire isn't (unless by chance) resonant anyway. So loops and bends just make a different random wire antenna which is neither better nor worse. The shape of the antenna isn't going to affect efficiency directly.Step 4: Measurements. To check the transformation ratio of 1:9, the balun has been measured with a VNA. In this measurement the balun is connected to a 470 ohms resistor (the impedance of the VNA port is 50 ohms). As we can see on the picture, the balun assure a bandwidth going from 3 MHz up to 50 MHz with the respect of SWR of 2:1.These inventions simply use the ever popular 300 Ohm antenna lead in wire. You can use them for any frequency, including the HF bands, but you will need a tall tower, or a high tree to hang them high in the sky. As of this writing, 300 Ohm antenna wire is pretty scarce. A roll of 300 or 450 Ohm antenna wire was $55.00 just a year ago.Sep 02, 2006 · Long Wire Antenna for CB ~ 11 Meter Use. An Article Written By Tech237 ~ Simon The most practical and simple to make Long Wire Antenna is the resonant variety. A resonant long wire only requires that the length of the wire is approximately resonant at the frequency of operation. For CB this means the wire must be a multiple of 11.1m or 36ft 6.5 ... The end fed wire regardless of its length presents a high impedance to the feedline. If the intention is to build a ½ wave mono band antenna then it is necessary to attach a 48:1 unun at the feed point given the extremely high impedance. But if it's a multi band antenna and is not ½ wavelength long on any of the intended bands then a 9:1 ...A long wire antenna is a type of antenna in which the length of the wire is usually greater than the length of the half-wave dipole i.e., λ/2. These are also known as harmonic antennas. It offers operating frequency range between 500 kHz to 30 MHz.

The easiest way to obtain more gain is to take your basic dipole and extend its length to about 1.28 of a wavelength overall (0.64 for each leg). This is known as a Extended Double Zepp (EDZ). June 21, 2022 Long wire antenna build Installed with a proper ground radial or counterpoise system, a random length long wire antenna makes an excellent temporary or emergency antenna. In this video, Jez (2J4EZ) takes us step-by-step through the design, construction, and testing of a long wire antenna.An end fed half wave wire can present a feed point impedance of 2500 Ω or more. That's a 50:1 impedance mismatch for a 50 Ω output radio (SWR of 2500/50=50:1). A typical ferrite core transformer as above with a 7:1 turns ratio (49:1 impedance ratio) or more will be "helpful". As an example, on 80 meters, with the radio or feed point on ...The wire should be a minimum of 65 feet long because it works well but the full 100 feet is better.
