160 meter antenna for limited space, the height and width can be adjusted to fit the available area, total length of the wire is approx, 125 feet, the single wire passes through the insulators, the weight must be secured to the wire so that it will not slide

The project included a 40-ft telescoping Tv mast its extended length turned out to be 38 ft

The 160 meter dipole is constructedstranded insulated wire

make a trapped 80-160 meter vertical dipole with the feed point at 11 meters

I managed to locate several nicely spaced trees that looked as though they would serve to hold up a 160 meter dipole, did i mention that we have trees here? lots and lots of trees, in fact, about 12 acres

Large coil added for 160m, note 160m high and low taps at base and 80m high and 80m low selection at top of coil, thick red wire shorts out coil for operation on 40m - 10m

It will still work very good, even if the horizontal wire has to be sloped diagonally to the ground as long as you have enough horizontal space to keep it at about a 45 degree angle or more from the pole

I have been asked many times to explain how to adapt a tunable buried counterpoise system to a horizontal loop nvis

This antenna is designed for stations having a difficult time putting a decent signal on 160m from small garden. it is a 25 ft. vertical antenna, made from three 10 ft. pvc sections bolted together, and 1/2 wavelength of antenna wire helically wound around the pvc sections, a capacitance hat is on top, and the antenna is fed with a 50 - ohm feedline

Antenna verticale in quarto d'onda per la banda dei 160 m che non fa uso di bobine di carico

Aluminum tube for the 160m vertical, it now consist of 24m of wine tower sections and an tapered aluminum tube which is in total 14m long making the vertical 37m high

The capacitor will help raise the radiation resistance at the feed point, for permanent use, we would adjust the value of the capacitor as well as l2 until we optimized the match

How is it good to easily do qrv with a telescoping crank up tower in 160m band? i am troubled with disposal of wires when crank was downed by a normal sloper and shunt feed tower drive, i broke off the problem with this antenna

In total 1600 ft of 14 gauge solid was used in the radial system, resulting in 16 radials each 100ft in length, of the bunch 7 are buried in areas where vehicles and horses roam

As ground net we use chicken-wire which is covering the lot completely 60m x 60m, the conductivity arround every vertical feeding and grounding point more than 30 is improved by copper discs which are interconnected by copper strips, not only the mesh but also the 10 cm wide stripes grew into the earth

The balun i used is an ultimax antennas 1:1 with a 5kw rating so shuld be no issues there

This particular 160 meter antenna looks like a half square, but its radiation pattern and performance is more like a vertical and it is about 40% as big as a half square, if you have about 100 feet or so space it is a viable 160 antenna

Impedance is much lower than 200 ohms, one way to cause the 160 and 80 meter impedances to be about the same is to form the antenna into a right angle as shown below, the 4:1 balun feedpoint is 35 feet from the end

The garden is 57ft 17.4mt wide, the garage lhs is 30ft 91.15mt deep and the rhs is 35ft deep i.e. too small for a 160m dipole, by zigzagging the antenna a horizontal wire of about 33mt

The antenna is sported by a 22ft 6.7m central support and a 12ft 3.66 end support

The dimensions starting at the bottom left of the wire are 30 foot up to the chimney, then 58 foot across to the mast, 12 foot down to the nylon tie and 28 foot back down to the shack roof. a total of 128 foot of wire

The antenna is made for 160 meters and then with the usual formula 142 / freq you get the length of the wire of 77.10 m., but it can also be done, which only reaches 80/40 meters

E' di appena 7,30 mt l'antenna e' composta di un tratto di 4 mt. che è stato svuotato e quindi è solo un tubo di vetroresina ed un cimino di 3,10 mt. che ha l'anima al silicone e quindi conduttore

L'antenna si è ridotta in totale a 8 metri e 80 cm,ovvero circa 22% del quarto d'onda lineare, la bobina di compensazione è stata fissata a circa 32% di altezza dalla base

Le antenne a L invertita sono adottate prevalentemente per i 160 e gli 80 metri le dimensioni complessive possono essere le stesse di una verticale a 1/4 d'onda, anche se il conduttore può venire ripiegato in qualsiasi punto della sua lunghezza

Trovare una valida alternativa al solito dipolo sempre troppo basso per lavorare DX sulla Top Band, l'artenativa tra le piu semplici, vista l'ampia disponibilita del terreno La nostra decisione ricadde sull'antenna verticale o di 1/4 onda, realizzata con pali d'alluminio e filo di rame sorretta da un pallone aerostatico

Sulle bande basse, ed in particolare in 160 metri, e importante poter disporre di un'antenna in ricezione separata da quella usata in trasmissione, cosa assolutamente indispensabile quanto si trasmette con una verticale, che viene definita come un'antenna che riceve ugualmente male in tutte le direzioni

An 80m version 11m in vertical, and 9m in horizontal was, this version allowed me to contact, in 2 x 45mn, 13 stations ja the evening and some stations w6 / w7 / xe the morning

Il dipolo in questione, del tipo caricato, misura circa 20 metri per braccio, è l'unica posizione con cui riuscivo a collocare in modo soddisfacente i suoi 40 metri di lunghezza era in posizione sloper

Dipolo caricato al centro per i 160m di soli 40m di lunghezza,quindi circa il 50% di raccorciamento

This 10 - 160 meter tuned horizontal loop antenna is powered by a 450 ohm ladder line completely in the ham hamlet on a Palstar AT1500BAL balanced line antenna tuner

A full sized, half-wave dipole for 160 meters is rather big around 250 feet long, if you're like me, you don't have enough real estate for that amount of wire! however, you do not need a full sized antenna to produce a respectable, if not good signal on 160 meters

Reduced size half sloper

This paper describes a multi-band DX antenna for the 160m-40m amateur radio bands with low visibility but great performance for long distance communication

A low-cost, low-noise, 21-foot-square receiving antenna that’s certain to boost your DX ability

The total length of each of the radiator halves is about 60 m. they are bent three times, as shown schematically in figure (a), and held in this position by two ends (c) and several intermediate insulators (b), these insulators, like the similar central ones, are made of a non-hygroscopic dielectric material with a thickness of about 5 mm. the distance between the adjacent conductors of the antenna strip is 250 mm

Most 160-meter antennas are big, a full sized half wavelength dipole is about 260 feet long! but with a little creative design work, it's possible to build limited space antennas that will get you on the band without sacrificing too much real estat

This antenna ships 70' in length and will be trimmed back to 68' or less on installation, it works best when attached to your tower/pole at about the 45 50' level, this allows the radiator wire to be angled down toward the ground at a comfortable angle somewhere near 45 degreese

Feed it with a 1/4 wave matching transformer made out of rg11/u, 1/4 wave coax transformer formula = 251/f in megahertz times the velocity factor of the 75-ohm coax, example: 251 divided by 1.9 = 132.1 x .82 = 108.2 feet

The dimensions of 160-meter full size antennas lead you to look for acceptable solutions for their shortening, the author, for example, was driven by the sad fact that a life-size inverted dipole on a tree of reasonable height (12 m) does not fit the roof of a typical prefabricated house

160m is more of a challenge, a simple dipole doesn't fit in your typical yard, a quarter wave vertical requires quite a support structure, what we need is a effective compromise antenna

The dimensions of the antenna are clear from the drawing, with this size, the antenna resonated at 1850khz, using a 12.5 meter telescope, the radiator impedance will be around 12 ohms, but the overall impedance will also complete the earth's impedance, if only 2 or 3 radials are used on the ground, the antenna can be powered directly by a 50 ohm coaxial cable
