Wich is the best 160m antenna ?

QRZ Forums. Wich is the best m antenna? Hi all, In your opinion wich is the best m antenna to build. Long wire's, beverage?? I would like to hear your opinion's and if possible with a link to how to built one. CU3AKAug 20, NY4QAug 20, Yes I want to work DX. I will try to input more power. But the reception is also weak. I bielive I can extend a long wire across the house to some fields I have nearby. Here's a good site for building your own antenna's of many kinds. Top or a hillbottom of a valleyhow big is the field etc. Kinda like the 1st postmultiple is great if you canand the bigger the better. Consider an extended double zepp if you have the room. I have had outstanding results with mine. Just Google for plans. If you want to work DX onI'd recommend something like inverted L. Put down a decent ground system and it will outperform a low dipole almost all the time. If you have problems receiving weak signals then you will also need a receive antenna. The receive antenna is usually not much good for transmitting. Loops pennants, flags and beverages all have their place as receive antennas. The majority of DX on is on CW. There is some on SSB, but it will be easier to hear in the wintertime as the atmospheric noise from lightning QRN tends to be less. K8PG likes this. A vertically polarized antenna with a good ground system will work much better than any horizontal antenna. An Inverted L is one of the best ways to make a good transmitting signal, so long as you have a good ground system. For receiving, a Beverage is simple and easy and very good. If you do not have the room for a beverage, then some small loops will help. Look at K9AY and Flag antennas. Since you cannot have much height, a dipole would be as good or better than an extended zepp or big horizontal loop. Nothing will be as good as an Inverted L or another good vertical for transmitting. W8JIAug 20, There's just about as many ways to build an antenna for as there are for any other band. Beverages are really, really long, and if you have THAT much room to run an antenna, build a Rhombic and get the transmit gain as well.

This antenna allow to reduce noise on both bands. The stand alone 80m loop is approximately four feet in diameter. And made of light weight material. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable.

An FCP improves an antenna system by replacing more loss with less loss. Some have been able to erect better wires in the air because the small size of the FCP allowed better placement of the antenna. This antenna takes just 15 minutes to erect on site, can be carried by hand and is ideal for local groundwave work.

A M vertical antenna for smaller suburban sites. Notice the solder blob on the aluminium electrode. The coil was some sort of heat exchanger I recovered from the Engineering dumpster and have repurposed to serve as a coil. It started life as a coil, it is just more "coilly". The industrial strength taps on this coil were added by me. There is no particular purpose for these tapsapart from increasing the utility of this coil for antenna loading. It was a bit useless without the taps as it would have been quite hard to find and then attach a feed point wire. The real purpose of the taps was that I had purchased a Bernzomatic Fat Boy Propylene burner so that I could learn how to braze copper and other things. This project provided a platform with which I could acquire this skill and practice it. It worked quite well and I am most impressed with the Bernzomatic Burner. Propylene does not burn as hot as MAPP. MAPP was the "poor man's acetylene". I would like the utility of acetylene, however there are some very significant cost, safety and licencing hurdles to overcome, for which I do not have the will or need. Propylene will have to do. The Bronze brazing rods sold with the Bernzomatic torch have a low enough working temperature to be used for steel and iron brazing with this propylene torch. It is a real shame that MAPP gas is no longer available. Brazing is not like soldering. If a mistake is made it must be ground away and you begin again. The reason it cannot be reflowed is that the silver which forms a eutectic in the braze is absorbed into the the copper base metal. The melting point of the the braze filler metal is now too high to reflow, thus, you only get one go to get it right. The tap elements were formed from copper pipe and held in place with copper wire for the brazing operation. This antenna is suitable for amatuer construction in a suburban situation where a larger tower is impractical. After being most generously given a Seacom Marine AM transceiver by VK3ASE, my attempts to use it were thoroughly thwarted by the simple fact that a horizontal antenna just does not get out, and a short horizontal antenna only 10 meters longs gets out even worse! Thus was born this project, the aim of which is to to construct a shortpractical vertical with an inductively loaded top hat that would be usefull for both m and also 80m. It was also meant to be the first practical application of my recent discovery of soldering to aluminium and aluminium brazing. The antenna had to be "self erecting", be self supporting with only minimal guying, be as inconspicuous as possible and also survive being passed of as a flagpole! The weight of this meant it could only be raised by a team and would require very secure guying in order to not be a hazard. The 6 meter combined length of the aluminium tube means that I can safely erect this pole without assistance. I can lift the entire assembly with one hand! There is nothing new in this design, it is all by the book.

160m Antenna – Inverted L


I've modified the Front End of my old ANC-4 adding a tuned resonant circuit at the Input of Noise Channel low impedance Input to resonant circuit, next High impedance paralell resonance circuit using ferrite core and RX tuning capacitor I can cover in 4 sub-bands from 1. Thanks to selective resonance circuit at the Input of Noise antenna I can avoid intermodulation products when propagation is in a great shape birdies appeard every 5kHz or every 10kHz. According to local noises in my location a 5 floor block of flats, 19 neighbours in that house and about neighbours in metres circle around my location I can say today that my modified ANC-4 is an exellant tool to fight with local noises". With the new antenna I was able to hold a CQ frequency for lengthy periods and many stations called me. This has never happened before. This never happened before. In addition, several times I heard local hams who run high power approx. I would call as well and every time I was also able to make the contact. My conclusion is that my new meter antenna is working very well. New Meter Transmitting Antenna I have always enjoyed operating on meters. I built my first homebrew meter transmitter in with parts from a discarded TV set. It incorporated a pair of 's in the final putting out watts. Over the last 28 years I have tried many different meter antennas. My most recent antenna for top band was an odd shaped meter full wave length loop. 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. Using radials one needs a radius of approximatley feet and thousands of feet of wire which is not an option at my QTH. I built my FCP over one end of our home at 15 feet above the ground. The vertical wire is 61 feet and then horizontal for 64 feetwith another 51 feet of wire sloping down at 40 degrees from the end of the 64 foot length of wire for a total wire length of ft. I am fortunate to have two 90 foot trees on opposite ends of our city size lot to support wire antennas. The recommended K2AV isolation transformer has leakage inductance of approximatley 17 uH. I determined that Pf in series with the radiating element would resonate the antenna near to provide a good match to 50 ohms for my transmitter. The specifically recommended designed isolation transformer keeps common mode current from radiating from the coax feed line.

My homemade amateur radio antenna for the meter band is the result of many considerations, inner debates and tests. This Page Covers 1. The Compromises 2. The Hard Choices 3. The Drawings 4. The Results. June helped me understand what essential considerations I had to take into account. Nevertheless, the love of experimenting with antennas played a critical part in the successful outcome of this homemade antenna project. Granted, I could have considered a top "loaded" vertical, with a top coil inductance to make up for short physical height. ButI do not like verticals, "loaded" or not! Furthermore, quarter wave verticals just "bleed" too much precious RF energy in the ground system for my taste. After playing with all kinds of weird configurations, I finally settled on a dipole for its inherently balanced and higher efficiency in capturing and radiating energy. The result is a "hybrid" dipole or "ungrounded" vertical amateur radio antenna, depending on your point of view! I have never fed this antenna with more than watts. In fact, I usually work QRP. However, because the counterpoise lies on the ground, and is not buried, I would not be comfortable using this antenna with higher power. There might be high RF voltage present at the tip of the counterpoise which might be harmful to humans or animals if they come in contact with the counterpoise part of the antenna system. If you have trouble getting your antenna tuner to deal with the reactance of this antenna, you can try As you can see, this amateur radio antenna system for meters is "unorthodox", to say the least. It is the best set of compromises I have been able to come up with, after many experiments. It is definitely a keeper for me. Best wishes and 73 ".
