Best 40 meter dx antenna


DC is injected into the coax to switch directions. The Yagi antenna and the helical antenna belong to the first category; the dielectric rod antenna and the Beverage antenna belong to the second. The BOG- is one of the Beverage antenna modifications. We do not sell beverage antenna Designed by Dr. The termination is around Ohms for a wire and can approach Ohms for Slinkys. They work great on 40 meters but after installing the beverage antennas I realized there were lots of signals I wasn't hearing.

Seems that I never had a real antenna for 80 or Quick View. CB Antennas As an example, a vertical antenna can be a great radiator on and 80 meters, but it may also be a very noisy receiving antenna.

That was never happening at this location. Retiring the old garden hose reel and replace it with a new one. Connect the antenna analyzer at the Beverage feedpoint through a good matching transformer.

It's up to the designer to select the best design for the job at hand and to utilize that design in the most efficient way. A beverage antenna can have very strong lobes near the two ends of the antenna and receive very poorly off the sides. I have wire doublet antennas at about 75 feet. Thankfully I had almost everything I needed. For a receive-only SW antenna 75 ohm RG-6 quad shield from Home Depot works great for high-Z antenna inputs found on portables and no baluns are necessary.

For military transmitting Beverage Antennas the height may be from 0. Homebuilding of a low cost 28 MHz yagi using parts from ordinary TV antennas. Beverage, the inventor of the Beverage antenna.Four versions of this antenna are presented: m inverted L 2. CQ m Contest January Having a R vertical for m since 2 months on top of the roof of our new house was not really the right antenna set-up for the upcoming CQm-CW-Contest !

I was looking for an inconspicuous people usually do not like to live next to big antennas and easy to build antenna for the topband. I remembered having in this contest in more than DX QSOs with an inverted L antenna, but the year before only 14 QSOs to stations outside of Europe using a full size m dipole at 18 m and operating with exactly the same radio equipment and power. So an inverted L should be the right choice for now. In 25 m distance to the house there is a 15 m high oak tree.

I Fig. The radiator is quarter wave, i. How to get an antenna on top of a tree without climbing? But how to get the other end of the wire on top of the oak tree? With a bow-and-arrow or a fishing rod? I tried a slingshot which is used by fishermen to catapult the fish food into the water.

And this works surprisingly well! You can buy everything you need to get the antenna up in the tree in a fisher shop: Leaden sinker of about 20 g weight, fishing line and the slingshot. The sinker is connected to the fishing line and catapulted with the slingshot over the tree. Then a black 1. The other end of the rope is not fixed. There is just a 2 kg steel tube at the end which can move up and. If you do not allow this movement the rope or antenna wire will break in high winds. DX-Wire can easily cope with the legal watts output power.

This will warm up the thin wire a little bid, but does no cause any problems. The black-coated type of this wire is the least visible of all. It only gets more visible from time to time during winter, when ice is building on the wire. The top loading is done by the horizontal part of the wire. Such an antenna should have many radials to work properly. In this m contest sprinter turbo failure I was using just 3 radials, each about 25 m long.

The antenna was fed with 50 Ohm coax, the inner conductor connected to the inverted L wire, the coax screen connected to the radials. This antenna was easy to match because impedance was near to 50 Ohm providing a perfect SWR at resonance frequency.

It is important to use a good insulator at the end of the wire. I first connected the wire directly to the rope. Using a watts amplifier the rope melted and the wire fell to the ground! I am using now small Plexiglas insulators without any problems.

But most important: How did the antenna perform in the contest? Much better than I expected!I see new hams asking all the time, "What's the best antenna for HF? Others are thinking of a three element beam that's being sold on-line, or the so-called "Wondertenna Deluxe" they've heard so much about.

These new hams are dazzled by the claims of the manufacturers and purveyors of these antennas, which are claimed to be the greatest thing since sliced bread, useable on all bands from meters to 2 meters, and great for both DX and NVIS. Many of these new hams seem to think, "Well, I just bought my rig I'd better buy my antenna, too! Don't do it! Just say no! It is the very, very best antenna for a new ham--and for many old-timers, too.

You've probably even heard about it before, either in QST or eHam or from your friends, but it bears repeating. This antenna is A wonderful first antenna is a coax-fed 40 meter inverted vee. If you were to feel really adventurous, you could feed the 40 meter inverted vee with ladder line and, using a tuner, use it on meters. But I digress.

For the sake of simplicity, and because most new hams are most comfortable using coax as a feedline, this short article will describe a 40 meter wave inverted vee dipole.

The Best First Antenna, Hands Down

The feedline is coax. Why should you roll your own antenna? There are many reasons, but the best reason is that it's far more fun to make a contact on your own homebrew antenna.

Fumbling around for what to talk about after you exchange signal reports? Wow the other operator by telling him or her about your homebrew inverted vee! Are today's propagation conditions less than ideal?

Don't sweat it--I'm convinced that any signal is at least one S-unit better when you're using your own wire antenna! Other good reasons for building your own are: it's cheap; it's a wonderful learning experience; it will inspire you to learn more about the technical aspects of our hobby and go on to build even more wire antennas; the components are re-useable; the components are easy to find; and you will feel the pride that stems from doing something so true to our amateur heritage.

There is absolutely nothing new about what I'm saying here. My Elmer told me to build my first antenna when I was a Novice in the early s. His Elmer told him. I heartily recommend you read it! There are similar articles on eHam now and then.

You can use 14 gauge wire but anything from 12 ga to 18 ga is common from a ham store, from thewireman.

It can be insulated or uninsulated, solid or stranded. I usually prefer 14 ga, stranded, and insulated--but you can use whatever is on hand. If the length of your coax is less than feet and you're running no more than watts on HF, RG-8X is the way to go. If you're running more power than that, or really want to minimize power loss at the higher frequencies, then use a better quality coax, such as RG RG is thicker, heavier, more expensive, and less flexible, but is generally preferable, in my opinion, from meters.

There are plenty of "how-to" guides on building your first dipole on-line. I recommend installing your new dipole as an inverted vee. The center support could be a tree branch, a flagpole, or a wooden or fiberglass pole. The wave legs of your inverted vee should each have an end insulator on them, and then some nylon, dacron or other guy rope leading out to a handy attachment point. That attachment point could be your fence post, a tree, or a tent stake shoved into your lawn.

In this way, you only need one tall support, which is the center of your inverted vee. The center of your inverted vee won't sag when you attach your feedline, as would a horizontal dipole supported only at the ends.DX Commander: The most economical multi-band antennas available in kit form with many happy customers.

Brand New. This is post in a continuing series of simple ham radio antennas. Plate 1. Dipole Antenna. You can pick your resonant frequency on each of the 5 elements. Here, the radiation pattern has main lobe, side lobes and back lobe.

The height is limited only by the nearest tall tree and the cost of the antenna is minimal. Dipole Antennas: Dual band in 2. Conventional cross dipole antennas exhibit nulls in their antenna patterns, which can cause antennas to deviate from a standard or specification.

A variety of models are available including 80, 40 20, 15 and 10 meters, or 40, 20, 15 and 10 meters, a 20, … Fan dipole. The larger the wire, the wider the bandwidth. I have trees. Two meter whips were almost three S-units about 18 dB below a half-wave meter dipole no wonder, since a meter half wave dipole is feet compared to the 16 feet of the two whips.

A fan diploe is just a name for several diploes fed with a single run of coax. I normally run a commercial "fan" dipole which Alpha-Delta refers to as a "parallel" dipole for 80, 40, 20, 15, and 10 meters.
