Multiband HF Projekten - Dipool Antenne's

"Buddipole" - A Portable Dipole Antenna Design by W3FF
This site is for those hams who are seeking a high performance homebrew antenna for hf portable use. Because I wanted to ... communicate on HF, I designed a portable dipole antenna out of easily-found and low-cost materials.

The title may seem to be a contradiction but I assure you it's not. The design was spurred from wanting to operate as many bands as possible while keeping the number of antennas to a minimum, ...

After assembled a two element Quad, Mario (ik7zcq) needed an antenna for 17 and 20, so he asked me to build a 17/20 dipole; I hote rotary dipoles and traps..but why don't try it!

Klik voor vergrotingA Small Garden Antenna by G4KIH
This antenna was described by Bill, G4KIH in Sprat 52 and is actually a G5RV modified to fit into a small space. Although a compromise, it performs well. Spacers made from glass fibre sheet cut into strips was used, ...

Despite the space limitations of a suburban block I wanted an antenna that would be suitable for all the HF amateur bands, including the so called WARC bands and ideally including the 160 metre band. The antenna system should also be useful for other HF services i.e. broadcast, military etc.

Improved All Band HF Doublet was constructed and refined from the experience from my previous All Band HF Doublet for use with a Z-Match Antenna Matching Unit.

Klik voor vergrotingAnother Antenna Idea by G3YCC
It's a dipole set up whereby three (or more!) parallel dipoles are fed from one coax. The one I am using at the moment is for 14, 18 and 21 Mhz, but you can choose your own bands.

The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers.

The DIPOLE antenna is perhaps the simplest and easiest antenna to erect, but I have still seen installations where basic mistakes have been made. So here is some reference data, pointers and ideas that may help you.

THE G5RV ANTENNA, with its special feeder arrangement, is a multiband centre-fed antenna capable of very efficient operation on all hf bands from 3.5 to 28mhz, ...

Klik voor vergrotingHomemade Carolina Windom antenna by MŘUKD
Here is my home HF antenna. It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m.

Traditional Definition of the Maypole: A tall pole with long ribbons (= narrow strips of cloth) fixed to the top of it, the ends of which people hold as people dance around the pole on the first of May.

I worked on 20m with one of these antennas, ... Worked well over 1,000 station in about 60 countries (1988). With only 4 W.atts! I had no baluns, no vfo.. (only 1 xtal) But I think this dipole perform better than a simple dipole.

Klik voor vergrotingSpiral Dipole Antennas by KN9B
I have always been looking for a better performing HF antenna that would comply with my no antenna CC&R restrictions in my retirement community of single story homes on small size lots. This simply means my antenna solution must be invisible or not look like an antenna.

Klik voor vergrotingThe "SRI" Multiband Fan Dipole by N4UJW
Based on research done by the Stanford Research Institute (SRI) to construct a three-frequency multi-band dipole that would work without any need for cut and try techniques, we pass on this information in the hope that it will help you more easily get this type of antenna on the air quicker.

Klik voor vergrotingThe Fence Fan Dipole by W6HDG
The multiband fan dipole has always been a popular antenna choice for getting on several bands with a single feedline and without the need for an antenna tuner. The height is limited only by the nearest tall tree and the cost of the antenna is minimal.

I did not model this with any antenna modeling software. I did it the old fashioned way. With formula's, cut and prune, a cooler full of cold drinks and some friends to help pull that heavy antenna up in the air.

Klik voor vergrotingThe KL3JM Modified "SRI" Multiband Fan Dipole by KL3JM
I built my SRI dipole for three bands, 80, 40 and 20 and designed it to be as light as possible since there would be no center support, just hanging between two trees.

The antenna was named for W4JRW who invented it and holds a patent on the basic principle and uses quarter wave stubs, which act as insulators at the frequency for which they are cut.

The Monoband HF Dipole Antenna by WB8IMY
If you're looking for an easy antenna for your favorite HF band, you can't go wrong with a halfwavelength dipole!all you need are three insulators (one is used as your center connector) and some wire.

Deze antenne is 50% korter dan de gestrekte uitvoering terwijl de draadlengte het zelfde is.
Het rendement is bijna gelijk aan de gestrekte uitvoering en met een spanlengte van 20m is deze antenne voor de 80 tot rn met 10m te gebruiken.
