Multiband HF Projekten - Dipool Antenne's

Klik voor vergrotingDipole Antennas by SMŘVPO
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.

Klik voor vergrotingA 2-band 'No-Trap' Trapped Dipole For Small Gardens by ZS5MGD
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, ...

"Are you going to use this for fishing or ham radio?" asked the sporting goods salesman. "I'm a fisherman," I said, "but this is for ham radio." "Well," he said, "I've sold lots of these, and I haven't sold one yet for fishing."

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.

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, ...

"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.

Klik voor vergrotingThe Cloud Warmer NVIS Beam
Some of you may recognize this design as nothing more than a half wave dipole, but upon closer examination, you will see that there is a reflector at the bottom of the antenna spaced at about .15 wavelength or less from the driven, (dipole), element.

Klik voor vergrotingThe Double Bazooka Antenna
The Double Bazooka Dipole is a very efficient single band antenna which is very quiet, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends.

Klik voor vergrotingRibbon Dipole by 4S7NR
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 $4 Special by W1GFH
Sure, you can find "all-band wire antennas" for sale in the back pages of Ham magazines costing $150 or more. But beware: Marconi spins in his grave everytime a ham buys an aerial instead of building it.

Klik voor vergrotingThe Lattin 5 Band Antenna by W4JRW
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.

Klik voor vergrotingWindom Antenna by JA7KPI
I'm using homebrew Windom-Antenna recently. In the total length of this antenna is 41m, height is about 11m, and diameter of element is 2mm. However, it is up only about 4m height from a metallic roof.

Klik voor vergrotingZig Zag Antenne Project door PE1KQP
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.
