THE HENTENNA

The Hentenna was developed by Japanese 6 Meter Hams, JE1DEU / JH1FCZ/ JH1YST in the 1970's and can be designed and built for hf thru uhf and possibly beyond! Sizes given are for 6m.

After much experimentation, finally, the antenna was developed with good performance, however, it was difficult to explain why the performance was so good, or how it is worked basically at that time. So it was named Hentenna, "Hen" means "strange" in Japanese.

The antenna has good performance and many advantages and it has become very popular in Japan. Many JA st
ations make it and enjoy it at home or in the field. Some Japanese 6m beacon stations are using the Hentenna antenna.



The Fence Fan Dipole

A Quick, Easy and Inexpensive Multiband Antenna By W6HDG



EI7BA Multiband Cubical Quad

It covers six bands 20m to 10m on HF and also 6m. It is a Boomless (spider quad gem quad) design. It uses Glassfibre arms (a must). It uses a single coax line to a homebrew antenna switch. From there a seperate feedline goes to each of the Driven Element feedpoints. There is a homebrew Choke Balun at each feedpoint.

Performance
I have no accurate method to measure forward gain but I reckon it is the text book 6 to 7 db. F/B ratio is consistently 5 to 6 S points on my TS850 S meter on all bands 20 - 10m. I don't know how many dBs per S Point for my TS 850 but it is surely at least 3dB per S Point. So this translates to a minimum of 15 dB and arguably as high as 30dB. As wi
th all 2 element Quads It has a wide beamwidth about 60 degrees.

ADDENDUM.. An extra two bands..!
I have added three elements for 6m and 2 elements for the European 4m (70mHz) band to the existing spider, and on a seperate 6ft boom which is clamped to the spider, I have 5 elements for 2m, and 9 elements for 70cms.. A grand total of 11 bands..



6 Meter 5/8 Wave Vertical Antenna

The G3JVL 6 Meter ground plane vertical is a compact antenna that is ideal for portable operations. If needed, it can be disassembled into a very small bundle no longer than the longest element.

Although a little engineering work is required, it is well within the abilities of the home workshop and all you newly licensed amateurs or 6 Meter buffs!



VHF / UHF Direct Connect Beams

Sizing
details for several 2 to 4 element beams from 10m to 70cm



COAX FED 6 METER EXTENDED DOUBLE ZEPP ZIP CORD ANTENNA

These plans for this version of the EDZ for 6 Meters came from the previous Webmaster of the NRRL, the counterpart of the ARRL in Norway, LA2PJ, for all to enjoy and our many thanks and best wishes go out to him. This is a very inexpensive and easy antenna to build and has been used for many years in Europe by 6 Meter operators with great success!



N1RIK 6 METER MOXON

Performance:
I was checking the F/B ratio on a station about 200 miles away in South Carolina who was running about 1KW. He was S8 to 9 with me pointed on him, however an S4 with my backside to him. That's a 4 S-unit difference, and at 6 db per S-Unit, aprox. 24 db F/B ratio, which is around spec.

During normal conditions via groundwave, I can talk about 200 - 250 miles out with my antenna 20 ft. AGL.



THE KK5ID 6 METER ROTATABLE DELTA LOOP

The 6 Meter Band may be dead at times, but help bring it to life with Larry's rotatable loop project. Simple, easy to build and won't break the bank.




6 METER EDZ SIGNAL SQUIRTER

The Six Meter Extended Double Zepp is a very easy and inexpensive antenna for the 6 meter buff to build in about an hour or less and will add about 3 db to your signal from it's broadside bi-directional pattern when installed about a half wave up from the ground. You mignt call it a diplole with gain!

All of the materials used to build this antenna can be found locally or you may even have them laying around.



HOME BREW 6M HALO Mobile on "The Magic Band"

This is the Jones version of the Lawn Chair 6M Halo as viewed through the rear window of the mobile.

Ain't that just the sexiest thing you've ever seen on the outside of a vehicle?



The Super J-Pole Antenna(Collinear Design)

Javascript for calculating the lengths of tubing to be used for the construction of a Super J-Pole. The antenna I constructed was made of 1/2" tubing.



HexBeam for six meters

This is a hex beam I designed for six meters. It has three elements with a turning radius of 54 inches. This antenna can be built from low cost materials available from the local hardware store.



QRP Six Metre Portable Dipole

Simple design using a central box and two whips. Fits onto a camera tripod.



MULTIBAND ONE ELEMENT VEE BEAM BY LA0HV

The TriDouble dipole has two elements of 3/4 wavelength each.
It has resonance at the design freq but the impedance is high (500 Ohm) and the reactance/inductance value changes greatly when you change frequency.

To compensate for this you shorten the element length a bit and
add open wire, 400-600 Ohm (not critical). This will decrease impedance to 200 Ohm at the design frequency. This is why I use a 4:1 Current balun (must be a current balun).



Halo for 6 meters

A good antenna that can be used for the car as well as the house. This antenna maintains good omni-directional
horizontal polarization.



Trap Dipole for 17, 12 and 6 Metre

Homebrew trap diplole designed and constructed by John Beaumont G3NGD



2 Element Yagi for 50 Mhz

G3SYC designed this antenna in about 1990. The antenna works best between 15 and 20 feet off the ground and some
nice dx can be worked with it. Easily folded up and stored away when not in use, and has a minimal impact when
erected.



50Mhz HIGH GAIN ANTENNA AND MASTHEAD PREAMPLIFIER

Nine element long yagi on a 9.2m boom which is effective over a range of 50.0 - 51.5 Mhz and if carefully constructed and tuned then the forward gain could exceed 12dB with reference to a dipole.



6 METER OMNI HALO from KB1DIG

This halo is made with a true Gamma Section and is fashioned from aluminum. Most of the parts are leftovers from old car projects.



3 Eelement beam for 6 meters

This design uses a 6 foot boom and a gamma match feed arrangement.



YU1QT 5 ELEMENT 6 METER MOXON

Summer is for 6 meters! So YU1QT, Andra, has designed a special 5 element 6 meter moxon.
Need gain?
How about 10dbi?
The dimensions are shown below in meters.
Have fun!!!



3 Element 50MHz Yagi

Gamma matched 3 element long yagi for 6 meters. 2 meter boom length 6.1dB forward gain 25dB front to back ratio



6 Element Log Periodic Yagi for 6 meters

This yagi antenna has a very clean polar pattern and a good front to back ratio.



4 6 and 8 element Beam designs for 6 Meters

The 8 element is an absolute monster - 41 foot boom - mounted at 87 feet giving 14.0 dBi gain

  1. This web page of yours contains a link to my web page(s) describing the construction
    of a homebrew, mobile 6M HALO. Thank you for the exposure!

    But, clicking on my link results in a POST (!) out of your PHP program to fetch my
    static HTML page. This results in an http “405 Not Allowed” error at my server(s)
    (_not_ under my control) because POST is not a ‘method’ for an HTML URI.

    I am referring to
    [ HOME BREW 6M HALO Mobile on “The Magic Band” ]
    about 40% down your page.

    I should think this might occur with other HTML links referenced in your web page(s).

    Thank you and Happy New Year.

  2. Hi Jonesy,

    thanks for drawing this to my attention. I test all the links as I add them and yours used to work OK on your old server but you moved the page sometime after I set the link up and your new server sometimes (but not always I found) responds with a 405 to the post. I’ve changed the method to get now and it seems to be working consistently for your page and the existing ones I’ve tested still work.
