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.



VHF / UHF Direct Connect Beams

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



Phil Salas AD5X 40 through 6 meter HF Portable Antenna

Simplified and improved design from that published in the July 2002 QST. Now an aluminium tube design which is lighter and more compact tan the original.





Two portable 6 meters antennas by VE7CA

Both antennas were designed for easy construction and quick assembly and disassembly. The quad provides a measured gain of 4.2 dB over a dipole and the yagi 5.8 dB over a dipole. Details are given describing the methods used to measure the gain of both antennas.




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!



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.



QRP Six Metre Portable Dipole

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



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.



6 Meter J-POLE

If you're interested in Upper Sideband (USB) you will run into folks who will tell you that you should use a horizontally polarized antenna, probably a Yagi Uda beam. If you want to work FM, everyone will tell you to use a vertically polarized antenna such as a Ground Plane or a "J", since that's what the mobile stations and everyone else is running. Well, here's the low down scoop so you can have your cake and eat it too!

Use a vertical omni-directional antenna for both modes, actually all modes, and you will have the best of all possible worlds! I say this based on my own experience, as well as others who have worked a great deal of DX with vertically polarized antennas. For about 31 years now I have used vertical omnis on this band to very good success. I've worked all 50 states, and four countries, mos
t times running not more than about 100 watts of power.



5 BAND LOG PERIODIC DIPOLE ARRAY

The unique feature of the Telerana is that the elements are wire instead of aluminum tubing which makes for a light weight LPDA (log periodic dipole array). The array is suspended within a framework made of fiberglass poles emanating from a central hub with the ends tied together with light weight rope around the perimeter.



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.



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?



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).



K0FF's 6 -meter SLOOP

It presents a high angle of takeoff when mounted low, and singly (great for Es), can handle 100W. Stack two or more for extra gain if needed.

The shape is a closed 28" square, with a mounting /support bar through the middle. This mounting bar is attached to a copper TEE at the drive end, and to a CPVC TEE at the other end. The CPVC TEE acts as support and end-insulator for the radiating element and provides a mounting point for the Butterfly.

A large (3/4") part is used, and adapted down to fit the water pipe, to increase its insulating qualities, as there is very high voltage at this point. A strip of brass or copper 1/2 by 3" is screwed to the outside middle portion of the CPVC Tee, through a small center hole, and is rot
ated one way or the other as a resonance tuner (Butterfly). When the Butterfly is at right angles to the element, the frequency is the highest, when parallel, it's the lowest.

A Gamma match sets the impedance to 50 Ohms, and the Butterfly adjusts the center frequency. Center frequency is 50.00 to 50.800 with the exact dimensions shown. Typically the 2:1 SWR bandwidth exceeds 500 kHz.



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!



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.




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



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.



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.



Trap Dipole for 17, 12 and 6 Metre

Homebrew trap diplole designed and constructed by John Beaumont G3NGD



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!!!



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



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.
