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.

Cheap Yagi Antennas for VHF/UHF

These antennas are relatively small, easily constructed from common materials/tools and have surprising performance.
The feed method is greatly simplified by directly soldering the coax to the driven element. No baluns or gamma matches
are used in this design. This simplified feed uses the structure of the antenna itself for impedance matching.

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.

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..

2 meter mobile antenna

The antenna is an atypical vertical: instead of the common 1/4 wave vertical monopole or ground plane this design
employs a 3/8 wave vertical section and short radials to complete the "ground plane." Effectively, an off-center-fed
vertical dipole that does not rely on the earth to complete the bottom half of the antenna.

A Moxon Rectangle For 2 Metres

The aim of the current project is to provide a lightweight loft antenna for 2 metre SSB that can be easily rotated by a homebrew driver and controller.

The lat
e Les Moxon G6XN developed what has become known as the Moxon Rectangle from a design by Fred Caton VK2ABQ. The Moxon is basically a two element Yagi with the ends bent in towards each other with a small gap separating them. The Moxon has three main characteristics: It is small as can be seen from the MoxGen program below has incredible front to back ratio and it's feed impedance is 50 ohms. The gain is around 5 db.
