Hentenna for the 6m band

Hints & Experiences

The feeding section perfectly fits into a small (13x13mm²) 1m long cable channel. The cable channel suffers from a couple of holes drilled in it's sidewall in order to guide out the feeding leads. A luster terminal is finally applied to connect the coax cable. In a former version a bamboo pole was used; doesn't look as nice, but less work to be done...

You might practice some inventiveness in order to connect the 1mm cables to the end of the aluminium poles... I squeezed the end of the pole a little bit with pliers and cut a 4mm thread into the inner surface of the Al pipe.

Used it as shown above. The aerial gave nice instantanious results (beacons & Co.), even though that the band was pretty dead, I managed to have some QSOs with reasonable results. My impression is, that the Hentenna performs better than my commercial Al-pipe dipole. Moreover it is easier to transport and/or store anyway.
The total costs were about €10.- w/o the feeding RG58 --- I known, 50Ohm cable to a 75Ohms aerial...
