New HB9ABX Antenna

A Wonder Antenna ?

----------------------------------------------------------------------

Dear OMs,

in several mails I received comments, that wonders

are physically not possible.

I never told that !

My new antenna, simply is a construction where all unnecessary losses

are prevented, and where the target is, to radiate most energy towards

the sky, into the space above the antenna.

Not into the building, not into the ground, not to burn

the power needless in loss resistances.

Most short antennas have high losses in copper losses,

ground resistance, separation currents, heated isolation chokes,

lossy traps, matching networks and so on.

I am told frequently, that the very low radiation resistance of

short antennas prevents a high efficiency.

This is absolutely wrong.

The efficiency of any antenna is obtained by the relation between

series radiation resistance and the series loss resistance, disregarding the

absolute value of the radiation resistance!

(If the total loss resistance would be 0, then the efficiency

would be 100 %).

If you manage to keep loss resistance to a few percents of

the radiation resistance, you reach a very high efficiency.

Observing all above mentioned points, that's the full secret.

With the best 73s
