Antenna Theory:

There are many textbooks telling that an antenna
to be effcient needs "much wire in the air".
Now the time has come to correct this view.

What textbooks say that? EZNEC says that a 3 meter
tall monopole has a maximum gain of 1.5 dBi on 160m
while a 38 meter 1/4WL monopole has a maximum gain
of 1.36 dBi. In other words, they radiate approximately
equally well both with high radiation efficiencies.

The problem is not with the antenna's ability to
radiate. The problem is in getting the RF energy
into the antenna.

The problem is not with losses in the antenna. The
problem is finding an efficient j2250 inductor for
the matching network.

If we knew what your matching network looks like, we
could estimate its efficiency.
