Note
I.G.: Below you can see SWR (at 350 Ohm Terminal) for 88 Feet Dipole Antenna placed at 10 and
20 meters above real (simulated by MMANA) ground. As you can
see the 88 feet antenna really has at the amateur bands SWR/Impedance
that could be matched with simple ATU.

As you can see, the 88 Feet Dipole Antenna is much better matched with
350 Ohm feed line in compare to 44Feet Dipole Antenna. It is
only proved the old amateur’s wisdom on antenna the bigger the
better.
On my look the 88Feet Antenna is more preferable, but room for this one!

Now
, using the standard accepted formula for calculating the ¨approximate¨ length of a wire
dipole for the HF frequency range
from about 5 to 25 megaHertz.... 143 / frequency in megahertz let us play with a little math amigo !!!

143/
7.15 for the half wave resonance on the 40 meters band will yield exactly 20 meters , so 10
meters on each side or
moving to Imperial British Measures 65.6 feet overall
or 32.8 feet on each leg. (Figure 3 shows the 66 Feet Dipole Antenna.)
