In my most recent posting on this subject I said:
"...I'm puzzled by how the feed current at the base of any antenna, regardless
of its length, will always be at a maximum at its base. A half-wavelength
antenna presenting a few thousand ohms of input impedance at its base would, I
think, have difficulty accepting "maximum FEED current" there..." Perhaps it
was because the hour was late, but I completely disregarded the universal use
of matching devices at a feedpoint in order to overcome feed difficulties.
Apologies for the omission. In my case, with an inverted L antenna having a
total length of 170 feet, just a series capacitor at the base feedpoint with a
value of about 255 pF gives me an SWR of 1.15 to 1. However, that figure is
measured at the shack, about 100 feet away. Also, I transitioned the subject
matter too swiftly from feedpoint impedance to radiation resistance. The two
are different and should not be confused with each other. 73, Charles, W2SH
