New Program : LINELEN.exe

This program calculates dipole feedpoint impedance, transmission line
input impedance, and balun input impedance, versus frequency.

Dipole and line can be of any length. Line Zo can be of any
impedance.

Power lost in antenna and line is calculated. Also overall loss.

In addition to its educational value, this program will assist users
to change line length when the impedance presented to the tuner is
beyond its capability to transform it to a resistive 50 ohms.

Download self-contained program LINELEN, file size = 53 K-bytes, from
website below.

For the Wireman's ladderline # 551, where would I find the line loss
at 10 mhz in db per 100 feet (and why feet, when the other parameters
are in meters?)?
