Simple Dipole Antenna Guide
By NP4H Mission Control
A dipole is one of the easiest and most effective antennas in amateur radio.
The basic formula is:
Total length in feet = 468 / Frequency in MHz
For example, a 20 meter dipole around 14.2 MHz is about 33 feet total, or about 16.5 feet per side.
Install it as high and clear as possible, and always check SWR before operating.
