Whip Antenna Design Calculator
A whip antenna also known as a monopole antenna looks capacitive if it is shorter than a quarter wavelength, and are tuned to resonance with a series inductor
Dipole and Inverted Vee Antenna Calculator
The basic formula for determining the wire length of a center fed, 1/2 wave wire dipole or inverted vee antenna - 30 mhz or less is 468/freq-in-mhz for feet and inches or 143/freq-in-mhz for meters
YAGI a 3 elements
This page covers 3 element Yagi Antenna basics. It mentions Yagi Antenna Calculator and mentions formula used for calculations
How to measure the capacitance of a capacitor
For example, a 1 uF capacitor or a 25.3 mH inductor will have 159 ohms of reactance at a frequency of 1000 Hertz
