Wire Antenna Calculator
/Henry Garretson (W6SX) has made available a wire antenna calculator he produced to help his local DX Club - The Central Californian DX Club.
The online calculator can be used for popular wire antennas, from the standard easy to build flat-top dipole, to the inverted V dipole, but also the Quad Loop, and the equilateral delta loop antenna
