Antenna Downtilt and Coverage Calculator Pasternack

Pasternack

The Antenna Downtilt and Coverage Calculator (aka Antenna Tilt Angle Calculator) is used to determine the approximate downward angle, measured in degrees, which the transmitting antenna is to be positioned for optimal signal strength and coverage. It also provides, given a beamwidth, the inner and outer radii of beam's coverage.

Pasternack's EIRP Calculator determines the radiated power given the transmitter power, the cable loss to the antenna and the gain of the antenna.

Helical Antenna Design Calculator 

Daycounter, Inc.

Helical antennas, invented by John Kraus, give a circular polarized wave. They are one of the easiest to design. Find a tube with a circumference equal to one wavelength, and wrap wire in a helix spaced a quarter wavelength. The conductor width is not of great importance in the design. The greater the number of turns the greater the directivity or antenna gain. Receiving and transmitting antennas must be wound in the same direction, since the wave is polarized.

Whip Antenna Design Calculator

Daycounter, Inc.

A whip antenna also known as a monopole antenna looks capacitive if it is shorter than a quarter wavelength, and is tuned to resonance with a series inductor. PCB antennas are often shorter than a quarter wavelength due to board size restrictions and often fit into this category.
