For broadcast stations, field strength measurements must be made at known locations around the antenna system. These measurements should be made on a regular interval with a calibrated antenna. Measurements must be made of the stations fundamental frequency as well as the side lobes and harmonics to meet the spectrum mask required by the regulatory body.
Formulas and Calculations
Here is a calculation tool to help determining the actual field strength or power density at a given distance.
Application Note
In order to help better identify signals of interest from ambient signals that might already be in the area, we have included a table of VHF, UHF, and FM frequencies, as a companion to our TDS-536 TV Dipole set, specifically designed for testing at these frequencies.
Application Note
Here is a listing of the letter designations that are assigned to the frequency bands for the radio spectrum up to 300 GHz
Application Note
Our tunable dipole antennas have a set of telescoping elements that needs to be adjusted to the frequency of interest. Here is a lookup table of our Tuned Dipole Antennas and the appropriate element lengths for each balun.

Here is a handy page to convert units from dBm to to Volts to Watts based on a 50 ohm system.
Formulas and Calculations
Here is a little handy calculator that can calulate the wavelength of a frequency or frequency of a wavelength in several different units. This calculator is useful for calculating the requred antenna element length of a dipole or rod antenna for the frequency of interest.
