Performance

There are several main parameters of Yagi electrical and mechanical performance which determine the effectiveness of your antenna.

JK Antennas provides this information on all of our products - you should know what you are buying, and we have done our best to provide all of these data points. If you have questions, please don't hesitate to ask us.

Forward Gain -

The concentration of energy in the direction you want emphasized. Gain should be maintained over an entire range of frequencies, and must be stated in comparison to a standard reference.


Unlike many other antenna manufacturers, we report  Gain (dBd) over a dipole in free space (dipole - 2.14 dBi)

 

Response Patterns -

The pattern of a directive antenna changes over a frequency band and is measured in two ways:

 

• Front-to-Back Ratio (F/B) - This is the ratio of the response in the direction of maximum gain compared to the response directly behind the antenna (at 180⁰)

• Front-to-Rear Ratio (F/R) - This is the ratio of the response in the direction of maximum gain compared to any response in the hemisphere behind the antenna (from 90⁰ to 270⁰)

• Standing Wave Ratios (SWR) -  An efficiency measure showing the relative size of reflections and their impact on the power of the antenna.


All of our antennas boast low SWR, across the antenna's operating band.

 

Mechanical Strength -

Impressive electrical performance means nothing if you have an antenna with poor mechanical design. Our antennas are designed to withstand high wind speeds and can be ordered with optional trussing kits if heavy icing is a concern for the larger sized Yagi elements especially on 40M and 80M.
