Wireless Yagi is ideally suited for directional and multipoint 2.4 MHz band applications. WiFi Yagi antenna is the most popular type of directional antenna in use today. The 15dBi 2.4Ghz Outdoor Yagi Antenna offers 25 deg Vertical and 30 deg Horizontal Beamwidth. It is only 25' long. This WiFi Antenna comes with an N-Female pigtail connector.

Use this calculator to walk through all the factors that make up your Total Power Output. The Total Power Output is the the total power being output from your wireless system and is the sum of:

Radio Transmit Power
-Less - cables and connectors losses
Antenna gain

Enter one parameter in each column (or leave blank) depending on what you know and the calculator will supply the appropriate conversions automatically. Up to 2 decimal places may be entered as 0.xx or .xx.

Note: Connector loss is generally small UNLESS you've got lots of 'em in which case you are probably in trouble anyway, or your cable is VERY short. Just leave the line blank if you are feeling lazy.

Loss of power over distance (assuming no FRESNEL Effect and nothing in the way). This a very idealised calculation and in practice everything interferes with the signal but it will give you a reasonable approximation of the actual loss over distance.

Enter the system Frequency in MHz and the distance in either Kilometers (Km) or Miles below and then click the 'Calculate' button. 1 GHz = 1000 MHz e.g. 2400 = 2.4 GHz.

Fresnel Zones

Defines how much clearance you need (yes you need more than simple Line-of-Sight) and for longer links > 3 Km (2 miles) whether you may have a ground clearance problem from our friendly planet. For more info on M. Fresnel and his theories go here.

Enter the Total link distance (in Miles or Kilometers), if you do not enter an Obstacle distance (in Miles or Kilometers) the calculator will use the mid-point for all calculations (Note: assumes antennas at same height). Finally enter the system Frequency in MHz and then click the 'Calculate' button. 1 GHz = 1000 MHz e.g. 2400 = 2.4 GHz.

The calculator will generate the radius of the 1st Fresnel zone only (at the obstable point or the mid-point), the 60% (no obstacle) radius and the height of the earth curvature at the mid-point of the Total link distance.

This calculator will give you one of three answers:

If you leave distance blank it will apply the defined SAD factor (or default to 30%) to the Operating Margin and supply the max. distance (in Km and Miles) at which the Margin operates.
If you enter the distance it will calculate the Operating Margin and the SAD factor.
If you enter distance but leave RX or TX antenna gain (or both) blank it will apply the chosen SAD factor (or default it to 30% if none supplied) and generate the required antenna power. If both are left blank it will calculate a symmetrical antenna gain.

To RESET any parameter above just set to BLANK before clicking 'Calculate'

Notes: RX Sensitivity is ALWAYS expressed as a negative dBm (- dBm) and is the lowest power of signal your radio can handle. Its buried somewhere in your radio spec and will be typically in the range of -80 to -110 dBm. Don't guess or 'fudge' this number.

milliWatts to dBm (and vice versa)

Power in milliWatts to dBm (and vice versa) . Enter the 'Transmit Power' (A or G above) in milliWatts OR the 'Power Ratio' in dBm and click the appropriate 'Calculate' button. 1 Watt = 1000 milliWatts.

There have been minor fixes to improve reliability in different machines and better program flow. No changes were made to the essential algorithms apart from the additions needed to cater for alternate boom and element material shapes. If you run Vista I recommend you run it as Administrator.YC now produces .maa files for MMANA-GAL optimiser.

Features of the free but copyrighted program include: calculation of the element length and element spacings of a yagi for a particular frequency, different size materials for boom and elements are catered for as are different methods of mounting, dimensions of baluns are calculated, there is provision for entering the dimensions of an existing DL6WU antenna for optimisation through an external program or to gather information on its gain, beamwidth etc. A handy SWR calculator and feedline loss calculator are included as part of the package. Stacking information is also provided as are estimates of gain. A helpfile is included that covers many aspects of yagi design as well as helping with the operation of the program.

Note: where countries use a comma for decimals you may need to change your country code otherwise MMANA files will not run. Here’s one solution: http://www.copsmodels.com/gpcommapnt.htm
