The calculations are all done with Javascript. You turned it off, so they do not work. php Bytes You may want to combine it with a folded Dipole or straight Dipole. Elements Diameter of parasitic Elements [mm] Diameter of Boom [mm] Is the boom isolated from parasitics? yes no. It uses the graphs and principles developed by DL6WU and printed originally in the German Radio Magazine VHF Communications March The article was titled Extremely Long Yagi Antennas. For best front to back ratio it is recommended that a yagi be constructed with one of the following numbers of elements - 10,14,19, Yagi builders are reminded that DL6WU designs are primarily for long yagis. A boom length of 2 wavelengths or 10 elements would be a minimum sized antenna. On the other hand, yagis with as few as 8 elements have used the design and worked very well.

The work of David VK3AUU AR Feb in developing some equations to fit DL6WU's graphs was very valuable. The reflector calculations are based on a Basic program written by KY4Z and W6NBI and with suggestions by DL6WU. The ARRL Antenna Handbook provided information, as did various sources on the Internet. The author acknowledges the ARRL Handbook for information on coaxial cable impedance, dielectric and velocity factor. The formula source for the impedance calculations is from "Round and Square Section Parallel Transmission Lines Theory, Practice and Applications" by Roger Harrison and Andy Sayers VK2AES, GippsTech Conference , Churchhill, Victoria, Australia.

The problem is that if you live in a country that uses a comma instead of a dot for indicating decimal numbers your machine Windows or Apple OS will output a file for MMANA using commas which will not be recognised by MMANA. The solution in the case of a Windows machine is to set your country preferences to a dot for the decimal point.

All was then fine as it was possible to adjust country settings. This was developed by Jack Dodds VE3UKD from short form code provided by me.

On-line directional antenna designer. Unlike most antenna designs on this site which are omni directional, this antenna type is very directional and has been constructed to facilitate the reception of telemetry signals from the smart falconry telemetry project. Calculate the required dimensions for a three to eleven element directional yagi antenna construction for any given frequency. Enter the required frequency in MHz and the antenna designer will calculate the dimensions of the required elements as shown below. The center frequency of the antenna in MHz. The amount of antenna elements the more elements the more inverse log gain it has and directional beam becomes more narrow. Boom diameter BD in millimeters the diameter of the PVC pipe where the antenna elements will be mounted on. Antenna elements diameter ED in millimeters the diameter of the antenna elements. The Yagi antenna is a directional antenna using parasitic director and reflector elements to amplify the radio frequency signals from the direction it is pointing.

The more parasitic director elements up to a point added will increase the DB gain and narrow the receptive beam width. It is different from the other antenna types because of this 'one direction reception'. Performs very well and can be used for RX and TX purposes. Frequency calculations are based on radio waves traveling at the speed of light meters per second. It stands to reason that more length is needed to mount these elements to the boom and you might want an area behind the reflector to mount the antenna itself. Second to note about the boom is that it is assumed to be made of non conductive material, like PVC piping. Do not use aluminium tubing or other metal materials for the boom.. To connect this to 50 Ohm transceivers we need transformers to convert 73 and Ohm to 50 Ohm. A separate section deals with connecting the driven active antenna element to a 50 Ohm transceiver via coax. This antenna design calculates a single dipole rod as active element a gamma match would be the simplest way to connect it to 50 Ohm transceivers.

Gamma matching is used for the falconry telemetry system as the single rod dipole has a narrow bandwidth which is exactly what is needed when tracking a very specific frequency. If however you are a radio amateur operator and want an antenna with more bandwidth, then a folded dipole can replace the active element of this antenna design. Antenna matching the driven element. Gamma match One of the simplest methods of matching a dipole to 50 Ohm coaxial cable. The adjustment point to get the SWR as low as possible is around 0.

The recommendation is that the matching rod is half the thickness of the dipole material, however using the same material as the dipole has minimal effect on the sweet spot.
