Yagi manufacturers:

This table, is a one on one copy of the data provided by the Internet sites of the different companies.
There are those who are accurate and those who probably are a bit optimistic.Overall u can get a good impression what is available at the market.
For any further information please see their websites they withheld lots of information sometimes its as detailed as the type of alluminium and the thickness of all the individual elements.
You can get a good impression of what gain is truly possible by going through the chapter beams and gain, then compare this to the given diagram there.
Good luck with your search!

R  = Remarks:

# -  HDSP, own design. Most are measured in real life and found correct. honest figures! Dimensions can be found in BEAMS.

0 -  a dipool, this antenna as described in other chapters (basic) has no FB

1 -  HB 9 CV, This is a 2 elements yagi in which both elements are Fed with that comes somewhat higher gain than a created            from a natural 2 elements.

2 -  Cross Yagi, On the boom of this antenna there are actually two identical yagi's one polarized horizontal and one vertical.             With a simple antenna switch u can make a strong local qso or get ride of that local station which keeps squeezing the mike        or go Horizontal for the DXing and loose that noise.

3-   LOG yagi, this actually means Logharitmic yagi. You can find lots of information about this antenna in chapter Beam                     antennas. Its advantedge lies in the broadness of the bandwidth.

4-   The ZX yagi has 3 reflectors..5 directors.

5-  Maco is one of the firms who do not releas to wich antenna they have compared it with so I have trouble telling what to do        with the numbers given perhaps you can deside for your self!   

6-  Wolf has got D versions in wich they have two yagi's interlaced on one boom (horizontal and vertical)        

7-  Jogunn has got many other types.( But honestly 20,95 dB from a 11 meter boom ....? another nice feature is there antennas        have  extra AUDIO gain.....(?) There are others who are a bit over done!!! but this is NOT NORMAL !

8- The Skypper antenna is based on the G4ZU wire yagi. the Director and Reflector are bend towards each other and consist of      wires instead of aluminium it is a light small (faults down to a meter). If you are looking for something small & light with gain      you might take a look.

9- The wagi is made by 1SD019 and consist of a 5 elements wire yagi...with a short boom this is a perfect DX cannon for                   expeditions its weight is around 4 kg.

10- These designs have the HB9CV principle, this means that there are two elements fed. (slight higher gain)
