G0KSC SC0606L 6el 50Mhz Yagi Antenna with a 6.75 Metre Length Boom

This antenna is not recommended for use in noisy city locations due to the elevation pattern. This is not a fault with this antenna, it is a characteristic of this boom length/ Wavelength

This antenna has been redesigned and represents what I beleive to the the 'ideal boom length' for an OWA direct feed 50Ohm Yagi. This can be seen in the model in the super flat SWR, the high levels of F/B ratio along with the excellent gain and pattern.

The model below is designed with 12.7mm / 1/2 inch elements and a 12mm element version. If you require a version of this antenna with another diameter wire, Email me and I will remodel. It is NOT POSSIBLE to simply resize the elements when using a different diameter wire and get the best performance in my opinion, I remodel the whole antenna each time. Element positions also need to change for the ideal antenna to be achieved again. Please read all the way down this page, there are other versions of this antenna using tapered elements too. As I have more requests, I will remodel in other element diameters and tapers and pulbish those too.

This fantastic antenna at 15m up

An Excellent SWR to go with the fantastic pattern!

Remeber, mail me if you have different diameter tube requirements and send photos of built antenna!
