I got it up just in time. Should make 6 a lot better for me when the band opens. Loop fed 4 element array, this video i put it together and checked out the tune. This weekend i should be able to make a lot of contacts and some video.
5 element, reflector, driven element, 3 directors... that is your pic on the video... might want to correct that with the 4 element pic
This is a 4 element LFA, the driven element is a closed loop and is considered to be 1 element. 1 reflector, 1 driven element, 2 directors
Huh?? Guys, as shown, this is a 5 element Yagi-Uda . The driven element is commonly called a FOLDED DIPOLE. There are --3-- directors. The close-spaced director serves two functions: 1) some directivity; 2) impedance matching. The video actually shows the 4 element version: why the confusion introduced by the OP?? The folded dipole driven is used to increase the bandwidth, which can be substantial: up to rougly 25%. However, the GAIN is optimized over just a few percent of bandwidth. People use these types of Yagi-Uda's on 6m because there is an exponentially growing trend to be able to use CW, SSB, and JT-65. While you only need a regular Yagi-Uda to do this, people like the overkill of a much wider bandwidth. 73 Chip W1YW
I cant speak about this specific design, but other commercial offerings have no matching system, because the impedance is brought down to 50 ohms by the positioning of the clossst director, and to a lesser degree, the reflector.
I usd a generic pic. I will correct it if i can, please don't be alarmed, it is an error in picture on my part.. SORRY!!
Not sure how i can change the picture i posted on this post. But it is a 4 element, just added a wrong generic pic of the 5 element by mistake..
GN, Eric. Nice antenna. IMHO, your current balun has too many turns, and also, they must not be scrambled. Also, use very short connections as possible between balun's output and the active element. I see they are somewhat long. I have a simple dipole, with a 4 turns current balun, same diameter (15 cm); I'll try to upload a photo or two.... Regards - Guillermo - LU5WE.
Thanks for the advice. I went by the manual 12 turns at a 6 inch diameter. Should i use less? What will the advantage be of taking it down and redoing the balun?
