After all the Es fun on 6m and encouragement from some of the EmE guys I decided to build a bigger yagi, I was originally going to build a 10 element but I was very sceptical about building a yagi with a 15m boom. So I opted for optimized 6 el yagi on a 7m boom. This yagi is quite cool, designed by Pop YU7EF, http://www.yu7ef.com/ef0606.htm
I used 40mm and 35mm square boom material and 10mm elements. It’s quite rugged but it will not survive the winter here in Iceland. So it can be disassembled into max 3m parts.
Feed point impedance of this yagi is 50 ohm so I only have to use a simple balun to connect the coax.
I was quite supprised that it just matched perfectly and has SWR 1.1 at 50.100
… uhm..that’s what the graph in EzNec showed..so I was supprised I could build the thing so near specification!
So, now I just wait for the moon OR Es top open up
