Hmm, what to do on a bank holiday Monday? Well, we decided to purchase the aluminium to build a 15m and 10m Yagi about 6 months ago, so it was time to make something of it. Dave M0TAZ is building a 4 element 15m Yagi, and I am building a 3 element 10m Yagi. Dave started constructing his 15m beam this week. It is a DK7ZB 28Ω feed-point 4 element Yagi, with a forward gain of ~6.4dBd. The elements are tapered with 3 different sizes of tubing and the boom is 40mm square and 5m long. All that’s needed now is the feed-point arrangement and it’s ready for testing! Still, it looks great and is very rigid. Cant wait to get it on the mast! Here are a few photos for now…
