Following the death of my cheap fibreglass tri-band collinear, I decided to have a go at constructing a simple dual band antenna for use at home.
I was looking for something that was vertical, omnidirectional and with good gain that I could make quickly and easily. The answer came from Sean, M3FVB in the form of his excellent article on building a 8db collinear.

I was itching to get on the air with my new FT-857 so I made up a quick and dirty set of simple interface leads.
The FT-857 has a data port on the back and a digital mode that is selectable from the menu system. It also has a data port VOX function so any audio being presented on the data port will activate the TX.

I love a good Yagi. I also love folded dipoles. So why not mix the two up and make a nice Yagi driven with a folded dipole?
This 12 element monster is easy to make and produces a theoretical 12.75 dBd gain. The dimensions were calculated using this tool. The details are: Continue reading “12 Element Yagi for 70cm”
