the sun did not shine.
it was too wet to play.
so we sat in the house
all this cold, cold, wet day.
i sat there with sally.
we sat there, we two.
and i said, 'how i wish
we had something to do!'
too wet to go out
and too cold to play ball.
so I went in the shop
and finally completed the assembly of the Discone antenna I have been putting-off for months.
If you're unfamiliar, a Discone is an omni broadband antenna - good for multi-band scanners and other applications where directional gain can be traded for wider bandwidth. I had previously purchased a Diamond D130J. It's a nice antenna, though it's slightly cumbersome to move around. I have a need for something more "mobile" and less likely to get beat-up while being mobiled.
I designed an 8-radial setup using 3D printed hubs and 3/4" tape measure as the conductive material. I have a long history with tape measures as antennas, and yes, I have put them in orbit around the planet. Here's the basic CAD model, the printed hubs, and the raw materials.
