I’ve been curious about the T2LT “flower pot” antenna for a while. It’s fed from the bottom and attached to a sturdy PVC pole. I can easily hoist it into a tree, and it has a low wind load, so it could go on top of a flag pole again.
I built it at the SPARC Elmer night from some 75-ohm TV cable I had laying around. I taped and cable-tied it to a thin bit of PVC, and I adapted the feed point from 75ohm TV cable connector to SMA. I had built it long to allow tuning, but it tested to be just about right for 146MHz when I put the VNA on it.
