Mystery Green Antenna

A mystery indeed.
There isn't any information on this antenna that I can find anywhere on the internet, hence I'm naming this antenna "The Green Stick".

Very interesting results, not what I expected at all.
5mhz to 70mhz
Click the images to enlarge.

As you can see the SWR is below 3 from just past 60m to 6 meters and is useable without an atu!
After the first test I was willing to sacrifice another antenna to try this one out for a while.

After self the trusty amalgamating tape I raised this antenna so the base is at about 15 foot from the ground.
Here are the results 5mhz (60 meters) to 30mhz (just above 10m)

This is the plot after I attached an earth stake to the grounding point of the antenna.

So far its a performer, I've had QSO's on 40m, 20m, 17m, 15m, 12m, 10m and i'm just waiting for 6m activity to tick that one off.

The performance soon drops off though below 5.5mhz but its still very SWL useable on the lower broadcast bands.

More information to follow, its only been up in the air less than 24hrs

All the best.
