just thinking of the very low projection Slim Jim and was wondering could one be made or is it too impractical and too precise
sudo nano /etc/pfclient-config.json
{
"tcp_address":"127.0.0.1",
"tcp_port":"30005",

}
sudo systemctl restart pfclient
Using the calculator above, the Velocity Factor should be set to 0.95 - since this is for the copper wire. the 0.83 (83%) is for coax cables with this specification...Above pic is J-Pole, Below is slim Jim. from first tests J-Pole seems to be better. Made to this data.View attachment 2878

Just to be more exact, it is an open stub J-pole or Arrow antenna. The original J-pole is a DC short antenna. The latest is less noisy and does not tend to gather the dangerous static voltage.sorry its an old post but thought i'd knock one up for testing.
Its on first floor level, at a window....
N-type with just some scrap copper wire.
