Positive Propagation antennas are handcrafted here in the USA, using as many US manufactured materials as we can. All of the major components are sources from the USA.
3d filament from Atomic and MatterHackers
Toroids from Fair-Rite Products
Wire from Davis RF
Rope from Synthetic Textiles
With a wire length of about 42 feet and a 9:1 transformer this antenna is a go anywhere special. Of course other lengths can be used but make sure it is not a multiple of the bands you would like to use.
The 9:1 design has been around for ages and has been proven time and time again. I have taken that design and made an all in one solution for portable amateur radio operating.
We are currently selling these antennas from our ebay store click the link below.
