What is it?

A kit based on a custom PCB board to build your QRP dipole antenna. The kit contains all you need to build your own balun (PCB, FT50-43 toroid, 100pF capacitor, BNC connector and magnet wire for the toroid).

This version also has a current balun in line with the 1:1 voltage balun, which should increase efficiency in case the dipole cannot be mounted completely symmetrically (eg. legs have different heights or ground is different).

This is a kit and needs assembly. You will need to wind the toroid with the magnet wire, solder the toroid and the BNC connector.

The kit contains: 1 PCB 1 female BNC connector 2 FT50-43 ferrite toroid (see also options) Enough magnet wire

The antenna wire mounting holes are suitable for wires up to 1.5mm diameter (with insulation). The holes can be extended with a driller for slightly thicker wires.

Why did you make it?

Working primarily QRP, often portable I wanted to have a minimal system as lightweight as possible. Often, antennas make up a considerable amount of space and weight of the overall system and I looked into ways to minimize this.

What makes it special?

It's size and simplicity. The resulting antenna is lightweight, compact and can be deployed quickly.

Impossible to assemble, impossible to reach seller

I'm disappointed. Omitting the seller's non-existent communication, the PCB and ferrite are extremely small, making it very physically challenging to assemble.

It's not a well-thought-out product, but someone's overpriced experiment in PCB design learning. I consider my money wasted, sorry.
