RaDAR – The awesome end fed

In my minimalistic RaDAR kit, I carry a 40m half wave end fed antenna and manual tuner / coupler / impedance matcher – it’s actually all that, as simple as that. A parallel tuned circuit made of a few turns of enamelled wire wound around a tiny red coloured TO50-2 toroid and a varicap. Lightweight and the size of a matchbox, and it’s a matchbox!

I found some images I’d saved from the Internet a while back which are really excellent in showing the versatility of the end fed!

Many thanks to KC8AON for the these images!
