Rybakov HF verticals

These are end-fed antennas for HF usually. Commercial versions are available. 

Some years ago I bought one from SRC in Wales. Although I believe this is no longer available, they all have one thing in common: the end of the antenna is a high impedance, so a transformer is needed to get the SWR into the range of auto ATUs found on modern rigs. Usually this is an UNUN built into the antenna.

In getting things together for my free PDF book, I realised this was absent from my website! This is now corrected. As mine had been unused in the back of the garage, I swapped mine for an active RX antenna that works well. The swap was with Jason M0NYW.
