YouTube - Antenna for Top Band and Eighty

A YouTube video describes the installation of an antenna at RA9FTM for the 1.8 and 3.5 MHz bands.

The antenna system was designed by RA6LBS based on the W1CF hybrid coupler. It consists of 4 switching phased vertical wire elements on 3.5 MHz and the central tube-mast is used as a vertical antenna on 1,8 MHz with a capacitor load on the top.

The YouTube description reads:

This video is from the world of Amateur radio, about low bands antenna installation on a rural position of RA9FTM radiostation.
