Hi there, I have finally deployed the Medium Wave Circle-design 200 metre Beverage antenna (schematic diagram above) at the woods I use in Oxford, UK. It was terminated at the ‘front end’ with a 650 Ohm resistor into a 1 metre-long, permanent copper earthing rod that I had previously driven into the ground, away from the route taken by the general public. The actual wire was orientated in a generally westerly direction, and thus nulling signals propagating from the east. At the receiver end, I utillised my self-built transformer, wound for a 50 Ohm input impedance (14 turns on the primary), thus making the entire set-up suitable for the Elad FDM DUO. It was quite a pain to set up, taking over an hour to deploy the wire and connect\u00a0both earthing rods and the transformer! However,\u00a0intial results are very promising and here I am very pleased to share 3 reception videos with you:<\/p>\n
