One of my interests is listening for long distance radio signals on the 88 to 108 MHz band which is otherwise known as Band 2 or as simply the FM band to the general public. I recently came across this impressive antenna array from Bernd, DL7APV in Germany.
According to DL7APV, the antenna array has an impressive gain about about 14 to 15 dBd with a beam width of about 10 degrees.
The individual antennas are the 9-element 3H-FM-9M19 - Modell 2019 from Antennenland which retail at €109 each.
Despite the fact that the antenna has 9 elements, a lot of them are used to make the antenna broadband. It seems to have the same gain as say a narrowband 4 to 5-element Yagi.
