My project to build new OWL 14 el DK7ZB antennas at spring 2015
My antenna boom who is 35 x 35 mm in 6 m of the total length of 8,8 m caused problem when elemen tholder was mounted direct on the boom, so the solution was to mount them on distances of 6 mm
Boom with 6 m 35x35 mm in the middle plus 30x30 mm and 25 x25 mm before mounting of distances on element holders
Picture belows are before adjustment of element holders with distances
