Oxidation created pits and bumps on the elements. Because of the lenght of the driven element which went from almost 27ft to abt 39ft for 40 mtrs I changed the element to the 30 mtr band. The FB33 has got a much larger bandwidth and even after 10 years this beam works without any problem. StrahlerReflektorAbstandalles mm ich habe keine 7,80 hier in den Unterlagen.
When the antenna is remounted you’re not the first to discover that the SWR is poor due to a wrong installed trap. In Fritzel specified his antennas and traps for an PA input! Vice versa with the longer traps as used for the 40 meter band length 45 cm I have observed which the tube aren’t round but are oval. If that process has taken a long time it may be difficult to push the trap out of the case. My more than 35 years old Fritzel antenna elements look new after a thorough maintenance. Till then I was quite happy with the beam. The rivets replaced by stainless steel bolt and nut. Elements, active in band number, 3, 3, 3. Bei den Maßabweichungen schreibt Fritzel Elementlänge ☑0mm und bei Abständen ±50mm ohne praktische Beam ist von FB FRITZEL FB Specifications, electrical, 20m-Band, 15m-Band, 10m-Band.
