It was frotzel 10 years old when I bought it and it replaced the Cushcraft A3S. Remove oxidation, dirt and apply silicone grease as a protection to. Momentary more power is possible, but if they are oxidized or contaminated by insects, arcing may occur. Vorbehaltlich gesetzlicher oder vertraglicher Erlaubnisse, verarbeiten oder lassen wir die Daten in einem Drittland nur beim Vorliegen der besonderen Voraussetzungen der Art.
My proposal fix not tried is to add two extra screws at degree each to the other so to distribute the stress along the circumference insulator”. The contact is apparently sufficient for the current through 15 m coil for the 20 m bandbut insufficient as parallel circuit trap for the 15 m band.
The wire becomes flatter if you do the cleaning regularly. Top left shows what happens when the old model balun is overloaded with fritezl much power or if a FD3 is used for 80 m and a FB4 used for m. With back and forth motion frotzel crystals works as sandpaper so firtzel may manage it usually.
Hierbei verarbeiten wir, bzw. Here the director trap is the same as the FB and FB radiator trap. Other fditzel on the internet don’t advise cleaning with metal sponges because residual fibers would cause a short circuit. Took me some 4 weeks to clean all aluminum and traps inside too.
Der Beam ist von Further in this article describes how with a dipper the dismantled trap is measured. Gehe zu Seite 12. Can hear things like never before. It is a matter of good finishing by degreasing, for example with Dreft detergent and then rinsing with warm water and drying with a hair dryer.
The FB33 has got a much larger bandwidth and even after 10 years this beam works without any problem. The arrays are built extremely well and perform nicely. FB33 Direktor ist nicht beschrieben, sorry 73 Peter.
Because weather the grey colour of the caps become almost white. I used it on quads overe there and it was wonderful. StrahlerReflektorAbstandalles mm ich habe keine 7,80 hier in den Unterlagen. Die Abmessungen der verschiedenen Fv sind hier zu finden: The Fritzel company is good to deal with and have many other fine antenna products fritzfl as verticals, wire antennas, baluns, and a really wonderful antenna wire which is multistranded flexible Cu wire with a nice flexible critzel resistant PVC coating.
I have had 4 other HF yagi’s from 3 different brands before, but this is tops in build quality. Never mind about the floppy balun. For an antenna which has been in operation for close to 30 years, the wear and tear is negligible; proof of good workmanship.

The production of antennas by Mr. By regular “polishing” the surface becomes smoother and oxidation has less chance to penetrate the elements. In Frltzel specified his antennas and traps for an PA input! Aber vielleicht hat ja noch einer hier die vom FB33!? Es sind 18 Seiten, aber alle brauchst Du nicht. Drilling of the rivet and replaced by screw or bolt with nut is than the only cure.
frutzel Many hams sometimes neglect the maintenance of an antenna, but it is essential for your antenna system. Damage due to a dirty vintage trap and power exceeding. With two screws the interior may be removed. When the antenna is remounted you’re not the first to discover that the SWR is poor due to a wrong installed trap.
Apart from the permanent ffritzel caused to the hot toroid, the shell partially melted and changed shape. Ich sende auch gern weitere Kopien aus meiner alten Montageanleitung zu! The power was also limited to W PA input.

The windings with Teflon insulation remained intact. By measuring the resonance it is part of the total capacitance.
Till then I was quite happy with the beam. Assembling is much easier, because the holes are drilled and everything is fixed with screws. If you have any questions, problems, or suggestions about Reviews, please email your Reviews Manager.
Auch fh Daten der Trabs kenne ich nicht usw The previous owner blew a few running 1 KW. The thickest aluminium rod in the fritzdl model has a diameter of 28 mm. Abstand Reflektor-Strahler 2,90m und Strahler-Direktor 1,90m. In principle, a trap is a capacitance in parallel with a coil. The black plastic caps will somethimes crack or split and a replacement are not easy to find.
