Only bought some new stainless bolts etc. By measuring the resonance it is part of the total capacitance.
The traps are made with soft aluminium wire. Even dirt will not stick easily on the outside. That has never happened during the more than 40 years that I did maintenance on the antennas.
The 33 is a 3 element tribander and the 53 is a 5 element.
This can be the reason for future failure or reduced efficiency. Contact the site with comments or questions. The tubing must be well heated and we both use an electric hot air gun.
If you want to replace the aluminium look for companies that provide fencing for farmers. Dort habe ich die Kopien aus der Original-Montageanleitung eingestellt.
Aber vielleicht hat ja noch einer hier die vom FB33!? I had a FB53 14 years ago. Vy 73 de Eckart. My more than 35 years old Fritzel antenna elements look new after a thorough maintenance. Radiator — Reflektor mm. So it fits exactly on the aluminium cover of the trap.
Till then I was quite happy with the beam. StrahlerReflektorAbstandalles mm ich habe keine 7,80 hier in den Unterlagen. In principle, a trap is a capacitance in parallel with a coil. Gehe zu Seite 12. Apart from the permanent damage caused to the hot toroid, the shell partially melted and changed shape.
Servus, ich habe einen ca. If only the tip of the plastic coil form is applied with some silicone grease you ensure that the construction remains “water resistant”. Further in this article describes how with a dipper the dismantled trap is measured.

Remove oxidation, dirt and apply silicone grease as a protection to. When I purchased it, it seemed that most of the hams around here had one. Im Hinblick auf die verwendeten Begrifflichkeiten, wie z. For an antenna which has been in operation for close to 30 years, the wear and tear is negligible; proof of good workmanship.
In seinem Forum wird es Verweise auf die archivierten Threads in frotzel Forum geben und frotzel diesem Forum wird generell das neue Forum fh werden. Be carefull with power over Watt as the traps tend to blow.
Never mind about the floppy balun. Email Subscription You are not subscribed to this review. By first removing the burned part with a cutter, ON4LN successfully restored 33 staircase with two-component epoxy.
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 surface is 45 times increased compared with a wire eyelet plus rivet. Ich betreibe einen FB33, den ich etwa gekauft habe. So I would advise buy a M2 or Fluid motion Steppir.
It’s in use for about 3 years now and the only problem I had was with the optional Fritzel balun that got full of water about a year ago. Erhebung von Zugriffsdaten und Logfiles Wir, bzw. Rain and fv does not affect the SWR.
The Fritzel company is good to deal fritael and have many other fine antenna products such as verticals, wire antennas, baluns, and a really wonderful antenna wire which is multistranded flexible Cu wire with a nice flexible uv resistant PVC coating. By regular “polishing” the surface becomes smoother and oxidation has less chance to penetrate the elements.
Often people ask me the size of the elements. The case of the older type trap has a diameter of 4 cm and the diameter of the newer model is 5 cm. His company produced frjtzel types of antennas and later then they made antennas for more power. Der Begriff reicht weit und umfasst praktisch jeden Umgang mit Daten. The damage appears low on the picture because I restored the plastic with hot air and I glued the cracks a bit.
The traps of this antenna are qua, construction, size and number of turns identical to that of the next vertical antenna GPA Can hear things like never before. With back and forth motion the crystals works as sandpaper so you may manage it usually.
I had it in the air 24 m for only 1 year and lost the beam in a storm. For example the antenna resonates only on two bands, but does not work on the third one. Drilling of the rivet and replaced by screw or bolt with nut is than the only cure.
Deswegen tut sich auch kaum etwas wenn die Antennen gedreht werden.
