At this moment they have decided that the SteppIR is an excessive antenna and I may be forced to remove it and get me a smaller antenna name one that does 6 to 40 mtr with a smaller diameter or surface! For an antenna which has been in operation for close to 30 years, the wear and tear is negligible proof of good workmanship. This lightweight square tower went down with the antennas fbb33 a light storm during the evening of December 28th in Contact the site with comments or questions.Īssembling is much easier, because the holes are drilled and everything is fixed with screws. I decided to put one steel pipe with the Yaesu rotor at the far side of the house, nearby the shack with one on dritzel to reach a height of 30 ft.
Three antennes were no problem for the stronger built tower but for my neighbours it was a ugly sight. ON4LN wrote to me: FB33 Direktor ist nicht beschrieben, sorry 73 Peter.
If you want friyzel buy something 2nd hand, look at the size of the traps, the diameter of the tubes and the version of the balun. Very soon the 13 element beam came up for MHz and also one for 70 cm, a 21 element, also from Tonna and several other antennas for different bands. The contact is apparently sufficient for the current through 15 m coil for the 20 m band frtizel, but insufficient as parallel circuit trap for the 15 m band.Įmail Subscription You are not subscribed to this review. Amateurfunk Forum ĭie Abmessungen der verschiedenen Versionen sind hier zu finden: By first removing the burned part with a cutter, ON4LN successfully restored a staircase with two-component epoxy. Drilling of the rivets and replaced by stainless steel bolts and nuts is the surest way to be spared from future malfunction of the traps.įritzel model 83 trap, Bottom: With my call they offend other radio amateurs and people and accuse them of several things. Apart from the permanent damage caused to the hot toroid, the shell partially melted and changed shape. This can be the reason for future failure or reduced efficiency. I used it on quads overe there and it was wonderful.

Drilling of the rivet and replaced by screw or bolt with nut is than the only cure.Ī couple of days later I bought a 24 feet 8 meter antenna tower with a manual hand winch to raise and lower it. The thickest aluminium rod in the new model has a diameter of 28 mm.

Remove oxidation, dirt and apply silicone grease as a protection to. Aber vielleicht hat ja noch einer hier die vom FB33!? Where to put them: His company produced many types of antennas and later then they made antennas for more power. On top I had the old 4 element 50 MHz antenna. Even a treatment with silicone spray works preservative on the coils and antenna rods. 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.
