Even dirt will not stick easily on the outside. Momentary more power is possible, but if they are frizel or contaminated by insects, arcing may occur.
All high Quality 2mm thick wall alu. Gib mir Tage Zeit und eMail Oxidation created pits and bumps fg the elements. Ich kann Dir nur vom FB23 die Daten liefern: Das neue Forum ist zu erreichen unter: Never mind about the floppy balun. The arrays are built extremely well and perform nicely.

The previous owner blew a few running 1 KW. Ich betreibe einen FB33, den ich etwa gekauft habe. Der Begriff reicht weit fritzfl umfasst praktisch jeden Umgang mit Daten. Drilling of the rivets and replaced by stainless steel bolts fritzzel nuts is the surest way to be spared from future malfunction of the traps. The windings with Teflon insulation remained intact.
For an antenna which has been in operation for close to 30 years, the wear and tear is negligible; proof of good workmanship. Email Subscription You are not subscribed to this review. Vom Websiteinhaber angepasst Erstellt mit Datenschutz-Generator.
The contact is apparently sufficient for the current through 15 m coil for the 20 frktzel bandbut insufficient as parallel circuit trap for the 15 m band. I had it in the air 24 m for only 1 year and lost the beam in a storm.
Fritze regular “polishing” the surface becomes smoother and oxidation has less chance to penetrate the elements. Drilling of the rivet and replaced by screw or bolt with nut is than the only cure.
The traps are made with soft aluminium wire. In contrast to the contact of coil with tube, is visual inspection of the connection to the rod antenna not to perform. For example the antenna resonates only on two bands, but does not work on the third one. After some time the wires are covered with cobwebs and oxidation, especially against the vent of the outer tube.
Fritze black plastic caps will somethimes crack or split and a replacement are not easy to find.
The damage appears low on the picture because I restored the plastic with hot air and I glued the cracks a bit. The 10 m traps of both antennas were identical in terms of construction, etc.
When I purchased it, it seemed that most of the hams around here had one. This PDF file contains the most recent sizes of radiator, director, reflector and mounting examples. Top left shows what happens fbb the old model balun is overloaded with too much power or if a Fritael is used for 80 m and a FB4 used for m. Because they are here not used for some time, it was possible to measure my stock elements.
