Mantelwellensperre / RFI-Choke 1KW

Product information "Mantelwellensperre / RFI-Choke 1KW"

Mantelwellensperre / RFI-Choke 1KW Version

Diese Mantelwellensperre vermeidet, dass die Abschirmung des Koaxialkabels nicht Teil des Antennensystems wird und ungewollt abstrahlt. Darüberhinaus dient sie der Anpassung des unsymmetrischen Koaxkabels an symmetrische Antennen und kann daher auch als "1:1" Balun verwendet werden.

Durch den Aufbau nach dem W2DU Prinzip, ist die Mantelwellensperre 1KW extrem breitbandig und verlustarm. Eine Vielzahl von hochpermeablen Ferriten werden auf hochtemperaturfestes PTFE Koaxkabel gefädelt, eingeschrumpft und entsprechende Stecker montiert. Somit lässt sie sich leicht in die Koaxzuleitung integrieren.

Die Mantelwellensperre 1KW ist ca 45cm lang, sehr breitbandig und verfügt über ca. 1000 Ohm Sperrdämfung im Frequenzbereich von 160m - 2m. Sie ist wetterfest eingeschrumpft und hat 2 hochwertige PL259 Stecker mit PTFE-Dialektrikum und Goldkontakt an den Enden. Ein PL258 Verbinder auch mt PTFE und Goldkontakt ist im Lieferumfang enthalten.

WICHTIG!

Platzieren Sie die Mantelwellensperre 1KW im Falle einer End Fed-Antenne nicht direkt am Speisepunkt der Antenne!
Zwischen dem Transformer der End Fed und der Mantelwellensperren sollte ein Koaxkabel mit einer Länge von >= λ 0,05 (bei 80m etwa 4,20m) eingefügt werden.

End Fed Multiband Antenna for 10-15-20-40-80m 300Watts
End Fed Multiband Antenna for 10-15-20-40-80m 300Watts PEP Phone You don't have time to build an Endfed Multiband Antenna? No problem. We offer you a ready assembled End Fed Multiband for the bands 10-15-20-40-80 meters up to 300 Watt PEP Phone. The antenna is tuned to band center. You only have to tune the antenna (as usual) minimally to the desired band section. This End Fed Multiband Antenna includes the following parts in addition to the standard components:Mounting plate, ring, thimble, ground connection, deluxe extension coil and a pressure equalization valve. This End Fed Multiband Antenna comes with: Copper/Kevlar antenna litz wire This antenna litz wire is manufactured specifically for antennas. The litz consists of a Kevlar core with approx. 1.1 mm2 tinned and fine stranded copper conductors. 1x 0.4 mm Kevlar and 24x 0.25 mm copper. The jacket is made of black UV-resistant PE. The total diameter is approx. 2.5 mm. The tensile strength is approx. 50 kg. You will receive a strong, flexible and relatively light antenna litz wire. Type: Multiband Length: approx. 23 meters Connection: PL Max. Power: 300Watt PEP Phone Weight: ca  650g Info The measurements for this antenna were made on two 12m spider beam masts, 10 meters above the ground, in an open field, without any buildings.

End Fed multiband antenna DIY kit for 10-15-20-40-80m 300Watt
End Fed multiband antenna DIY kit for 10-15-20-40-80m 300Watt PEP SSBNew extended kit! This kit contains all the necessary components to build an EndFed 1:49 multiband antenna for the bands 10-15-20-40-80 meters up to 300 Watt PEP Phone. We have added a connection for the counterweight and the useful stainless steel ring etc. to the kit. This End Fed kit is supplied with the antenna wire of your choice: Standard antenna wire: This antenna wire consists of 1.0 mm2 fine stranded copper conductor with black PVC insulation. The total diameter is approx. 2 mm. Ideal for experiments or vacation antennas. As the core is only made of copper, this stranded wire will become slightly longer and therefore thinner over time. The tensile strength of this stranded antenna wire is limited. Copper/Kevlar stranded antenna wire This stranded antenna wire is specially manufactured for antennas. The stranded wire consists of a Kevlar core with approx. 1.1 mm2 tinned and fine-stranded copper conductors. 1x 0.4 mm Kevlar and 24x 0.25 mm copper. The sheathing is made of black UV-resistant PE. The total diameter is approx. 2.5 mm. The tensile strength is approx. 50 kg. You receive a strong, flexible and relatively light antenna strand. The kit contains the following components: 1x toroidal core FT-240-431x enameled copper wire GR2 for winding the toroidal core (1mm) approx. 1.50 meters1x polycarbonate housing with transparent cover 100x100x60 mm (IP67)1x mini insulator 65 * 15mm2x simplex terminals up to 2 mm wire (wire rope terminal) 1x thimble approx. 23.5 meter antenna wire 1mm² black 1x capacitor 100pF 2kV DC 1x PL259 panel jack 1x extension coil 110uH ready wound and measured 1x shrink tube black 25.4-12.7mm 1x various screws, washers and nuts made of stainless steel 1x stainless steel ring 3x Fast-On ring contactType: MultibandLength: approx. 23 meters Connection: PL Max.
