Coax cable with integrated RFI choke

Product information "Coax cable with integrated RFI choke"

This pre-assembled coaxial cable with integrated RFI choke for End Fed antennas is ready for immediate use. Thanks to its design based on the W2DU principle, the common mode choke is extremely broadband and low-loss. It effectively prevents the shielding of the coaxial cable from becoming part of the antenna system and radiating unintentionally. It therefore provides effective protection against unwanted RF interference. It also serves to adapt the unbalanced coaxial cable to balanced antennas and can therefore also be used as a “1:1” balun.

A variety of highly permeable ferrites are threaded onto lightweight HF-195 FX-ZH low-loss coaxial cable, shrink-wrapped and assembled with connectors as required. The integrated RFI choke (common mode choke) is installed at the end of the cable after 2.10m for the 10-40m bands or after 4.20m for the 10-80m bands. We offer lengths of 10, 15 and 20m. Other lengths can be produced on request.

The lightweight coaxial cable with integrated RFI choke (common mode choke) is also ideal for portable use when traveling, QRP, COTA, POTA, IOTA, SOTA (Summit on the Air) or DX expeditions.

Mini Endfed Antenna Kit for 10-15-20-40-80m
Mini Endfed Antenna Kit for 10-15-20-40-80m, max 100 Watts PEP and 1:49 Transformer The Mini Endfed is a small endfed antenna solution for mobile use, travel, QRP, SOTA (Summit on the Air) or DX expeditions etc. The IP65 protected polar carbonate housing with a size of only 64x58x35 mm, can be easily stored in your pocket or backpack. The weight is about 250-500 grams, depending on the length of the spotlight. The kit has both a connector for the ANTenna and GND for a counter poise capacitance. We have also integrated the M4 ring. This makes it very easy to attach the Mini Endfed with a carabiner and use the thimble as a strain relief. All screws, nuts and the ring are made of stainless steel. If you attach the antenna to the top of a telescopic mast and slide out the mast segments, you are on the air within minutes! To attach the body of the 1:49 Transformer to a mast, you can use the same bracket as used by our active antennas. This End Fed Multiband Antenna comes with the antenna wire of your choice: Standard Antenna wire: This antenna litz wire is made of 1.0 mm2 fine stranded copper conductor with a black PVC insulation. The total diameter is about 2 mm. Ideal for experiments or vacation antennas. Since the core is only copper, this stranded wire will always elongate a bit over time, making it thinner. The tensile strength of this antenna strand is limited. 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. These complete Mini End Fed Multiband kits are designed for 100 Watt PEP Phone and are available in these configurations: 10-20-40 meters approximately 20 meters in length, without extension coil.10-20-40 meters, approx. 12 meters length, with 34uH extension coil10-15-20-40-80 meters, approximately 21 meters in length with 110uH extension coil.

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.

Mosquito End Fed 1:9 Antenna
Mosquito End Fed 1:9 Antenna Mosquito End Fed – small and light After the Mini-End Fed was so well accepted, we looked at how we could make the whole thing even smaller, more compact but robust. The main focus here was on weight. The result is the Moskito End Fed. Mosquito? Yes, because it is so tiny and light. The cylindrical housing with a height of only 70mm and a diameter of 25mm weighs just 50 grams. This makes the Moskito easy to stow in your pocket or backpack. The maximum output is 50 watts SSB PEP. It is available in 1:49 and 1:9. This makes the Moskito End Fed antenna ideal for portable use when traveling, QRP, COTA, POTA, IOTA, SOTA (Summit on the Air) or DX expeditions etc. The Moskito End Fed is suitable for the new generation of small multiband/multimode QRP transceivers such as the Icom IC-705, Xiegu G90 or X6100, LAB 599 TX500 or the Yaesu FT-817/818. Super light antenna wire To match the lightweight Moskito End Fed, we offer the new, super lightweight and high-strength antenna wire SL as an option. This antenna wire is only 1.6mm thick, weighs 4g per meter and consists of 6×0.25mm tinned copper wires. The stranded wire has a core made of tear-resistant Vectran fibers® and a weatherproof PE insulation. This achieves a maximum breaking load of up to 60kg! If you attach the antenna to the top of a telescopic mast and slide out the mast segments, you can be on air within a few minutes! To attach the housing of the 1:9 transformer to a mast, the mini insulator and a carabiner are all you need. Counter-poise If a counter-poise is required, you can connect a short piece of wire/strand with a length of 0.05 λ to the side connection of the mosquito antenna. The counter-poise should hang down freely.
