Copper/Kevlar Antenna Wire

Mini Endfed antenna kit, max 100 watts for 10-15-20-40 meters approx. 20 meters long, without extension coil The Mini Endfed is a small End Fed antenna solution for portable use, when travelling, POTA, QRP, SOTA (Summit on the Air) or DX expeditions etc. The IP65 protected housing made of polycarbonate with a size of only 64x58x35 mm can be easily stowed in a pocket or backpack, but is also robust enough for stationary mounting. The weight is around 400-500 grams, depending on the length of the antenna. 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 1:49 transformer to a mast, the same bracket can be used as for our active antennas. This Mini Endfed kit is supplied with an 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. These complete Mini End Fed Multiband kits are designed for 100 Watt PEP Phone and are available in these versions: 10-15-20-40 meters approx. 20 meters long, without extension coil 10-20-40 meters, approx. 12 meters long, with 34uH extension coil 10-15-20-40-80 meters, approx. 21 meters long with 110uH extension coilThe kit contains the following components: approx. 20.45 meters of antenna wire 1x stainless steel cable clamp 1x end insulator 1x cable lug 5mm 1:49 Mini Impedance transformer: IP65 housing 64x58x35mm polycarbonate Toroidal core FT140-43 Enameled copper wire GR2 quality 1.00 mm 100 pF capacitor 2kV 1x BNC flange socket 2x M2.5 screws 8/10mm 2x M2.5 nut 2x M2,5 washer 1x cable lug 3mm 3x M5 cable lug 2x stainless steel M5 screw 20mm 2x stainless steel M5 wing nut 2x stainless steel M5 collar nut 2x stainless steel M5 toothed washer 2x stainless steel M5 screw 20mm 2x stainless steel M5 wing nut 2x stainless steel M5 collar nut 2x stainless steel M5 toothed washer 1x ring M4 1x toothed washer M4 1x nut M4 1x cable thimble

1:9 UNUN transformer for the frequency range: 1-30MHz and a maximum transmission power of either 600W or 1500W PEP. The IP67 housing is of course made of UV-resistant polycarbonate. Including connection for a counterweight and, for market launch, with mast mounting shown. All screws and nuts are made of stainless steel. The PL or N sockets used are high quality and PTFE dialectic. A tuner is required for non-resonant antennas. The following wire lengths have proven to be useful:6.5m - 6.9m - 13.5m - 13.9m - 16.2m - 20.8m - 22m - 26m - 27.7m - 34.7m - 41.6m - 48.5m - 55.5m You can find suitable antenna strands here: Copper Kevlar stranded wire Translated with DeepL.com (free version)

Complete 1:4 BalUn DIY kit for off-center-fed (windom) antennas, among other things. 1:4 BalUn 600 Watt self-build kit 1.8 – 30 MHz, with solid strain relief. This 1:4 BalUn is constructed from two FT240-43 ferrite toroidal cores. On the first toroidal core a 1:1 current BalUn is built up. It takes care of the transition from unbalanced (coax) to balanced antenna. This BalUn has a fantastic common mode current attenuation of over 30 dB. The second toroid is responsible for impedance adjustment from 50 ohms to 200 ohms. Many BalUn manufacturers only look at the impedance matching but forget to look at the common mode current attenuation. This BalUn scores very well on both levels. Now with a handy mounting plate to attach both ring cores, so gluing is no longer necessary. The 1:4 BalUn 600 Watt can be used for off-center-fed antennas, among other things. The off-center-fed antenna (windom) is a popular multiband antenna. These antennas have many advantages. The antenna can be used on many bands, the antenna is often easy to place due to the 1/3, 2/3 ratio in the antenna legs. By using a good BalUn, Common mode current are prevented, which also reduces interference from your direct environment. This antenna needs no ground or counter capacitance. The main reason for using a BalUn is to make sure that the coax cable is not part of the antenna system and that it will radiate undesirable. This has all sorts of nasty effects, think of: interference, EMI, RFI disrupted radiation pattern of the antenna, restless noise level. This last point is because not only does the coax cable’s shield radiate when you transmit, but the shield also works as a receiving antenna. 1:4 BalUn 600 watt components This kit includes: IP65 enclosure 100x100x55 mm 2x Ferrite Ring Core Amidon FT240-43 Winding wire 18 AWG – 8x 85cm PTFE 19 x 0.25 mm copper “Silver plated” PL 259 Chassis Toroid mounting plate 4x M3 spacer 4x Stainless steel M3 6 mm screws 4x stainless steel M3 washer M3 Cable lug 2x M5 Cable lug 2x stainless Steel (A4) M6 eye (Strain relief) 2x Stainless Steel M6 Nut 2x Stainless steel M6 washer 2x stainless steel M6 Spring washer 2x Stainless Steel M5 Bolt 25mm 2x stainless steel M5 wing nut 4x Stainless Steel M5 Nut 4x Stainless steel M5 washer 2x stainless steel M5 Spring washer 4x stainless steel M5 toothed washer 4x stainless steel M3 Bolt 12mm 4x Stainless Steel M3 Nut 4x Stainless steel M3 washer 4x stainless steel M3 toothed washer
