Antenna litz wire 1.0 mm²

Copper/Kevlar Antenna Wire This antenna litz wire made of copper/Kevlar, is specially manufactured in the Netherlands for use as long wire, endfed, dipole or other antennas. The wire consists of a Kevlar core with approx. 1.1 mm2 tinned copper braid. The combination of Kevlar and copper gives an optimal mix of RF wire and tensile strength of about 50kg. In contrast to the pure copper braid, the length remains stable here, because the braid does not elongate over time. Thus, frequency and SWR remain stable over a long time. The insulation is made of high quality and UV-resistant PE. This antenna wire is therefore durable, strong, still flexible and has with only 14g per meter, a low weight. Ideal for travel (SOTA, IOTA; etc) but also perfect for a permanently installed antenna. Specifications: 1x 0,4 mm Kevlar core 24x 0.25 mm tinned copper. Copper section: 1.2 mm2 Weight: 14 grams per meter UV resistant black PE insulation Total diameter +/-2,5 mm Tensile force approx. 50kg

Wire reel for antenna wire With this reel with 15cm diameter, the antenna wire of the Endfed or Mini Endfed can be wound up safely without bending the wire. Ideal for mobile use when traveling, SOTA (Summit on the Air) or DX expeditions etc. Simply wind the antenna cable onto the spool and stow it in your backpack or bag. The bright yellow color makes it easy to find the reel in your bag. 15cm diameter 24mm wide For about 22m antenna wire with 1mm2

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
