Steve also might chime in here with the perfect answer once he knows the . I plan to use a SGC-2autotuner and ladder line to feed a multiband loop antenna.

Since the impedance at the end of the ladder line can vary from fairly high on some bands to fairly low on others, and since it is also highly reactive on some bands, I prefer not to use a balun on the output side of the SGC. Großbritannien ist dies der Fall. Sorry for that, but I have no other possibilities. Explanation: What is a current balun ? Broadband current balun 8-MHz: 1. Measurements of current baluns. The windings are spread out evenly around the cores.

I evaluated this core with 100W for one minute into a ohm load and about 3ohm load at 3. With a ohm load I could not detect any increase in temperature.

If you want to make a 500W version use. This was a little bit of a compromise as . Nieuw: De gekende FT1- 43. Transportverzekering besckikbaar. Ringkern gewikkeld voor het maken van baluns en eindegevoeden antennes.

I needed to build some small baluns for vertical dipoles and arrays, to be used on the T2GM dxpedition. Balun UNUN Antenna INDUCTOR Ring.

First I tried a W1JR type on a FT1- core. MHz with a continuous power rating of 1W. It uses UHF connectors, RG3coaxial cable and a FT1- ferrite Toroid. The line Isolator to be constructed is very similar to the .
