In this weekend's ARRL 10m contest, one of the antennas I'm using is a vertical folded dipole fashioned from transmitting quality 300 Ohm window line and matched at the TX end via a 4:1 balun. I'm running only 100 watts for this contest, but it can handle full legal limit with ease. This antenna system provides a minimum VSWR of about 1.4:1 at resonance (28.5 MHz) due to the slight mismatch (75 vs 50 Ohms) and less than 1.7:1 at the 10 meter band band edges. 73, Gus Hansen KB0YH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
