Hi A question about wire ... I have constructed a 3/8 for 160 meter. I use the tower to support the antenna. It runs 22 meter vertically and then (horisontal for 24,5 meters (i.e. total 46.5 meter). distance from tower is 1 meter. A the base of the antenna it is feed with a serial capacitor of 430 pF (a 330 in parallel with a 100pF : both door noob). Ground is a combination of 4 ground rods and wire (space is limited). Best swr @ 1860 Khz is 1:1.4. 1:2 bandwidth is app 80KHz. A noise bridse have shown impedans around 70+j1. Currently the wire is 1.5mm stainless steel wire. How much would the antenna be improved if i substitute the SS wire with with 1.5mm braided copper wire? I guess the seial capacitor would change as well ? any idea how much ? Antennewire i use ( steel 40050 and copper: 40051): http://www.wimo.de/cgi-bin/verteiler.pl?url=wireantennas_e.html -- OZ1AXG Flam _______________________________________________ Antennaware mailing list Antennaware@contesting.com http://lists.contesting.com/mailman/listinfo/antennaware |
