Hello everyone!
There's now brand-new steel roof over me and time to put up a vertical. Dont want to spent too much time over that slippery and rather high roof messing with traps, so: planning to put up a fishing pole (7 m long) and coil wire around it. Would like to use rig's autotuner and short run of rg6 cable. Dont mind swr 5 or so. Played with EZNEC and found that 12 m long radiator would present reasonable impedances at 40, 30, 20, 17, 15. But, when my mast is 7m long, should I coil 12 m or more wire around it?? Should I use capasitators at the base of the antenna to to tune out reactances? Or can tuner do that on the other side of coax? Anyone done something similar? Any comments? Andrus |
