Bob with no tuning? you get acceptable match to your rig without a tuner, would you explain more? thanks Buck I just re-read your statement. Are you saying the whip without a loading coil used thru a tuner? My first thoughts were you meant without a tuner. I expect that 40 and below will be a bit poor. I hope to find a compromise of sorts where I can add a loading coil, but only change it when I want to operate 40-80 meters, sort of a switch between the higher and lower bands as opposed to setting it for each band. The alternative may be to have two antennas, one for the lower bands, set as needed per band, and one for the upper bands that only needs tuning with the tuner. If I am lucky, I may be able to have one with a loading coil that tunes all the lower bands relatively efficiently and the whip for the upper bands. I can deal with two antennas, I have a switch but my problem right now is I have separate 40, 20, 11, 10, and 6 meter antennas. If I want to change bands, I have to replace each antenna. Likewise, if I want to add a band, I have to buy more antennas. I just want to simplify my operation for when I am mobile. I have a 135 foot dipole with 300 ohm feed that I can toss up in the trees for portable operation when I want to be efficient or for emergency operations, but for moving, I don't want to pull off the highway and get out of my car to change antennas every time I want to change bands. Thanks for the input. Buck -- 73 for now Buck N4PGW |
