Hi All,
It is good to have new ideas granted, but old timers in this
hobby don't like newcomers to have to "rediscover the wheel". Switching
lengths of an antenna by relays is doing it "the hard way". A
non-resonant antenna fed with ladder line or open wire feeders is a far
more practical solution for a multiband antenna.
