The antenna impedance (R+jX) merely depends on the ground plane, but will be rather capacitive (negative X). To feed the antenna with 50 ohm coaxial cable, a match is required to transform the antenna impedance to 50 ohms (50+j0). We measured the impedance of our 15m antenna: 53-j328 ohm. So R=53, and X=-328.
  • Using an antenna tuner is the only way outside of using a 100% resonant antenna to keep that signal going It may not be physically tuning the antenna, but it is tuning the antenna to the system load...
  • ICOM IC-756PRO transceivers are designed with hardware that produces 100 watts. Many special features that rely on the 100-watt hardware are included with this advanced transceiver such as a voice keyer and a noise blanker component. A built-in antenna tuner helps insure that radio frequencies are always strong when the advanced features are used.
  • If your antenna has a stable impedance of 450 ohm over 3-50 MHz, than you don't need a tuner, otherwise you still need a tuner, but this balun helps a lot to tune wires to 50 ohm. In my case i can easily tune a 5 m length wire to 80 m band with LDG 100 tuner, without this balun i cannot tune this short wire.

    based impedance tuners are small enough to be mounted inside an on-wafer probe. An impedance tuner can either be of the transmission or reflec-tion-type (Fig. 1) design, and typical impedance tuners are based either on double-stub [6, 7] or tri-ple-stub topologies [8, 9]. The stub topologies are not ideal for power amplifier applications since

Actually, a fixed matching transformer can dramatically reduce the wild swings in antenna efficiency that a coax fed wire antenna exhibits. Let us calculate: The following graphs are based on a 15 meter vertical antenna, fed at ground level, using a conical approximation.

Jul 31, 2018 · Because a tuner is strongly recommended, the antenna can be fed with 75Ω coax, a very good match to the antenna’s impedance.
