OK, this is application of above antenna. Notice the radials drooping over
front of wings and one of the rear radials on right.
Band fixed by red center coil, with coils for 40m, 20m, 17m. Tuned by bottom
coil. This is for use with qrp 40m rig. This one made several qsos back to
Shreveport from Dayton Hamvention and packs into a 12 inch bag.
Z-match - tunes a wide range of antennas
This version built with toroid.
This QRP small tuner will tune end-fed half-wave antennas for 40m, 30m, and 20m.
In addition there is a switch to bypass the L-match (toroid and trimmer cap)
and output to another BNC. An SWR bridge with LED may be used in all four
of the above modes.
Random wire tuner. Inductor is coil around ferrite rod with sliding contact.
Tuning LED is to right of SO-239.
This is a tuner designed to tune half-wave wires, of which the counterpoise
can be only .05 wavelength long. It is designed to handle 100w where the
Altoids can tuner will only handle about 30w. A separate half-wave wire for
each band must be used, but the 40m wire can also be used on 20m. Since
end-fed half-wave antennas have approximately the same reactance, only the
capacitor is needed to tune.
