Radioddity HF-009 User Manual

Congratulations on purchasing our new multi-band HF antenna. You now have the perfect antenna for
portable and temporary ham radio operation.
The Radioddity HF-009 antenna is supplied in a special " Carrying bag " (#8). The 5 parts of the
•
antenna are located in the lower part. The three " Ground radial wires " (#5) and the "Antenna coax-
cable" (#6) are located in the upper zip compartment
The Radioddity HF-009 antenna is ideal for POTA-operations as it is set up in less than 2 minutes.
•
Properly adjusted it provides an excellent Rx and Tx solution for your HF radio.
The Radioddity HF-009 antenna weights around 1 kg. The "Carrying bag" (#8) can be conveniently
•
carried on your shoulder or in your hands.
The Radioddity HF-009 antenna covers a full frequency range from as low as 60m (5 MHz) up to 6m
•
(50 MHz).
The Radioddity HF-009 antenna works as a 1/4 wavelength antenna. For bands below 17m (18MHZ)
•
a "Tunable loading coil" (#3) is supplied and the "Telescopic whip" (#4) should be fully extended.
Now adjust the inductance of the "Tunable loading coil" (#3) by moving the red cursor upwards (for
higher frequencies) or downwards (for lower frequencies). A tip is to apply tape alongside the scale
of the "Tunable loading coil" (#3) and to mark positions for each band's resonant point.
Frequencies above 17 meters (18MHZ) can not be tuned using the "Tunable loading coil" (#3). Either
•
remove the "Tunable loading coil" (#3) or move the red cursor to the top most point. Now adjust
the length of the "Telescopic whip" (#4) to resonate the antenna at the required operating
frequency. For the highest frequencies the "Telescopic whip" (#4) will not be extended very far
whereas for lower frequencies down to 18MHz more of the "Telescopic whip" (#4) will need to be
pulled out.
The Radioddity HF-009 antenna comes with all you need, including 5m "Antenna coax-cable" (#6)
•
with PL259 plugs on its ends and a "BNC-m to SO239 adapter" (#7) suitable for Xiegu radios.
You can drive the Radioddity HF-009 antenna with a signal of up to 100W CW or 150W PEP SSB
•
allowing its use with most transceivers or suitable HF amplifiers driven with a QRP radio.
Attention: The antenna is a metal conductor. Keep it far away from unsafe positions such as high-voltage power
cables. Please use appropriate lightning protection if this device has to be operated during a
thunderstorm to prevent harm to persons and equipment. We recommend, however, that you
completely take down the antenna and do not use it in such weather conditions. The antenna is not
suitable for permanent outdoor use and must be protected from adverse weather conditions (e.g.
wind and rain).
