Specifications:

Part Name: Antenna Kit

Material: Metal

Color: As shown

Frequency Range: 7MHz (40m band) ~ 50MHz (6m band); Only band can be used at a time; Compatible with the 7MHz, 10MHz, 14MHz, 18MHz, 21MHz, 24MHz, 28MHz, and 50MHz amateur bands, and resonates on non-amateur frequencies in the 7-50MHz range. (7MHz requires an induction coil; other frequencies require adjusting the telescopic antenna.)

Connector: M10

Weight: Approximately 1.8 kg

Power handling: 100 W

Impedance: 50 ohms

Number of balanced cables: 3.5 m x 4

Size: Telescopic length: 5.6 m

Notes: (see below)

To facilitate quick installation and resonant point finding, the telescopic rod is marked with various common frequency scales (based on a 10-meter feeder cable). When using a feeder cable shorter than 10 meters, the oscillator may need to be extended due to environmental and ground grid factors. (When using a 2-meter feeder cable or installing on dry ground or a rooftop, an additional telescopic rod will be required above the scale.)

Instructions: (see below)

Step 1: Remove the 50 cm (12 in) rod, base, and ground stake from the protective sleeve. Install the 50 cm (12 in) rod into the threaded hole in the base and insert the ground stake into the ground.

Step 2: Remove the wire collector, unplug the ground wires by , and insert a banana into the hole in the base.

Step 3: Screw the 7MHz induction coil into the upper end of the 50cm pole, then screw the whip antenna onto the 7MHz induction coil. This coil is only for the 7MHz band. Remove the coil when using other frequencies.

Step 4: Extend the whip antenna section by section. For example, when using the 7MHz band, install the 7MHz induction coil between the whip antenna and the 50cm pole. Pull the whip antenna upwards section by section until it is close to the 7MHz markings. Due to environmental factors, some adjustments may be required, as the markings may not be optimal. When using the 14MHz band, the 7MHz induction coil cannot be installed. Extend the antenna section by section until it stops near the 14MHz position.

- Both the 7MHz and 10MHz bands require the installation of an induction coil.
