Description
Small whip
3.5-30 MHz, with an antenna that extends 2 meters in length and comes with a 14 MHz inductive coil, which means 14 MHz is a natural resonance. The remaining frequencies are compensated with small tuning, with a rated power tolerance of 30W and a power tolerance of doubling in the 14 MHz range.
The upper knob adjusts the frequency band, and the lower knob adjusts the standing wave
The installation position of the antenna includes hand twisted screws and a copper nose. The copper nose welds a 20 meter long wire on its own, which is a long wire antenna (end feed antenna)
There is no talent meter, no ground cable, and the pull rod antenna is uniformly pulled out and retracted by one section.
Steps for debugging the perfect state of the antenna:
Connect a 5-meter long wire to the outer shell of the antenna head to create a grounding grid. Turn the top knob to scale 14 and the bottom knob to scale 2. Connect the celestial instrument and pull out all the rod antennas before retracting one section. Observe the curve of the celestial instrument and fine tune the rod antenna to find the 14.270 resonance point. Use a marker to mark the length and position of the rod antenna. In the future, use the marked position as a reference for the best point
