30W QRP Shortwave Antenna 5MHz-55MHz HF Antenna Full-Band Antenna Tuned SW Aerial FM Aviation UV for UHF VHF

Project type: qrp shortwave antenna

Material: aluminum alloy, steel

Power: 30w

Adjustable frequency: 1.8mhz-30mhz vhf uhf

Frequency range: 3.5~30mhz, 50~54mhz, 76~108mhz, 117~136mhz, 136~174mhz, 400~470mhz

Power: Less than equal 30W

SWR: Less than equal 1.5

1. Portable and easy to use: The portable small circular antenna can easily and quickly set up the antenna for your shortwave transceiver antenna.

2. Practical function: Allow you to enjoy multi band reception and communication indoors, through windows, on balconies, and outdoors.

3. Adjustable with knob: Short wave high and low frequency bands can be adjusted for transmission and reception.

4. Extended usage method: Remove the telescopic antenna. Connect a 20 meter long wire and install a long cable rack on a high place or roof, which can replace a telescopic antenna.

5. Main applications: Used for sending and receiving, aluminum alloy and steel materials, corrosion-resistant.

6. The band is adjusted by the upper knob on the tuner panel, and the SWR is adjusted by the lower knob.

7. The tuner connector is a male M connector. Three adapters are included: L-type female M connector - BNC male connector, L-type female M connector - male M connector, and straight female M connector - BNC male connector.

8. 1.8-30 MHz, antenna extends to 2 meters in length, with a 14 MHz inductance coil, meaning 14 MHz is the natural resonance frequency, and the other frequencies are compensated by a small antenna tuner. The rated power tolerance is 30W, and the power tolerance for the 14 MHz band is doubled. For the UV band, remove the two extension rods and the inductance coil, and directly screw the telescopic antenna onto the tuner. The antenna installation position has hand-tightening screws and copper lugs. You need to solder a 20-meter-long wire to the copper lug, which will serve as a long wire antenna.

9. Antenna tuning steps: Connect a 5-meter-long wire to the M connector housing of the antenna as a ground wire. Turn the upper knob to the 14 mark and the lower knob to the 3 mark. Connect the antenna analyzer. Pull out the telescopic antenna fully and retract it by one section. Observe the curve on the antenna analyzer and fine-tune the telescopic antenna to find the 14.270 MHz resonance point. Mark the length position of the telescopic antenna with a marker pen. In future use (for all bands), use the marked position as the reference for the best point!
