Note:
- Other items pictured are not included, for demonstration purposes only. Thank you for your understanding!
In order to facilitate the erection and find the resonance point, the common frequency scales (based on the 10m/32.8ft feeder) are coded on the telescopic rod with a laser. When the feeder is less than 10m/32.8ft, the length of the antenna element may need to be lengthened due to environmental and counterpoise (when using a 2m/6.6ft feeder, dry ground or roof erection, one more section of the telescopic rod needs to be stretched on the basis of the scale).
Use Method:
Step 1: Take the 50cm rod, base and ground stake out of its protective sleeve, install the 50cm rod into the threaded hole of the base, and plug the ground stake into the ground.
Step 2: Take out the wire collector, remove the counterpoise wires one by one, and insert the banana plug into the base hole.
Step 3: screw the 7MHz induction coil into the upper end of the 50cm rod, and then screw telescopic antenna into the 7MHz induction coil. The coil is only required for 7MHz. When using other frequencies, please remove the coil.
Step 4: Pull out the telescopic antenna section by section. For example: when using 7MHz, install the 7MHz induction coil between the telescopic antenna and the 50cm rod. Pull the telescopic antenna upwards section by section until it is pulled to a position near the 7MHz character. Due to the influence of the environment, users need to make some minor adjustments, because the use effect of the lettering is not necessarily the best. When using 14MHz, the 7MHz induction coil can not be installed. Pull out the antenna section by section until it stops near the 14MHz position.
